Removing the Piston

The piston has a coating of molybdenum and graphite on the skirt, which lubricates contact with the cylinder. If the piston skirt is in good condition, you can reuse the piston.

Note the orientation of the piston. The arrow on the piston must face the exhaust header.

Stuff a rag into the hole surrounding the piston to prevent dropping a wristpin circlip into the engine. Remove one of the wristpin circlips. From the opposite side of the piston, push the piston pin out of the piston, and remove the piston from the connecting rod of the crankshaft.

Remove the piston rings from the piston.
