You have to take the four bolts out of the side of the transfer case and remove the shifter shaft. look in manual -34-1, page 7-45 and that is where the procedure starts. To much to try to describe on here.

I removed the 4 bolt inspection plate but with only 3/4' space between tran. hsg. & cross member vertical pylon it would take special made snap ring pliers for me to even attempt to accomplish task! So in about 2 hours of additional work the engine/tran. assy. is ready to pull. Of course that opens up a big can of worms deciding what else to do with engine bay & oil pan leaks etc. etc.

Yep, and once the pan is off to fix the gasket you know you will need to take a look at the rod and main bearings and you might as well replace that rear main seal, But wait, you are halfway there plus it is hanging right in front of you so you might as well pull the front timing gear cover and replace the front crank seal and cover gasket. Well, we had to take the water pump off to do that....................................., Yea, I know exactly how that goes. :roll: :lol:

I have done it using a screw, then when that did not work, I used needle nose pliers that I ground "thinner", tiny locking pliers and various modified screwdrivers bent into a hook.... three hours later I had a new one in. I was lucky and did not damage the shaft.

I would follow Rick's advice, its the correct procedure.

The snap rings on the shifter shaft were actually E clips so I made a 2 prong fork out of 1/16 " & pushed them off the shaft & yes I did stuff rags in there so I wouldn't have to go on a fishing trip! With power unit out of chassis I believe the only oil leak is the right rear corner of valve cover. Going to live life on the edge & not mess with the pan gskt. ( going to replace side cover gskt.) . The clutch has the ceramic button style disc; too grabby & really scours the surface of the pressure plate & flywheel . The guy who sold me MUTT sent a new pressure plate & disc with it; the number on the pressure plate on engine & spare both say: 8328265 , the spare disc which is what I call a composite ( not button ) has no numbers. The 34P shows two choices on pressure plate & disc ! GOAL: eliminate button style , QUESTION : will 8328265 pp & composite disc work together ?

TIA

Buzzin....

the 8328265 disk will work fine.....miles smoother than the button-type (which by the way is p/n 11669136). While you are swapping the clutch disk, why not check the condition of the release bearing? If it feels rough or rattles, get a new one.

Check the flywheel closely. When I took out my puck clutch the flywheel was really chewed up by it and needed to be turned before putting in the new disc. You can try putting the new disc right in but you are taking the chance that the chewed flywheel will eat the disc right up.
