Part 2 - connecting the 2 parts of the hook mechanism.

The parts

http://i1282.photobucket.com/albums/...ps36k3tggb.jpg

Per the manual, apply some grease where the bushing will fit

http://i1282.photobucket.com/albums/...psraaxmulf.jpg

Space and bushing in place and then bolt to the already finished frame. A very precise fit by te way.

http://i1282.photobucket.com/albums/...psxafxvnca.jpg

Both connected and shown with the parts needed to work the sliding hook and connect it to the truck chassis

http://i1282.photobucket.com/albums/...psmvoeidja.jpg

First the pull/push rod

http://i1282.photobucket.com/albums/...pshey6otcd.jpg

Then grease applied where the bushing will go.

http://i1282.photobucket.com/albums/...psrnplzjqa.jpg

The part that will attach it to the frame installed. The holes indicated is where the bolts will go that hold it in place.

http://i1282.photobucket.com/albums/...psknnrsodv.jpg

When used as a kipper, this whole assembly will move up and the hooks will slide out to secure the container.

http://i1282.photobucket.com/albums/...pssgtxagij.jpg

You can see I put the hydraulic lines above the cross brace. Will have to move them below, they might get clamped when using in roll off roll on mode. (getting the hydraulic lines through the guides was made easier by applying some grease to the guides)

http://i1282.photobucket.com/albums/...psw9cvn9re.jpg

Both sides done

http://i1282.photobucket.com/albums/...psdg0zxkml.jpg

Quick look for fit on the rolling chassis

http://i1282.photobucket.com/albums/...psnmawy3ky.jpg

And the why of those 2 little bits installed in the beginning. And no, I did not forget to put a nut on the naked bolts :)

http://i1282.photobucket.com/albums/...psawjqfxmp.jpg

That's it for the moment.

Correction on the locking part of the hook. Apparently I installed it wrong way around.

Here corrected:

Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
 

Found some time to add some small parts to the frame, namely the bits that hold / lock the driver's cabin in place.

Here the parts - all in stainless:
The 2 big hooks at the bottom are for the front.

http://i1282.photobucket.com/albums/...pss2iw0pz0.jpg

First one to go in. This part

http://i1282.photobucket.com/albums/...pssvclun0c.jpg

Goes here on the right side.

http://i1282.photobucket.com/albums/...psvpmdfklm.jpg

Loctite applied to the nut. This part needs to stay moveable.

http://i1282.photobucket.com/albums/...psyi6clo0t.jpg

The second part

http://i1282.photobucket.com/albums/...psskhuqric.jpg

Goest on here on the left side

http://i1282.photobucket.com/albums/...psvojvipz5.jpg

Here too loctite on the nut so the handle stays moveable.

http://i1282.photobucket.com/albums/...psninxqt7g.jpg

Next up the bar that connects these 2 parts. (spacer nuts already in place)

http://i1282.photobucket.com/albums/...pslqjmnpab.jpg

Loctite here too.

http://i1282.photobucket.com/albums/...psvszx8drx.jpg

Finally the spring to keep it in locking position.

http://i1282.photobucket.com/albums/...ps0xwa0nff.jpg

Now the front.

Hook goes here

http://i1282.photobucket.com/albums/...pswplu2w9k.jpg

Here too loctite on the nut/bolt that holds it attached to the frame. Tightened so the handle can still move forwards and back.

http://i1282.photobucket.com/albums/...psnl7sshib.jpg

The spring is kept in place by the thread on the bolts.

http://i1282.photobucket.com/albums/...psqkfttqyj.jpg

http://i1282.photobucket.com/albums/...pstvfc78dz.jpg

That's it for now. Might be another couple of days before the next update.

Cheers - Stephan

Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
 

So many pieces!!! Lovin it.

Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
 

Hi Stephan,

this is a awesome model. You will have also many fun while driving it. - And your building report is very detailed. I love this kind of reports as you know well. - Go on, I´ll stay tuned. ;-)

P.S.: Please excuse my mistakes. My English is not very well. I´m working on it.

Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
 

me and the china kat are not talking right now,its got its
back to me right now.
this truck looks like it will be unstopable when done

Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
 

Hi Christian, nice to meet you here :)! Glad you like the build report. And your English if better than my "Google German" as you can see below!
Of course I know you like detailed build threads! It’s yours on Modelltruck.net that got me into this! :)

For the moment we have a pauze because I’m waiting for a package from ScaleART (shipped May 27th) with the updated parts of the cab, the raised exhaust and some nipples for the hydraulics.

I could start on the container, but I keep that for when the truck is almost finished (meaning I'm struggling with the wiring :confused: ) as something to keep me from getting to frustrated. :D

Cheers! Stephan

============================

Hallo Christian, schön dich hier zu treffen :)! Gut, dass dass Baubericht dir gefällt. Und Ihr Englisch ist besser als meine "Google Deutsch", wie Sie hier sehen können!

Natürlich weiß ich, wie Sie detaillierte bauberichten liebst! Es ist wegen Ihrer auf Modelltruck.net die mich motiviert haben! :)

Am Moment haben wir pauze. Ich warte auf eine Paket von ScaleART (versendet 27/05) mit einige Teilen von die update das Fahrerhaus, der hochgezogen Auspuff und einige Nipple fur die hydraulische Leitungen.

Ich konnte natürlich mit die Mulde anfangen, aber ich warte bis das Model fast fertig ist. (Wenn ich mit der Verdrahtung kämpfe :confused: ) Denn dan habe ich noch etwas einfach um mich von Frustration zu halten :D

Gruss! Stephan

Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
 

Now that is funny! Hope you get on talking terms soon! Been keeping my eye on that thread.

Stephan

Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
 

Hi Stephan,

as I can see, you´re using the new 2-wire-bus system for the light-functions. I think, there won't be any problems with it. You'll manage it easily. - So go on with the container! - Have fun! ;)

Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
 

Hi Christian, yes, I do have the Commander bus system, but you haven't seen the mess I made of the electrics in the 490LC :roll eyes: . I was thinking of sorting that out while I wait for the parts to make their way halfway around the world.

Cheers, Stephan

Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
 

A small update. Prepped the front lights for fit of the LEDs. Not a big job but at least it is out of the way.

Checked the tracking I got and the package from ScaleART has cleared customs in Kuala Lumpur. So now waiting for it to make it here. With some luck might get here beginning next week so we can get on with this.

Here the housing with the LED board. You can see that some of the openings are not completely open.

http://i1282.photobucket.com/albums/...psqrhvg0kj.jpg

Trial fitting showed that the circled opening was too narrow also.

http://i1282.photobucket.com/albums/...psqybmyxee.jpg

Tools used for "fixing" the smallest drill bit in the Dremel collection (1/32" for the Americans) and a small round file.

http://i1282.photobucket.com/albums/...psntpwdgbe.jpg

http://i1282.photobucket.com/albums/...psuhrtks2t.jpg

2 twists with the file and perfect fit.

http://i1282.photobucket.com/albums/...psogrpz6n2.jpg

http://i1282.photobucket.com/albums/...pso0ylhh9f.jpg

Both sides had same treatment.

Since I got them and for completeness sake, here a pic of front and back of the PistenKing LED boards

http://i1282.photobucket.com/albums/...psbbvrfna8.jpg

Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
 

The raised exhaust etc. arrived 2 days ago. Today found time to install it.

Ordered the raised exhaust because there is no room for the Euro 6 one on this model. By putting up the raised exhaust at least I have an indication of one. Bit weird having a model without exhaust.

So here the bits. Will only install the support for now. The rest would just be in the way during assembling the rest of the truck. Will also have to come up with a way to pretend the exhaust goes under the cab. The curved bit supplied will not do for the purpose.

http://i1282.photobucket.com/albums/...pspvl1fs1m.jpg

Bolted the little piece to the main upright before painting. Such a little piece would be too much of a hassle.

http://i1282.photobucket.com/albums/...psrowjtumf.jpg

Main upright first. Goes here. Will have to replace 3 bolts with longer ones.

http://i1282.photobucket.com/albums/...pssoqykaev.jpg

Bit fiddly but got it in place.

http://i1282.photobucket.com/albums/...psu5kotmgi.jpg

Other side goes in similar spot.

http://i1282.photobucket.com/albums/...ps05pjbipr.jpg

Before install bolted the crossbar to it. Would have no access afterwards.

http://i1282.photobucket.com/albums/...pskn1rcwey.jpg

And here I ran into a fitting problem! ... The frame from the hook mechanism is interfering.

http://i1282.photobucket.com/albums/...pskmt1xkqt.jpg

After some diligent and careful filing/fitting and a bit of paint.

http://i1282.photobucket.com/albums/...psmstztfab.jpg

Got it to fit. (also filed the bottom nut down at an angle)

http://i1282.photobucket.com/albums/...pstwhzqjey.jpg

Installed. Will replace the screw holding the crossbar to the main upright with a M2 model bolt.

http://i1282.photobucket.com/albums/...ps32bt82yj.jpg

Had hoped for some more progress, but between the filing and waiting for paint to dry ...

Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
 

Drivetrain - Part 1

Started with the transfer case.
The support gets M2 nuts as spacers to the frame.

http://i1282.photobucket.com/albums/...pslagtibye.jpg

And it attaches here

http://i1282.photobucket.com/albums/...psmgisbkwb.jpg

The transfer case comes with 3 M8 screws in place that need be replaced with M10 ones.

http://i1282.photobucket.com/albums/...pshwnbcc0m.jpg

After initialling the spacer nuts on the support, I tried to fit it, but ran into difficulties ... Remember I had moved one of the tank supports one hole to the right. It now interferes with the support.

http://i1282.photobucket.com/albums/...psbs6wo8xb.jpg

After replacing the M8 screws on the support with one with a smaller head, and grinding a bit off the one holding the tank support, it fitted. Easy solution.

http://i1282.photobucket.com/albums/...psjpqgbu8i.jpg

Support in place

http://i1282.photobucket.com/albums/...psrgfh3gm1.jpg
Transfer case screwed on.

http://i1282.photobucket.com/albums/...psfljsa6np.jpg

Next the motor/gearbox

The motor has a thread and screws into the gearbox. It is held in place with a grubscrew.

http://i1282.photobucket.com/albums/...psuj1ddu6x.jpg

http://i1282.photobucket.com/albums/...pss1tjsk3k.jpg

In the kit they supply a support for the motor/gearbox. (the big stainless contraption) This is not needed in this truck since the support is part of the frame of the hook mechanism.

Luckily for me I remembered reading in Christian's (Newcomer_2) thread on the German forum that for this truck you need to use a special spacer (the small rectangular bit) which comes with the hydraulic parts.

Because this spaces is about 3mm thick, I replaced the recommended M2x6 countersunk screws with M2x8 ones. Have to be careful because the hole circled in red. You can block the gears if you get too long a screw in there.

Because the frame I have is not foreseen for countersunk screws, used regular ones.

http://i1282.photobucket.com/albums/...psnrfkete0.jpg

http://i1282.photobucket.com/albums/...pslwqtmwi9.jpg

Installing this unit with that spacer "floating" around was an absolute pain in the neck ... but eventually I got it sorted. According to the instructions, the motor needs to be grounded to the frame.

http://i1282.photobucket.com/albums/...psbhbtjldf.jpg

Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
 

Drivetrain - Part 2

Now the props hafts

First the one from the gearbox to the transfer case.

http://i1282.photobucket.com/albums/...psnfeuch5e.jpg

And then the rest. First did the front axles starting from transfer case, and then the rear axles starting from transfer case. The grubscrews have been generously applied with Loctite.

Incredible!! Keep up the good work and progress pictures..

Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
 

Hi Alen, I'm working on it :) Putting this thing together is addictive in a weird kind of way.

++++++++++++++++++++++++++

Now we getting to the parts that are not amongst my favourites.

Installing the cluster of servos for the transfer box lock, steering and gearbox.

http://i1282.photobucket.com/albums/...ps0axvvd9z.jpg

Starting with the biggest one, steering servo.

http://i1282.photobucket.com/albums/...pskwz4gbpb.jpg

Installed and bits for the bowden cable attachment laid out.

http://i1282.photobucket.com/albums/...psa4taqmem.jpg

http://i1282.photobucket.com/albums/...psbugfd0x6.jpg

At this point I figured I'd better centre these things. Rummaged around till I found my servo tester and started out centring them all. (I also did the ones already on the truck)

http://i1282.photobucket.com/albums/...psesircfcy.jpg

Next up the 2 smaller ones. Right the one for the transfer lock, left the one for the gearshifts.

http://i1282.photobucket.com/albums/...psfubhoc8g.jpg

First the gear shift servo goes in. Only gets fastened on one side at this point. The other side gets fixed together with the other servo.

http://i1282.photobucket.com/albums/...psarm2hnuz.jpg

And all three installed. Had to remove the holder for the bowden cable to get the last servo in place. Easy to do and re-install.

http://i1282.photobucket.com/albums/...pswdobp0ag.jpg

Then the whole assembly slides into the front of the frame and gets attached with 4 M2 screws. (All the holes in the frame holding the servos are threaded)

http://i1282.photobucket.com/albums/...psa6yruwo2.jpg

I had done a trial fitting before, and the power cables of the motor had to be bend out of the way. Very tight in there.

http://i1282.photobucket.com/albums/...psjgqystjg.jpg

Bit tricky too as the assembly has to be shoved in between these 2 rows of screws in the frame.

http://i1282.photobucket.com/albums/...pskkicneji.jpg

Assembly in place (but not yet screwed on)

http://i1282.photobucket.com/albums/...psyafqkdf3.jpg

View from below after screwing it in place

http://i1282.photobucket.com/albums/...psmgfqbpta.jpg

View from the front

http://i1282.photobucket.com/albums/...psdqpts9sy.jpg

Next will be trimming the servo horns, doing gear box link, steering link and the bowden cables for the diff locks etc.

Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
 

Spend time on the transferbox lock.

The steel cable goes into a teflon one that goes into the metal guide ... Here a picture of what I'm talking about. (just for show)

http://i1282.photobucket.com/albums/...psotq4knof.jpg

Cutting the servo horn and drilling the 3rd hole out to 2mm etc.

http://i1282.photobucket.com/albums/...psetwdabrn.jpg

Decided to make the horn black with a Sharpie before I mounted it on the centered servo. (looks reddish in picture, but is black)

http://i1282.photobucket.com/albums/...psmdlcmnvm.jpg

Then I spend some enervating time figuring out how to run the metal tube. First I started out at the transferbox and worked my way forward, but that was a non working proposition because trying to get that flippin thing in the clamp near the servo is a nerve wrecking proposition ... Well anyway now had a good idea of how to fit it. So started from the servo and worked my way backwards to the transfer case. Shortened it there and gently clamped it in place with the screw. Then shove in the teflon hose, followed by the steel pull cable.

After I finished this bit, I took pictures of how I ran the cable.

Starting at the transferbox the cable goes towards the rear of the truck.

http://i1282.photobucket.com/albums/...ps4dc0gqrd.jpg

There it goes inside the frame through one of the holes provided and swoops 180° back towards the front. I have attached to of those clamps, but I drilled the hole out to 2.5mm to make it easier to get the cable through. It does not clamp the cable, just prevents it from flopping about.

http://i1282.photobucket.com/albums/...ps270k53iw.jpg

Installed a 2nd clamp (also drilled out to 2.5mm) just before the gearbox, and from there the cable swoops up to go over the gearbox

http://i1282.photobucket.com/albums/...psuy1ajbdi.jpg

And then down again to the clamp near the servo.

http://i1282.photobucket.com/albums/...psoqhufdxg.jpg

There the metal and teflon hose are cut to size and the steel cable is then tensioned and attached to the servo. I haven yet cut the steel cable to size because I might need to make some adjustments once I get the radio control hooked up. The red arrow points toward where the next step - gearshift - will attach.

http://i1282.photobucket.com/albums/...psuoo4nzgq.jpg

Gearshift - the parts

http://i1282.photobucket.com/albums/...pspuysndrm.jpg

Easiest to first attach the pull bar (tried some other approaches first)

http://i1282.photobucket.com/albums/...ps93qjfhuc.jpg

And then mount these bits. The clamp attaches to the servo horn pointing downwards. They show it mounted both ways in the manual.

http://i1282.photobucket.com/albums/...psrfq6apiw.jpg

Installed. There is a mark on the bit sticking out from the gearbox that indicates 2nd gear. (This is installed with the box in second gear) The springs are supposed to be only lightly compressed. (careful, I spend about 10 minutes looking for the one that sprung away)

http://i1282.photobucket.com/albums/...psfd4y4jr4.jpg

And last the steering linkage

http://i1282.photobucket.com/albums/...psa8x6zblm.jpg

http://i1282.photobucket.com/albums/...psecegmfp8.jpg

Now next would be the bowden cables of the diff locks of the axles. Hope they go in easier than the transferbox one.

Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
 

After yesterday's trouble with the bowden cable I was prepared for another ordeal. However it all turned out to go rather easy.

First attach the bowden pull tube to the axle and guide it to the clamps that were installed way back and guide it through the frame to the clamps near the servo.

http://i1282.photobucket.com/albums/...psgtvyzeur.jpg

http://i1282.photobucket.com/albums/...pspfgcnlgo.jpg

http://i1282.photobucket.com/albums/...psocsu0f1j.jpg

http://i1282.photobucket.com/albums/...pskfl0m2gk.jpg

Then insert the steel cable, make sure it moves smoothly. Then cut bowden pull cable to size.

http://i1282.photobucket.com/albums/...ps4iv3pgbw.jpg

Attach steel cable to the puller on the axle - I used a loop there before I put in the screw - and push cable till it comes out at the servo. (If I do this again, I will insert a screw in there before I even mount the axles to the frame. Saves a lot of fumbling)

http://i1282.photobucket.com/albums/...psrdftl5km.jpg

For those who wonder how the bowden is clamped in place on the axle:

The hole through which the tube goes is attached with a screw. You have to loosen this one a bit so you can push the hose through. Afterwards just tighten a bit and hose is clamped in place without being crushed.

http://i1282.photobucket.com/albums/...pse5tqabuo.jpg

http://i1282.photobucket.com/albums/...pshgzj8dwb.jpg

The next axle is same procedure

http://i1282.photobucket.com/albums/...psnwwggeud.jpg

I first tried to run the pull cable through the indicated hole in the frame, but that just complicated things. So went straight to the previously installed clamp.

http://i1282.photobucket.com/albums/...psjoyejkal.jpg

http://i1282.photobucket.com/albums/...psunxls0jo.jpg

Tensioned up and eft some extra for possible later adjustments. Cut all the cable ends shorter and added a dab of crazy glue to stop fraying.

http://i1282.photobucket.com/albums/...psvhqic8vv.jpg

Was going to stop here, but then noticed that the left over bits from the rear axles were more than enough to do the front ones too. (so still have a complete set of cables from the front axles that should sufficient to redo the lot) Again same procedure, but routing is way simpler. (did have to take of the steering linkage for the 2nd axle to be able to get the the screw that allows the cable to be attached to the axle. Since it was off I also adjusted the tracking that was a bit off)

http://i1282.photobucket.com/albums/...psu1hvdml4.jpg

http://i1282.photobucket.com/albums/...pszim223du.jpg

On a side note ... when I installed the motor/gearbox I left the cables from the servos dangling where they were ... not a smart move. Took some fiddling to get them where they belonged.

http://i1282.photobucket.com/albums/...psuvhrxkme.jpg

Well, now is the time to get out the remote control and start fine tuning the servos and checking gearshift and steering before I start on the driver's cabin etc.

Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
 

Spend time sorting out the settings. Lucky the RC is pre-programmed by ScaleART for their models. Saves a lot of time. Just pick the variation you want and you got the basic settings.

http://i1282.photobucket.com/albums/...psw1yqv8in.jpg

Of course they still need a bit of fine tuning.

http://i1282.photobucket.com/albums/...psyakw1f1j.jpg

Had a bit of a problem with the ESC ... took me a while to figure out how to do it. First spend time looking for the jumper before I realised it was already on the ESC although on the wrong pins. Then couldn't get the jumper off the pins so I could move them to the program pins to "marry" the ESC to the Sender. Had to cut the heat shrink off. Also having the instructions in technical German was a tad confusing ..

http://i1282.photobucket.com/albums/...pshowgmruc.jpg

Well got it all sorted

Just one little problem ... mixed up the plug position from the trailer coupling servos with that of the gearbox servo and succeeded in burning out the one from the gearshift ... Lucky the one from the trailer coupling in the back is the same. So guess I will have a manual trailer coupling until the new servo I ordered arrives.

Meanwhile the truck has moved under its own power. Now just sort out some little niggles in the servo settings. Like why the front diff lock servo locks the diff when I turn on the power etc.

Re: Scaleart - assembling an Arocs 8x8 roll on roll off kipper
 

I was lucky that to replace the fried servo I did not need to take the whole contraption out of the frame. Was a bit tight, but succeeded in doing it without major surgery. Before I replaced the burned on with the one from the trailer coupling, I followed Propshafts method of cutting off a bit of the rubber around the wires. Made it much easier to get the screw in, and as an added bonus I can now get the wire away from the servo horn of the centre diff. (So thank you Propshaft!)

http://i1282.photobucket.com/albums/...psrxk8d8jq.jpg

Just look at the difference.

http://i1282.photobucket.com/albums/...psfrdpymfe.jpg

http://i1282.photobucket.com/albums/...psmdlcmnvm.jpg

So that's one very burned servo ...

http://i1282.photobucket.com/albums/...pschmbjoqe.jpg

http://i1282.photobucket.com/albums/...psjecyhrth.jpg

All because firstly, I was so stupid not to label the plugs correctly, and secondly I didn't check the numbers on the slots small as they might be ... Lesson learned.

http://i1282.photobucket.com/albums/...psvwwzapet.jpg

Guess the servo burned out because the trailer coupling was set for the full 100% sweep, thus keeping the servo trying to reach its endpoint.

All that is sorted now. Made easy peasy with the Commander Sender. Here adjusting the rear diff lock servo. Only needs about 50% of it's travel to be locked.

http://i1282.photobucket.com/albums/...psofcihtlb.jpg

And the problem with the servos of the centre and front was just reversing the directions of operation.

http://i1282.photobucket.com/albums/...pslh8tzsi5.jpg

So all servos now have their limit of travel set, so no more buzzing or juddering anymore.

Then check the tension on the pull cables and trim them to size. Adding a bit of crazy glue at the ends so they don't fray.

http://i1282.photobucket.com/albums/...ps2wd91kkn.jpg

The liquid electrical tape I ordered arrived yesterday. Going to use that to on the LED board of the rear lights instead of the home made piece of rubber.

http://i1282.photobucket.com/albums/...pssmokj9kw.jpg
