SwedishD, now that is an impressive little tool there. I suppose it works better for the solid bushing type pilot rather than the needle bearing type as the threads may not engage in the needle bearing type pilot. Very interesting little tool........grease hydraulics without the dowel and hammer.

I just got through trying the Lisle grease pressure tool. It won't work for the steel roller pilot bearing on the Jeep which I suspected. It does state on the package, not to use on steel. I'll keep it back for brass or bronze bushings. I did use the above method using a bolt behind the pilot bearing and it worked great.
Hopefully this afternoon, I'll have the engine back in the Jeep. It's
suppose to snow on Thursday. Too bad it won't be ready by then.

that grease method is a whole lot of grease. I tried that today, and there is a big void behind the flywheel and the crank.
I cheated...i pulled the flywheel & drove the old sucker out

jpfix...I'm confused. The pilot bearing is inside the end of the crank, not inside the flywheel proper. Tell me more. Glad whatever you did worked for you though.

Edit--on the 4 cyl, the pilot bearing/bushing is installed in the flywheel, whereas in the 6 cyl, it is installed into the back end of the crank

I always thought that too...but this crank on the 2.5L is smmoooooth on the inside, about the size of half a golfball. there is a rollerbearing in the flywheel, carries the shaft going into the transmission. maybe it is a thing with the early 90s 4cyl. the pilot bearing that comes in the clutch kit fits nicely in the center of the flywheel...three easy raps drive it into place.

Interesting. I haven't seen this before. Of course that doesn't mean it isn't normal for many different vehicles, and certainly I am not universally experienced in pilot bearings in all vehicles. Interesting nonetheless.

Tried this last night and it worked very easy. I just used a socket bigger than the pilot bushing though. No mess, no grease and out in very little time. Thanks for the idea.





That is why I like Jeep Forum...you can find little ideas to make the job easier. And I ended up with this.

Thank you for posting that - you are a genius. I was really stuck and executed (roughly) on your idea and out it came. You saved my XXX.

You guys brought this thread back a little late for me I ended up with a tool I rented from Advanced auto but like yours better.
The 'socket' method is just like a stuck case remover for reloading metal ammo, I made my own but didn't think to use it for my pilot bearing.
