I have a tip on how to remove a pilot bushing...Years ago, I was working as a truck fleet mechanic and had a clutch job underway. The pilot bushing was stubborn and would not come out of the crankshaft. An older, retired mechanic shared a solution that has served me well since: 1) Pack the crankshaft cavity and pilot bore with grease. 2) Use an old input gear or a steel rod of the same diameter as the pilot bearing I.D.; put on your safety goggles and drive the input gear (nose end) or steel rod into the pilot bore. You can use a sand filled large plastic hammer on the back end of the input gear or a short handled steel sledge on the steel rod's end. 3) The impact force and close fit turns the grease into a hydraulic ram. Grease drives the bushing out from its backside. This works especially well if the bushing has a larger O.D. If the bushing is thin-walled, the task is more difficult. On a caged needle bearing pilot, this may not work (grease slips past the needles and pressure drops), but it's worth a try. Moses
