I know nothing other than I have put highway equipment power plants on loaders ( usually Volvo ) and I have put loader / industrial equipment on the road. one m37 one 48 power wagon.

……. removal of the old ''manual'' transmission mounts on the frame. due to the tight area of the ''intermediate'' driveshaft.... the pressed in studs on the transmission output drive flange are too long , to permit easy/quick removal of shaft. the input ''slip-yolk'' of the transfercase, only has a few inches of clearance , for this procedure...… the mounting bolts for the p/b anchor plate will need to be replaced , with the ''thin'' headed type bolts... so will adapt over to bolts , instead of studs...

I recently had to change the clutch and throw out bearing on a 318 in a 542CF. To disconnect the upper driveline, I drop both front and back drive lines, remove the transfer case mounting bolt except the lower back two and tilt the case back. Not so difficult. Maybe an option if your fix makes putting a wrench on both ends of the bolts a problem.

Good idea... I 'll fab it so I 'll only need one wrench. Up on the mountain....we would pull the engine to do a clutch...and leave the tranny in place.... Thx ?

Try that on a 542 CF. The engine has to come out through the passenger door if you are lucky.

They must have got the idea from Tucker. Build the cab around the drive train.

I had a fire engine that was built that way. The body builder welded the subframe around the chassis members trapping the pump. We wound up cutting the back out of the cab to perform what should have been a simple 1 hour repair.


I learned a thing or two about contract specifications ... a a few new words.
