Thank you.....I'll take a look

I have my 1949 Crawler hydraulic system almost complete. It is equipped with many parts purchased from Lavoy as well as some fabricated by a couple different local machine shops. Before I put all the rest of it including body parts back on, I want to test the hydraulics for leaks. I have the origina...

Thanks Lavoy. I got the AW46 since it is 20W and the AW32 is 10W.

I finally have my 1949 MC with the mc1000 series hydraulic system and blade built. Thank you Lavoy for supplying most of the parts. I used two different machine shops to rebuild cylinders and make a few custom parts. I know it holds 11 quarts of oil but am not sure what is best for this system. It i...

Oh, that would be wonderful. I'm pretty excited about putting this old boy back together.

Lavoy did find a reservoir for me and many other parts. I am still missing the two spacers, one on each side, that mount the rear of the hydraulic cylinders with two more U bolts. I have the tracks removed but still need to raise the frame rails (2"x2") which are set at 90 deg from flat. Once I acqu...

Great info guys. I will contact Lavoy. In the interim, does the reservoir need to withstand the 600 psi the pump produces?

I actually found a book for the MC1000 system and it says the reservoir with the integral cylinders holds 11 quarts but I still don't know how much the reservoir itself holds.

I have my Model 1000 cylinders rebuilt and have most of the rest of the lift arms and blade either fixed or made in a machine shop. It occurs to me that before I make the hoses and connect the cam drive pump, etc., I need a reservoir. I do not have one nor do I know what they even look like, capacit...

I know this is a very old post but hoping someone will read it. I see mentioned a part schematic for the JD MC1000 Tool Carrier. I am rebuilding one that I acquired on two pallets and would love some documentation. Does anyone possess one of these schematics? If yes, I would love a copy and would ce...

Thanks for the help on this. I also don't have a crawler manual. I wonder where to get one????

I am trying to rebuild my set of (probably Holt) lift cylinders that mount inside the tracks. I have a 1949 MC. The hydraulic shop is stuck and I am looking for help with two questions about disassembling them. I have no documentation but I do have pictures of where we are in the disassembly process...

Lavoy, thank you!
do you sell these "O" rings?

I have put an image of my blade mounted on a 1951 that I saw at the Oregon SteamUp.

Can anyone identify it?
