Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
@ apubar - Thank you Andrew! It was thanks to your post on the German forum that made me realise I had to file out the hinges. I remembered reading about it. Sure helped big time! Sure glad the cabin is finished. Always worried of scratching the paint.
@egronvold - Must say am rather happy with the white and black myself. Looks better than I thought it would. @Brel - look great indeed but is rather front heavy at the moment. So could do with some weight at the back. Once the roll on/off stuff is on there should still look good without a container. @ crisis time - The amount of screws is what makes it fun! +++++++++++++++++++++++ Haven't done anything to the truck yet. From reading other threads on ScaleART and looking at pictures, I know there is no decent way to prevent the hydraulic lines from swaying when going from the 2 main cylinders to the oil pump. ScaleART fixes them to the cylinder with some shrink tubing or smal zip ties, not really a nice solution all things considered. So I figured to be "creative" and see if I could make some things to hold the line to the cylinder. After more than a couple of failed attempts I finally figured out how to make these simple looking things. Got the width down that I could work with the tools available to me http://i1282.photobucket.com/albums/...psboegpcrt.jpg Messing cut into almost same width strips with scissors http://i1282.photobucket.com/albums/...psvwylki9i.jpg Bend - the driver has the same diameter as the line. http://i1282.photobucket.com/albums/...pswytk4wii.jpg Filed http://i1282.photobucket.com/albums/...pseeblerjc.jpg Make roundish by bending with pliers in small increments (repeat until about right) http://i1282.photobucket.com/albums/...psvg2p2zqk.jpg One done http://i1282.photobucket.com/albums/...pswjip8ybs.jpg 4 done http://i1282.photobucket.com/albums/...pssstbp7i4.jpg and painted. http://i1282.photobucket.com/albums/...psddhfgcmo.jpg Not installing them yet. Will first so a test fitting of the hydraulic cylinders and see if I can use them yes or no. All I can say it that making these 4 simple things has made my respect for those who whip out whole models from scratch, go a lot of notches higher! Hat off. |
Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
Hi Stephan,
that´s a great idea and a well done work. I think, I'll try to copy them. ;) |
Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
Hi Christian, Thanks and I'm glad I finally came up with something you might be able to use. Better wait and see if it works though. If I can use them I will just glue them holders to the cylinder with UHU Endfest.
|
Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
Hi Stephan,
ok, I'll stay tuned ... If you fix them with glue, I think there should be a little space between the cylinders, the lines and the holders, so you'll be able to change the lines if they once become leaky. |
Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
Looks like a great solution to loose hydraulic hoses. Hope that they will work for you. You might want to try some rubber cement to attach them to the cylinder- not sure what cement you mentioned is.
|
Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
Good point Christian, thought about that too! Will only glue the holder to the cylinder first. There should be just enough room to push the hose through without too much effort once the glue has set. That is why I first want to try with a temporary fix (zip tie or tape)on the holders, to make sure the hose does not move too much or rubs. Last thing I want is a leaky hose spouting hydraulic oil! :)
Will see, maybe I have some time tomorrow. Will have to take a good look on how to run the hydraulic lines too. |

You are right though, before I glue it like that, I will first try with something less strong. Thanks for the suggestion! Stephan |
Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
Started on the hydraulics
Prepped the 2 main cylinders. Basically cleaned them of the hydraulic oil that had seeped out. http://i1282.photobucket.com/albums/...psptpsinoe.jpg Added the nipples http://i1282.photobucket.com/albums/...pstgbxswcj.jpg Added some hydraulic tubing so you can see what happens if not constrained in some way. http://i1282.photobucket.com/albums/...pstxnsayn0.jpg http://i1282.photobucket.com/albums/...psefyhcbkr.jpg No problem when completely extended. http://i1282.photobucket.com/albums/...pso4bpotpc.jpg Anyway had to bolt the roll on / of part to the chassis. When I tried to take it off I ran into a problem ... one of the bolts holding it in the back sheared off :mad:. A true WTF moment. Didn't figure I had tightened it that hard. When I took the bolts off on the other side, another one lost it's head :eek:. both of them were the ones at the back of the frame. :confused: This is the part I'm talking about. http://i1282.photobucket.com/albums/...psknnrsodv.jpg Here one of the pieces with the sheared of head. (the other bolt is temporary inserted. Is on the wrong side of the part) http://i1282.photobucket.com/albums/...psgq6b5r2j.jpg Well, spend the rest of the day drilling out the rest of the screw. Stainless steel too. Took forever and broke 3 drill bits. Got both of them out, and luckily the parts are still useable. :) No clue what happened. They were not cross threaded, but were jammed solid. Noticed when I removed the part that is was slightly bend where the bolts were. Should have tightened those 4 bolts evenly. Another lesson learned. Reinstalled the roll on/off assembly on the chassis and everything goes together smoothly. So basically no harm done apart from a couple of scratches made by the drill. But you can't see those anyway. Hopefully next session will be less stressful :) |
Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
Had the reason for my little mishap explained by a person way more proficient in mechanical matters. When I screwed in the bolts, the last couple of turns were not smooth. Most probably this was caused by the black stuff or contamination on the threads. I had previously installed the Roll on / off stuff but never completely tightened the bolts. I should have stopped at once tightening the bolts and taken them back out. Then chase the threads with a tap or else put some copper grease on the bolts. Oh well water under the bridge.
Before I continue here a picture of page in the manual. Makes it easier to follow this posting. http://i1282.photobucket.com/albums/...psbtdrrof4.jpg Spend yesterday evening messing with the placement of my holders and got it all kind of figured out. Glued them on last night and let them cure overnight. This is where I glued them. top one about 1 inch (2.5cm) from the top and the bottom one about 4.5 inch (11.5 cm) from the top. http://i1282.photobucket.com/albums/...ps38w9cjgw.jpg The top one should have been further out. Had to unscrew the nipple to be able to attach the hydraulic hose. Which meant I had to replace the 2 seals also. (Plenty of spare ones supplied) http://i1282.photobucket.com/albums/...pspzmpt9tk.jpg Both cylinders with hoses attached. I make a bit of an error ... the one on the op the hose should point inside. Had to redo that one later in the game. The hose comes rolled up and it does pay to work with the way it is curled. Following the manual, the small ones are 5 cm and the long ones about 17.5 cm. http://i1282.photobucket.com/albums/...psobdqbkge.jpg Now time to fasten the cylinders to the frame and the rest of the mechanism. I had forgotten about those cir-clips. http://i1282.photobucket.com/albums/...pscifnh3mx.jpg Found a way to get them on without too much trouble. Got tweezers that fitted in the opening, and then just stuck in a flat screwdriver and slowly turned the blade opening the clip - did have a couple fly off though, but there are a spares. http://i1282.photobucket.com/albums/...psoi7do77r.jpg Cylinders installed, and connected the short hoses. Immediately I got a knick :mad: Bugger ... replaced it and same story. Ended up with a piece of only 4cm before it behaved itself. It is a pain getting the hoses and the holder on the nipple, but it is even harder getting the bleeding thing off again. Do hope I never have a hose failure. http://i1282.photobucket.com/albums/...pskw3ak3qn.jpg Here a view from the other side after finally (4 tries!) getting the bit of hose to stay in shape. http://i1282.photobucket.com/albums/...pstkucggqa.jpg The longer hoses have to cross over to fit. Here is where the natural curve of the hose comes into play. By having one of the hoses bending the "wrong" way the whole thing got skewed. http://i1282.photobucket.com/albums/...pskwlnbtdl.jpg Connector towards the valves of the short hoses and the longer one after replacement now giving a better curve and not trying to twist away when the cylinders go up. http://i1282.photobucket.com/albums/...psbsclc1vp.jpg and the long ones joined to the line for the valves. http://i1282.photobucket.com/albums/...ps71txjy7m.jpg The rear ones just cross over and run through the holes in the cross members of the frame towards the valves http://i1282.photobucket.com/albums/...psoo4vkotq.jpg Gets a bit busy at the transfer box. The hoses are far enough from the shaft. Only look close in the picture. Might run the 2 hoses coming from the main cylinder over the ones coming from the back though. (noticed I already have surface rust ... sub tropical climate and sea air takes it's toll!) http://i1282.photobucket.com/albums/...pstlgovpz4.jpg All end up here labelled and waiting to be hooked up to the valve body. Sill have to do the lines coming from the tank. http://i1282.photobucket.com/albums/...psjyyanbiu.jpg http://i1282.photobucket.com/albums/...pszknwxyzt.jpg ScaleART delivers the truck with 2.5 meter of hydraulic hose. I had ordered an extra meter just for safety sake. That meter turned out to be 1.25 meter. After finishing this part I measured the left over hose and have about 1.30 meter left. I made some extra pieces so there is enough hose with the kit. Now nursing my sore fingertips. Getting those metal locks on the hoses sure takes its toll. :) Next would be the oil tank and it's lines. According to the drawing they seem to indicate to run the pressure line underneath? Seems a tad weird because that way prone to getting stuck to things when in "rough" terrain. Stephan |
Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
Short update. Am not really happy with the way the 2 short hydraulic hoses run. Just doesn't look right at all.
http://i1282.photobucket.com/albums/...ps3bphkai1.jpg So had another look at it. Took that bit out. For some reason I have about 5 extra nipples so nothing was stopping me to do some little experimenting. I only tightened the nipples about 2 turns, so they could move freely and came to this result: http://i1282.photobucket.com/albums/...psfnx0q4xn.jpg This looked much better and still sticks to the 5 cm ScaleART recommends as length for these pieces. I did try longer pieces of hose thinking to run them through the holes in the holder, but then the coupling connecting them pushes up the other hoses that then interfere with the hook sliding back and forth. http://i1282.photobucket.com/albums/...psjtisnntj.jpg Final installation. Looks much better. Will have to clean up all those bit of loose paint I scraped while messing around and do some retouching. A small bit of double sided tape to hold the coupling in place might prevent further paint damage. http://i1282.photobucket.com/albums/...psziqzhui6.jpg While I was at it took a picture of the back to show how the hoses run there. http://i1282.photobucket.com/albums/...psbanqwk6b.jpg That's it for today. My head is not really with it so I better leave it for now before I make another stupid mistake. Stephan |
Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
Good thing I took some time out. Realized that with the hook mechanism in place and hooked up to the valves, I will no longer be able to move it up or down until pump and electrics sorted out.
Then I would no longer be able to sort out the rear lights! So that is what I did today. Got the rear lights of http://i1282.photobucket.com/albums/...pszk0ymg00.jpg Removed the shrink tube http://i1282.photobucket.com/albums/...psnkuittfh.jpg Covered the back with Liquid Tape and screwed it back on to the support with M2x5 self tapping screws I sourced on the bay. Followed my own advice and first put on the lights and then pulled the wire through the frame. The new shrink tubing is 3mm one. Could barely get the wires through so used some silicone grease on them. The tubing has not been shrunk so it's way more supple too. http://i1282.photobucket.com/albums/...psthfesdhg.jpg Bus connector for the 2 rear lights. http://i1282.photobucket.com/albums/...psnputhe8j.jpg Cable is too short to go al the way to the front. So extended it. Made sure the connections were spaced to avoid a thick area where the 2 unions are. Put some of the Liquid Tape on them before I pulled it through the shrink tube. http://i1282.photobucket.com/albums/...psoadk7te0.jpg Lights plugged in. (only shrank the tube at beginning and end) http://i1282.photobucket.com/albums/...ps68kv8ebq.jpg Bus connector installed inside the cross beam for now. Have to sort out a cover for it later. (Looks like all my wires and hoses are crossing one another) http://i1282.photobucket.com/albums/...psnqjjjevk.jpg Looked at installing the servo for the trailer coupling, but that will be a real pain in the neck without taking the hook stuff off. I'm just going to forget about that for now. Stephan |
Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
Started off with the servos for the valves.
http://i1282.photobucket.com/albums/...psu5emnblv.jpg They get controlled with these two knobs. The further left of right you turn, the wider the valve opens. I am sure they also control the pump through one of the mixer functions. http://i1282.photobucket.com/albums/...psicus5nt4.jpg The valve body. The indent indicates the valve is in the middle potion (closed) http://i1282.photobucket.com/albums/...psozwjnmiy.jpg Side view http://i1282.photobucket.com/albums/...pseumvjdwi.jpg top view http://i1282.photobucket.com/albums/...pswakv9gjn.jpg Front view http://i1282.photobucket.com/albums/...psexwmlfzu.jpg What hose hooks up where http://i1282.photobucket.com/albums/...ps3scndebf.jpg Servo horns cut and corners in plastic cut as per instructions. Pressed in place. http://i1282.photobucket.com/albums/...psj5zweycq.jpg Servos attached. http://i1282.photobucket.com/albums/...psh8ldhtaz.jpg Got some unwanted assistance from one of our cats http://i1282.photobucket.com/albums/...psaumtqs0o.jpg Test fitting tank so I can finish the hydraulics ... http://i1282.photobucket.com/albums/...psb59nomby.jpg And bummer ... I had to move that support didn't I ... the screw holding the earth wire of the motor interferes with the tank support forcing it too much towards the back so I will never be able to get the fender in place http://i1282.photobucket.com/albums/...pspeniw1bq.jpg Tried different solutions, didn't want to mess with the tank support so ended up filing the head of an M3 bolt down to almost nothing - lucky it is only to hold the earth wire - until it the tank fit in place. If I had left the support in place or moved it over one opening more towards the front this would not have been a issue. http://i1282.photobucket.com/albums/...psjcrkk2gy.jpg Hopefully next update I will get around to fixing the tank in place and finishing the hydraulic connections - time permitting.

Great update Stephen. I love this project and I am following it every day.
Great work !! Alan |
Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
Hi Alan, thank you for letting me know! Makes me happy to know you enjoy the updates! Too bad I haven't got the time for one today.
Have to fix the gate camera. Someone cut through the low voltage wiring. :mad: A real bugger of a job repairing that thin cable. Cheers! Stephan |
Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
Holy cow what a LOT of small parts! This is going to be really cool when you get it running!:)

Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
Hi Jim, indeed lots of parts that need assembling. Wish I had the room to place it and the time to learn how to use the equipment to make my own parts like you did. :)

Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
Before I can finish the hydraulics. I need to sort out the oil tank/pump part.
First the straps that hold it to the frame. After removing the bit of shrink tubing that protects the threads, you can see that some of the solder has contaminated them http://i1282.photobucket.com/albums/...psxsfs36xh.jpg Lucky I had an M2 thread cutter. So a couple of minutes later http://i1282.photobucket.com/albums/...pski9qd8fb.jpg As seen on other people's threads, the tank straps are having black rubber underneath. I could use some rubber from an old bike tire, but scaled up from 1/14.5 to 1.1 that bit of rubber would be way to thick. Ended up glueing two pieces of PVC film to one another and cutting some strips and gluing them to the straps with super glue. http://i1282.photobucket.com/albums/...psaiyyeyjk.jpg Installed the tank. The PVC - stainless and Super Glue didn't work. PVC film buckled. Something to deal with later. http://i1282.photobucket.com/albums/...pss3uejbh6.jpg After trying different paths for the hose to go from pump to valve body ended up with this. Looks close to both props hafts, but plenty of room really. Very hard to get a picture of it. And those 4mm clamps that go on the nipple are absolutely impossible to get on. Used a 4.5 mm wrench as aid. (As seen in one of Newcomer_2's threads) http://i1282.photobucket.com/albums/...psuuccuc5s.jpg After sorting how to run both 4mm hoses. Have to connect the 2 hoses from the small kicker cylinder. http://i1282.photobucket.com/albums/...psvf5gss7x.jpg Then attach the 2 4mm hoses, and the rest of the connections. A bit of a job all this. Not really much room the work in. Found it was easier to get the nipples on the hoses and then attach to the valve block. The 4 nipples on top are not tightened yet to allow me to move the hook mechanism up and down. In the picture you can see one 3mm hose underneath the 4mm one at the chassis. I'll get back to that one ... :rolleyes: http://i1282.photobucket.com/albums/...pskixpqvy9.jpg After this tightened up de straps of the oil pump after cutting 2 new strips from the PVC film. This time I just shoved it under the straps before tightening them. Works fine. http://i1282.photobucket.com/albums/...pskefvem2i.jpg The electrical wires from the motor fitted just in between the curvature of the motor and the tank holder http://i1282.photobucket.com/albums/...pseelsgbxz.jpg View of the back side of the Valve box http://i1282.photobucket.com/albums/...psn1asz1mg.jpg That brings us back to the hose I mentioned before ... Good thing I checked, as it turned out that I had swapped the 2 hoses. So had to take the whole thing out again and move those 2 from place. Of course they had to be the ones I installed first. Anyway about 15 minutes later... much better. http://i1282.photobucket.com/albums/...psl4iqvrlt.jpg And since I was at it, here the pictures of the return line I forgot to take http://i1282.photobucket.com/albums/...psui6uhvma.jpg http://i1282.photobucket.com/albums/...psqo7ywjre.jpg Now I have to figure out how to run the electrical wires to the front and sort it out on that end. This might take me some time. Stephan |

Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
Hi Al, you're in luck .. didn't think I would have the time today to work on the truck.
Well, spend yesterday evening a couple of house googling images of roll on/roll off kipper, abrollkipper, haak kipper and whatever language variation I came across. All this to see how other people run their hydraulic line from the pump. Not much to be found though. Found 2 who ran underneath and 2 who went up and over. So guess what ... decided to do the whole connection to the valve block again. I had left some of the lines too long being worried of getting them too short. New direction pressure line http://i1282.photobucket.com/albums/...pseprrwgom.jpg Top view http://i1282.photobucket.com/albums/...psmjia7k4w.jpg Side view http://i1282.photobucket.com/albums/...psikotrvxh.jpg In the course of redoing the connections, I had seen that the hose from the small cylinder tucked away behind the valve box had a kink in it. I feared I would have to take the whole lot off, but succeeded in removing the nipple, and replace the hose without unbolting anything else. Just enough room to go in from the top. Getting the nipple back on after replacing the hose was a true "zen" experience. http://i1282.photobucket.com/albums/...ps3za32nfj.jpg Shoved the + and - wire of the pump in a shrink hose and ran it to the front. http://i1282.photobucket.com/albums/...psmuib7vvb.jpg Since the servo wires are way to short, decided to see if I could fit an extension wire so it would be easier to make a repair at a later date. Inserted a 6mm shrink tube in-between frame and motor and behind the rear diff servo. This would allow me to pull 2 extensions through after removing the plugs. Couldn't get it to work in a decent way. The bowden cables from the rear diff locks and their servo are hampering anything on the chassis beam there. http://i1282.photobucket.com/albums/...pstsvwfwjj.jpg So tried to go the other way ... also didn't work. The connector is just too big. http://i1282.photobucket.com/albums/...ps14sdcdc3.jpg So soldered it together staggered to prevent the big clump when they are all soldered in the same place. This way don't have to worry too much about them shorting on each other either. http://i1282.photobucket.com/albums/...psv4mzzldf.jpg Still add some of the liquid rubber since I have it anyway. http://i1282.photobucket.com/albums/...pspx7x8jzg.jpg Wires from servos fixed and valve box ready to be closed. http://i1282.photobucket.com/albums/...psksgr7qd3.jpg http://i1282.photobucket.com/albums/...psyvfepos7.jpg Sorted (also retouched the paint a bit) http://i1282.photobucket.com/albums/...psgklne4z3.jpg All electrics are now in front, so next is my least favourite part of this build: the electronics and wiring, although I can still do the fenders first :p Almost forgot, I have put the side under run protections in such a safe place I can't remember where I put them. :o Cheers, Stephan |
Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
Here a pic of what needs sorting ... actually is not THAT bad (I hope) but those cables from the cabin have to somehow join here. (Already happy I paid the extra for the Bus system, saves a lot of wiring!)
http://i1282.photobucket.com/albums/...psgxpghhui.jpg Stephan |
Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
Found the side under run protection.
just have to be careful to have them in the right position and to stick the little pin in the right hole. http://i1282.photobucket.com/albums/...psfuqdxsmx.jpg http://i1282.photobucket.com/albums/...psjvvpq2ac.jpg http://i1282.photobucket.com/albums/...psqrsun1ci.jpg http://i1282.photobucket.com/albums/...psbhcv0pij.jpg http://i1282.photobucket.com/albums/...psiz5lwlbv.jpg Haven't fixed it to the chassis yet. Will first sort out the wiring to get this thing running. Till then Stephan |
Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
Wow! What a entanglement of wires, and not a lot of room. Still you are doing a great job..Can't wait for the next installment...
Alan |
Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
Hi Al, lots of wires, but actually compared to the "before Kingbus" era, it's not that bad ... Before you would have all the wires from the individual LEDs and miniature lamps. Just imagine having another 20+ wires :eek: ... Seen some pictures on the German forums that give me nightmares.
Wasn't going to post until I got a working or partially working project, but would be too many pictures - already have to split this up. So here goes - a dry run on how to install this stuff. Part 1 Before you can mess with the wiring, you need to build the box that will hold all the various bits - this in itself another marvel of engineering. (I must sound like an advert for them, but you really have to handle this stuff to appreciate the meticulous attention details) http://i1282.photobucket.com/albums/...psjvhkxc8k.jpg http://i1282.photobucket.com/albums/...psgyj64h4g.jpg http://i1282.photobucket.com/albums/...pslbzc9hyj.jpg http://i1282.photobucket.com/albums/...ps9cmgeffu.jpg http://i1282.photobucket.com/albums/...pse3almzip.jpg Later in the game I found that the long screw on the right in the picture should be about 1/2mm more to the right. These screws will hold the board which all the connectors for the power. http://i1282.photobucket.com/albums/...psfsn9mpvg.jpg Next the wire that connects the cab electrics (a detailed color code is provided) http://i1282.photobucket.com/albums/...pswzjvvmf0.jpg An approximation on how to install it all according to the manual. (The manual provides alternatives for those people who don't use ScaleART stuff) http://i1282.photobucket.com/albums/...pslyrxdfjt.jpg Lid goes on top http://i1282.photobucket.com/albums/...pseqos9lcs.jpg Battery in place http://i1282.photobucket.com/albums/...pserbr4qli.jpg |
Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
Part 2
Now time to try this on the truck with all the wires. At this point I didn't know what to do with all the wires, so I just shoved them randomly through the openings. What I noticed immediately is that, yes you can probably get the bottom plate on the chassis, but it sure interferes with the front lock/kip mechanism from the cab. Ended up trimming some from that area. http://i1282.photobucket.com/albums/...psgj3bgz7x.jpg Forgot to take pics after cutting the bits of. So here some I took later. Trimmed bit on the left side of the truck - could have trimmed of a bit more actually http://i1282.photobucket.com/albums/...psk0wspgos.jpg Right side - had to trim at an angle because of the shape of the holder for the flat cable connector http://i1282.photobucket.com/albums/...psuzdpjbgk.jpg Then on with installing it and bolting it to the previously installed holders. Here the screw that is 1/2mm out comes into play. I already filed out the hole (needed to move the screw a bit to fit the connector board) but apparently not enough. I had to file a bit off the holder too. http://i1282.photobucket.com/albums/...ps1ydtx6ga.jpg http://i1282.photobucket.com/albums/...ps21j7bbhf.jpg Once these 2 problems are sorted, the rest just fits perfectly. Those screws "click" in those holes with authority. This just makes you forget the 2 previous imperfections. (Kind of reassuring to know not everything is perfect :) ) http://i1282.photobucket.com/albums/...psrdf9khqn.jpg Fits nice and flush to the locking mechanism of the cabin http://i1282.photobucket.com/albums/...psrnqe20gb.jpg The idea is to feed all the cables through the opening under the electrical board, however some of my Servo wires would be too short (should have made the extension from the hydraulic valves 1 inch longer) to reach the receiver. This also creates a rather big mess in the area where the ESC is supposed to go. So decided to cut a small bit of the board. (Nothing there anyway) http://i1282.photobucket.com/albums/...psjsmpgh7t.jpg Then, why not ... an ever bigger hole so I can get all the wires through except the Kingbus from the rear lights and the power from the pump. http://i1282.photobucket.com/albums/...psm9mylird.jpg Here all servo wires connected. Some are way too long. Need a crimping tool and plugs to shorten them (ebay to the rescue). But will do for now. http://i1282.photobucket.com/albums/...pssljtk3ns.jpg The cabin connector/cable installed and checking placement of the ESC and BEC. Lots of room really. Had to cut of on of the "feet" of the receiver to accommodate the ESC. http://i1282.photobucket.com/albums/...psyoxkxqix.jpg The flat cable split up for cutting/connecting http://i1282.photobucket.com/albums/...psrieomjl9.jpg So that's where we are at the moment ... is 8:30 am here so maybe I can finish today. Stephan |
Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
Part 3
Cut some cables and soldered some others. Folded excess servo wires as best as possible until I can shorten them. http://i1282.photobucket.com/albums/...pspbcwzjcf.jpg This one goes nowhere so gets cut. (I actually asked the guys at ScaleART months ago about it) http://i1282.photobucket.com/albums/...psbuq0gyiq.jpg Same for this one, 2 are for sound if speaker is the in exhaust, other two not used. Haven't cut this one yet. http://i1282.photobucket.com/albums/...psuzxzq8o9.jpg Installed cover, plugged in battery, couldn't lock cab until I bend the wires from the battery down. http://i1282.photobucket.com/albums/...pshwgfxqdw.jpg Tested and everything works except, the left rear light the cats played with and http://i1282.photobucket.com/albums/...ps5xgmacmp.jpg http://i1282.photobucket.com/albums/...pstxq8nvp9.jpg one LED at the front is kaput ... High beam, foglight and other other bits work http://i1282.photobucket.com/albums/...psiynmk6yk.jpg except for the regular head light http://i1282.photobucket.com/albums/...psuaclhkqz.jpg I must have bumped the corner somehow somewhen. See paint damage. This must have put stress on he LED board what probably caused the damage. http://i1282.photobucket.com/albums/...psh5h3x2ys.jpg Will also have to look into the power to the cabin ... somehow the sound isn't working nor the indicator and stand lights. (mhmm ... must be my brilliant soldering) For the rest things are good. Haven't yet put in the oil, but I know the pump and servos are working. So looks like I'm ordering new rear and front LEDs. By the time those arrive, I will have the crimping tool too. So will redo the whole lot at the same time. Nice thing with the Kingbus system is that I just have to unplug the faulty one and plug in the new one. No wires to cut solder and what not :) http://i1282.photobucket.com/albums/...pszrrgttjc.jpg Cheers! Stephan |

:o :o :o Oops ... reason no power in cabin and no sound ... forgot to plug in the connector :rolleyes: Another senior moment.

Really loving the daily updates and what we could expect it we brought a ScaleArt kit very informative.
Cheers Tracy |
Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
Hi Tracy ... now it will be trouble shooting though.
Even when cab connector plugged in no sound and no lights. :confused: Green LED sound module is blinking but that's about it. Maybe I plugged something in wrong way round or so. Not the end of the world really. As for the indicators and stand lights not working, I have to check my wiring at the "Universal Kingbus module" inside te cab. On the other side, the LEDs at the headlights are all working now. Must be a bad contact inside the board. Plugged the left rear light in the right rear plug and no joy, guess it is truly toast. Meanwhile finished the fenders and attached the under run protection (absolute pain that one). Will update that tomorrow. Cheers! Stephan |
Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
Great update Stephen. Now that you have giving me my fix for the day, I can continue the rest of my day..

Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
Hi Al, your fix?!? :) I'm getting worried about my daily fix here ... Almost finished (apart from sorting out the niggle with the SMX and the rear light) and already suffering from withdrawal symptoms ... This kit is strangely addictive. Already been looking at the ScaleART shop and convincing myself that I can afford another one ...:p

Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
Here the pictures of the fenders I installed yesterday:
Left front fender first http://i1282.photobucket.com/albums/...psgvkm0g2v.jpg Per the manual cut a slot for the steering rod that runs on the left http://i1282.photobucket.com/albums/...psitshg36a.jpg Then shove over the support. The rear wouldn't go in all the way to the stop due to the screws holding the suspension to the chassis http://i1282.photobucket.com/albums/...psds1fav3l.jpg A rather big hole is required as the nut needs to fit too. (Looking at the picture, it ooks rather messy from the inside :o) - Same on the right side too of course. http://i1282.photobucket.com/albums/...psdiuednhp.jpg Next rear fenders. They get screwed together as they use same middle support. http://i1282.photobucket.com/albums/...psyuwbucdf.jpg To make sure they lined up, I put 3 M1.6 screws through the indicated holes that are there for the mud flap. Where to drill is indicated on the parts http://i1282.photobucket.com/albums/...pstlkiow63.jpg Install generic mud flap http://i1282.photobucket.com/albums/...pshxbavnyz.jpg Needed some trimming - Reason: see box in picture above with the holes indicated. Due to the form of the fender one bolt is close to the edge. http://i1282.photobucket.com/albums/...psrxah26sa.jpg Also needed to file one of the sides of the washer so it would fit in the small area available. http://i1282.photobucket.com/albums/...pspeehzqsj.jpg http://i1282.photobucket.com/albums/...pscrhrcg0p.jpg Before installing run a 4mm drill through the holes to remove the small bits of plastic that might still be there from the casting. I also put a bit of silicone grease on the plastic to make it a bit easier to slide them on. http://i1282.photobucket.com/albums/...ps1ol7eign.jpg Next the under run protection ... this was a real pain. On the side of the oil tank the support touched the tank, considering the length of the screws that were with the part, figured an extra nut near the frame was in order. Up to there no problem. When trying to bolt the actual unit to the frame ... could not get a tool in there. Had to fasten the nuts with tweezers and only at the very end could use a 3mm spanner. The 2 at the bottom were an even bigger challenge. Took forever. - Hence no pictures of this ordeal. http://i1282.photobucket.com/albums/...psfpewhlsm.jpg Looking at it, I think I will take them back off. Liked it better without them. http://i1282.photobucket.com/albums/...psdwj9qhzr.jpg http://i1282.photobucket.com/albums/...psm3m3wjq4.jpg Stephan |
Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
Got the rear light to work - so it survived the cats dragging it around. Checked the plug and even though I marked it when I took the plug off I swapped the + and - ... :confused:
Checked the pictures I took and then the actual wiring (without taking the cab apart) on the sound module and all according to the manual ... stumped on that one. Still have to check the indicators and stand light on the cab. http://i1282.photobucket.com/albums/...psmfnescgd.jpg |
Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
Not a happy camper ... started to prime the oil pump and found out one of the valve servos is not responding. Must have broken a soldered joint in the extension down the line. So repairs needed.
The other servo controlling the kipping is working fine, but even after 5 minute running the pun and moving valve back and forth no movement to be seen ... lots of gurgling going on in the oil tank though. To make things worse, the battery in the truck ran down, tried to charge it, and the on-board plug is not accessible due to the hydraulic cylinders ... http://i1282.photobucket.com/albums/...pslgn0ryhp.jpg Meanwhile, got the raised exhaust up. Painted it black and have the pipe disappear under the cabin so it looks like the actual exhaust is under there somewhere http://i1282.photobucket.com/albums/...pstv3yzrwg.jpg Well that will be it for a while. Until I find a way to make a 2nd plug on the battery so I can charge it, nothing much can be done. Guess I can start on the container. The last part that needs assembling. |
Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
YES! Hydraulics work. Succeeded in getting a charge out of the battery. I put a spare nipple on a piece of hose and screwed it in the pump. Found out that the pump was sucking instead of pumping oil out. So changed the direction of rotation in the transmitter. Had just enough juice to see the mechanism go up. So much for trusting the pre-programmed settings you get with the Commander :)
So tomorrow have to find out why the other servo isn't functioning. Hopefully just a broken connection. |
Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
Now I know why I have stayed away from hydraulics :eek::eek: You have a lot more patience than I every thought about having. Even with a degree in electronics, this end of the hobby simply makes me loose my mind. Hope you find all of the problems quickly and easily.

Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
Congratulations Stephen!! I'm getting as much joy as you are in this build..
This project is turning out great !! Alan |
Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
Well done!
On the charge port, I would suggest checking if you can get a right angle plug of the same size... Typically they are a bit shorter... On the sound, I am sure you will get it sorted, more than likely it is something simple... Wrong plug or wrong direction etc... There are lots of wires in these things... It's really easy to get a couple wrong first time around! :-) Let us know if you want us to review how it is connected... Pics and diagrams will make that relatively easy... Cheers, Ap |
Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
Ahhh...
Just looked at your jumpers on the SMX... Check the manual, on the bottom of page 9... I think you have the smx in setup mode... If you haven't changed the jumpers since you took the photo... In post #108... Cheers, Ap |

Give me hydraulics over electronics any day! ... when they don't work it's either a blockage, a bad valve or bad pump - at least at the simple level employed in these models. You should give it a try. Only thing is that the oil seems to get everywhere ... |
