Unimog Clutch Work Don't try this at home kids!

Unimogs are not NORMAL vehicles ! Normally to work on the clutch of a vehicle it is a simple matter to drop the drive shaft, unbolt the tranny and pull it out. Replace the bad parts inside and reverse the procedure.

NOT IN A UNIMOG!

The Unimog has a drive shaft that is not easily droppable! And the clutch parts come out by removing the engine instead! WOW! What a pain!

Someone told me the Cab has to be removed to pull the engine! AARRGH! But, according to the Unimog service manual and the Unimog Guru Craig Tull, the motor can be scooted forward enough to change the clutch parts!

First chore is to remove the mogs hood and front glass and all the floor panels of the cab. Then drain the coolant (there is alot of it!) and pull the Air compressor (if you have one) the Radiator (first take off the bottom skid plate and the heat exchanger!) and the fan....

with radiator and other goodies removed there is alot of space to work with! I also removed the air cleaner. And a whole tangle of heater hoses! (they go everywhere!)

Next remove the valve cover and ya gotta remove the oil filter from the left rear of the engine.

We used two hand pulleys, one attached to a bolt on the front of the block and one attached to the rear of the block. We hooked the top of the pulleys to the strong rafters in our shop since we didn't have an engine hoist. We pulled up the engine a bit until it was free and then pushed the MOG backwards so the hanging engine would pop free of the bell housing...

Got the new parts on the engine and aligned and now just to slip it all back together. Easy as pie!

Our homemade alignment tool! I filed on a craftsman screwdriver with the bench grinder to make a clutch alignment tool, My Mac Tool man wanted to sell me an alignment tool but we were not sure which one worked, when he comes by next week I will certainly tell him I got it from Sears! ha ha. (Sears doesn't have clutch alignment tools)...
