JDcrawlers Messageboard

As of yesterday, 12/23, I am again the owner of a functional JD 350C crawler loader. Thanks to everyone here who provided advice, and encouragement. With the new undercarriage she works like a dream, a far cry from where she was before the project.

Thanks for all the advice so far. She's half apart right now. Discovered that old wear strips were so badly worn that there is not inconsequential wear to the frame itself. Should I build up the frame and bring it back to the original dimensions? If so do we know what flavor of steel the frame is ma...

The part I am most concerned about is removing / inserting the pin, the tech manual tells you to use a D-01030AA which I assume even if I could find i assume would be super expensive (other generic track pin pushers I could find prices on look like 2- 3k+). removal is probably going to be an oxy tor...

Thanks for the advice, the ball check valve was packed solid, cleaned it out and it fired right up!

I am just a bit curious....have you checked on the fuel injector pump for failure of the pentane gasket ( pellets) that have been discussed on this forum ??? this is usually a problem with the roosa master pump. interferes with fuel to cylinders and dies from build up of pellets I was not checking ...

I have a 350CB (crawler loader) serial number 329326T (which according to a post on this forum puts it as a 1979 model) with engine model 3164DF 01 serial number 461445T which is having some issues. I will recount the events as they happened in order, not as I learned them, so some of my diagnostic ...
