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

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.

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:).

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.

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.
 

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:).

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.
