I've got a great tool for that and I just left E-Bay looking for one to show but with no luck. It's made by Lisle, it's black and cone-shaped with threads that taps and screws itself into the old bushing. Then you put a grease gun on it's zerk fitting, pump a few times, and presto......the hydraulic pressure will just pop that thing right out! I had my doubts about it when I first bought the tool, but it has worked flawlessly every time now for me.

Poor mans way is to thread a course thread bolt right into the center. Once the bolt bottoms out the pilot bushing walks right out. Works slick. The bushing is soft & the bolt is hard

put a bunch of wax threw the bushing and find a shaft that snugly fits into the hole. hit the shaft with a hammer and keep adding wax. The bushing will come out. Some guys use grease but that just gets messy.

Done, that was easier than I thought it would be. Grease and a dowel did the job. Whats be for a new bushing, roller or solid bushing. Thanks again http://www.yenko.net/ubbthreads/images/graemlins/youguysrock.gif

I never really like those roller bearings. I like a regular bronze bushing or maybe even one of those new Kevlar Composite bushings. Also, after you drive the new bushing in place, check the inner diameter 'cuz it like to shrink a bit and make the tranny input shaft hard to insert.

I run a 5/8" NC tap through the bushing, then run a 5/8" bolt in it and the bushing comes right out - no grease, no mess.

When you get a replacement, take a magnet with you and make sure the new bushing isn't attracted to the magnet; there are lots of cheap Chinese bushings out there that have lots of iron in them instead of being 100% Oilite bronze. The case-hardening on the input shaft doesn't get along with any iron in the bushing.
