Post a pic of the bed next to my d11
Thats cat# 458-9587

Re: Great Dane excavating co.
 

I didn't want to touch the bed and sure didn't want to pick the dozer up next to it!!!

Light is casting a shadow onto both of them and the tank only has one coat on it but you can see the difference in old cat yellow (tank) and new cat yellow (dozer can)

Joe, finally got to pump, this is the number on it.

Re: Great Dane excavating co.
 

That's not it, that # would be Martin Kampshoff's stamp. The # I refer to is the # stamped right on the pump just above S P, it's sometimes very faint to see. The # on both these pumps is 4002 which is 0,30ml/revolution

Re: Great Dane excavating co.
 

Here is a suggestion to improve flow to your dump cyls, use 4mm fittings on the valve to a tee block, then 2,5mm fittings from tee to cyls. The 4mm fittings on valve need to be filed down to screw into place, just leave enough flat spot to snug with a wrench.

Re: Great Dane excavating co.
 

Originally Caterpillars were painted Gray up to the end of 1931 Then changed to "Hi-Way Yellow" December 1931 making them more visible on construction jobs.
Cat changed the old "Hi-Way Yellow" to the new present day gloss yellow between 1979-1984.
Main reason for was the old yellow had a high lead content which is now banned. The old paint lasted longer because of the lead though. I have restored several old Cats from the 30's that still retained the gray or yellow paint.

First coat on the frame.

Joe the number on pump is 4002. Now that I have everything apart I'm going to open things up a bit try and make bigger hose work and open up the fittings some. I'm feeding both those big cylinders with one valve and 4mm hose. Doesn't make much difference if I up the rpm on pump so I'm pretty sure it's a restriction issue with all the small fittings and hose. Thanks joe:).

Re: Great Dane excavating co.
 

Thats a few cans of yellow right there

Re: Great Dane excavating co.
 

What's the pressure set to? Higher pressure will dramatically increase flow... 250psi would be bout right.

Re: Great Dane excavating co.
 

Looking at the gauge now I think I was only running 100-125 psi, around 10 bar. So plenty of room to up the pressure,,,

Swapping out one of the 4:1 planets for a 3:1, increasing speed some. Trying to get up to 30 mph (1:1 scale) speed. Forget if I ever greased the other two planet gears, well it's apart so might as well clean and regrease. So I should end up with tranny being 3:1,3:1,4:1 then diff being 3:1 gearing reduction.

Re: Great Dane excavating co.

Here is the gearbox taken apart still have 5 of the 3:1 planer gears inside the ring gear yet , but you can see the size. Couple of you asked about gearbox, banebots is where I got it from , it is the p80 size

Re: Great Dane excavating co.
 

Well what can i say this post is amazing I have just read from beginning to end over the last few days.
Very high level of work and quality. You shouldbe proud of your work.

do you use any drawing programs 2d or 3d or whatever for when your building your projects? or just by hand?

Re: Great Dane excavating co.
 

Yup that pretty much is it, for the d11 and haul truck I did also purchase (off eBay) a shop manual. It shows some parts to get better idea of how they fit and work. My plans are just number jotted down on a notepad and some rudimentary hand sketches. But I have it all thought out in my head :). Lol!! That's why I end up with a few extra parts, ya know cut it twice and it's still short!!

Re: Great Dane excavating co.
 

That's a great idea I seen the model toy but the shop manual would be really helpful. Can't wait to see it once it's all together.

All parts painted with exception of having to hand paint railings. I didn't want to take them off as I might not get them back on:).

http://i1357.photobucket.com/albums/...psvgetclvg.jpg

And haven't seen this for a while!! Cleaned off and now ready to build her back up!! I did order some bigger smc fittings and need to make a splitter but no big deal for that. I went right to the source,

Smcpneumatics.com

Is the site that manufactures all the push to connect fittings. Cheaper to order from them and quicker than waiting for some from overseas. The site has all of them but you may have to go to the online catalog and find the part reference number because the pictures don't always match the part. I'll try and post this in the reference section for others also. Along with banebots.com for planetary gearboxes.

Re: Great Dane excavating co.
 

Looking great cannot wait to see the beast go back together its going to look amazing.

Re: Great Dane excavating co.
 

One thing to note is what hyd hose are you using... if it's what Premacon supplied you with, then it's burst pressure is well in excess of 500psi. From anyone else that might be a softer more flexible rubber hose, 250psi is right at or just below burst pressure.

I've used the plastic push connects in metric sizes at 20bar no problems.

Re: Great Dane excavating co.
 

I forget exactly what but the stuff I have is 350 or 400 psi? Been in use on the excavator for some time and I'm running close to 300 (I forget exactly maybe 275) , but no issues. Couldn't wait for premacon long delivery and $ so found some stateside :). The first time learning with hydraulics I did get about 25' (cheep) of stuff that would form a nice bubble as I was looking at it thinking boy that is weird,,, then pop!! Oil everywhere!! That stuff is still sitting around here somewhere!?!??

I did end up using a number size smaller on my seals of the third stage. They were leaking pretty bad. May have grabbed the wrong ones to start with,, at leas I hope so :). Not much room for error and all my tollarances have been pretty much trial and error. Hopefully I don't have to build new cylinders. If I do I'll know what I'm doing this time around. As there is always things to change improve on!!

http://i1357.photobucket.com/albums/...pszyqj6t1e.jpg

Forget if I mentioned this in thread before but I do have dust seals on the taper bearings used in the front wheels. Hub cap protects them on outside. Thanks to walmart, got the bearings from them, in automotive department, trailer wheel bearings ;)

Guess I wasn't really paying much attention to details, I installed this toggle switch for an on/off from battery. I didn't look at the amp rateing of switch and cooked it!! Also found out that my gearing change is too much for the esc/motor to handle. Thought I cooked the esc but it is still working. Went back to original gearing but esc still runs hot. But I do have a much bigger sensor based esc that I'm swapping out to see if that will run cooler. When we were at the last show the truck took off instantly on its own and that may have had something to do with esc malfunctioning. Glad it wasn't pointed at anyone's trucks, it ran into a cardboard box against wall!!!

Also dismantled lift cylinders for inspection and found some scratches on cylinders. Dropped a size on the orings for second stage and re polished. Put back together and left side kept leaking. Right side was good so at least I was doing something correct :). After cycling them a few times the leak stopped and they are working rather well. No excessive oil on cylinders and nothing leaking out!!

Today,,,, working on computer stuff, today I'm am the I.T. Guy,, even brought my best computer tools. Hammer, saw, and pliers!! Naaa, I went into the junk pile and am trying to find a fan that will act as a cooling fan behind grill.

Re: Great Dane excavating co.
 

You know that computer repair job would go a lot quicker if you used a gas wrench!

Re: Great Dane excavating co.
 

No not a gas wrench just needs a bigger hammer I find that I can fix anything with my 4 pound hammer. Ed

Re: Great Dane excavating co.
 

Excellent tool choice ! You could add TNT for a more speedy result ;o)

Re: Great Dane excavating co.
 

Hi Cooper

For It repairs I always fine the Hammer a good option and as Jammer said 4 pound is good if all else fails threaten it with the industrial shredder I have done that a few times at work and it usualy prompt the misbehaving IT kit to buck its ideas up.
We use the shredder for end of life kit and for security reasons it turns it all into metal confetie which is then recycled amazing piece of kit.
However know where near as much for as RC please keep posting this excellent build

thanks

Re: Great Dane excavating co.
 

Found the perfect fan, it was the one inside the power source from the computer. And I got done messing with different esc. The original one I was using was Novak crusher, good for rock crawlers. It was getting pretty hot, don't think it would hold up to much abuse and I don't know what Amp rating is but it can't be much.

http://i1357.photobucket.com/albums/...psoz6ivbos.jpg

Just so happens I had this one laying around , and it works with novac sensored motors. Just tested it on bench and all good, next is to stuff it in the belly of the beast. I figured if I'm showing the build might as well go through the growing pains of working on the electronics as well. I may lengthen the on/off switch and just use that for a kill button. Going to be adding other remote switches for lights etc,,

A video showing the cylinder working, no drips, working flawlessly:). I have another video but for so reason it keeps failing to upload?? Once it does I'll post that one also.

Re: Great Dane excavating co.
 

Because you live in east bumble f**** nowhere

Re: Great Dane excavating co.
 

Wow...excellent job on those cylinders!! In fact excellent job on the whole build!! The amount of time and work you put into this truck is finally paying off, seeing it finished and painted must be a great feeling of accomplishment, definitely a build to be proud of !!!
KP

Re: Great Dane excavating co.
 

I salute you RW..Knocked this out of the park ...At this point I would never tackle the cylinders you made ..very cool...nice work

Re: Great Dane excavating co.

And another quick video keeping with the Great Dane construction company business model of never harming animals:). Just displacing them!!

Re: Great Dane excavating co.
 

LOL that poor cat puts up with a lot of **** from you

Re: Great Dane excavating co.
 

Cooper those cylinders look great. They work nice ans smooth going up and down. Ed

Re: Great Dane excavating co.
 

Nice video RW, the wife and daughter both liked it, I figured it was about the cats but both made comments about the truck, been around me too long I guess. They said don't dump the cat before you ever got to that point lol. I really like the speeds both hydraulic and drive speed!

Re: Great Dane excavating co.
 

Hey cooper what kind of batteries and what size are they that you run in your truck and d11?

Re: Great Dane excavating co.
 

3s 8400 mah turnigy (hobbyking) but they discontinued them!! They were replacements for traxxss stadium trucks. Only need high quality batteries when you are near limits of amp discharge capibilities of battery. I.e. I use dinogy batteries in my boat, 10s (two 5s wired inseries) 5000mah per side, twin motors. This boat pulls 400 amps per side but deplets batteries in less than 3 min run times. But any more time and things melt:(. I pay good $ from r those batteries because I need to, on all the trucks and stuff I'm not anywhere near stressing even the cheapest of batteries. Just depends on quality. There are only about 6 battery manufacturers but a lot of companies rebrand and sell as theirs. Use to know what factories were selling whose batteries but it is really hard to figure me that info anymore, companies don't want to share trade secrets.
