Not sure if this is well known or not, but I just delighted myself with it. I was trying to yank my crank pilot bearing, and succeeded in pulling out the bearing but not the surrounding bushing. I couldn't get my puller to grab the bushing, so after a bit of thought I:
* chose a socket that was a tight fit to the bushing inner diameter
* put a bolt + washer through the socket, another washer + bolt on the end and tightened
* filled the bushing recess with grease
* inserted the socket (piston) into the bushing
* applied a BFH - three whacks
The hydraulic pressure of the grease pushed out the bushing painlessly - an amazingly gratifying experience. This avoided a next-day trip to buy a new puller, or hours of Rube-Goldberg kibitzing.
So satisfying, I might just hammer in the old bushing so I can take it out again!
