I have an 88 LMC 1200.

Engine is a 300 CID straight 6 Ford industrial. Pretty reliable motor. Mine did crack a cam gear though.

Transmission is a Ford C6. Rear diff should be the OC12.

Provided it's been cared for there should be no major issues other than normal wear and tear on a 30 plus year old machine.

We all hope you document it with PHOTOS so we can see:

@PJL it's in pretty rough shape, it had some electrical issues and needs a harness. but I did want a project.

@Melensdad I hope to document the resurrection as it goes along, and I'm sure that I'll be bothering all of you with plenty of questions along the way

So does anyone here have a wiring diagram for one of these? Im a bit confused on this machine, I read somewhere in here that they stopped using aluminum cabs on these in '81. This one has an aluminum top and steel tub what gives? Any ideas?

1 more thing, is it possible to disconnect the hydros on this? I don't trust the hoses at all, will pulling the belt on the pump hurt the rear diff?

The 88 has a steel tub and aluminum cab. The doors are steel.

The hydraulic pump helps to cool the diff oil. Mine has the pump and cooler only. No hydraulics.

Thanks for the info PJL. I think I'll keep the pump and cooler and ditch the rest for now. Would you happen to know how the vin #'s break down on these?

Your cat was built third to the last of 1983. That was run #338
The last 1983 1200C was serial number 1953
