With the tranny removed, Bob and I turned our attention to the clutch. Six bolts attach the clutch to the flywheel. We grabbed a half inch impact wrench and quickly made short work of it. Watch that last bolt when you take it out to keep the flywheel from crunching your toes.
The clutch was set aside and that left the flywheel. It is held in place with a half dozen bolts. The impact wrench was used to remove the bolts. Again, be careful when the last bolt is coming out.
I was quite pleased to see the condition of the clutch and flywheel. There was no discoloration from "smoking the clutch" and no grooves or other marks. There was a reasonable amount of clutch material still remaining before the rivets got into the flywheel. It had approximately 72,500 miles on it. 4.56 gears and a 4:1 transfer case sure makes for a longer clutch life. I've been on the trail and smelled the hot clutch from other Jeeps. Too bad for them.
The business end of the crankshaft was next on the list of "things to do" before the AW-4 could be installed. The pilot bushing and the spacer around it had to be removed. Neither were needed by the torque converter which was going to be parked in the end of the crankshaft.
While NOT at all necessary to "save" the pilot bearing, I decided to give this nifty bearing puller a try. Troy had it in one of his tool box drawers and so I decided to give it a shot. I had to put the flywheel back on so that the puller could function as intended (there was a ridge without the flywheel installed that caused the puller to sit off-camber).
And there you have it. The perfectly good pilot bearing very cleanly extracted by the puller....still in good shape (although it will end up in the trash as I've no need for it). It is always nice to have the right tool for the job as it honestly does make it easier.
