Piston Wrist Pin Removal

Post by tkekfs » Mon Apr 04, 2005 9:33 pm

Does anyone have any neat tricks for removing the wrist pins that hold the pistons on? I have removed the cir-clips and the pins move but seem to be interference fit. I heard once that you are supposed to heat up the piston so it expands and then slide the pins out, but this was on a big car engine. Does this apply or is there a better way?<br /><br />Thanks in advance.

the piston pins are a floating type and after removing the circlips should slide out.. hope that helps..

Make a puller from threaded rod and different size washers. Put a BIG washer over the piston on the 'tightening side', install a nut and tighten away. The piston pins are not a real interference fit.
