Important

The piston and pin are a matched set. Arrange the pistons, pins, rings, connecting rods, and bearings in the correct order.

2. Remove the piston rings.




1. Using a piston ring expander, remove the compression rings.
2. Remove the oil ring by hand.




3. Disconnect the connecting rod from the piston.

Notice

Carefully remove any burrs in the piston bore, next to the snap ring groove, using an X-ACTO knife (or equivalent). This will prevent piston pin scoring during removal.
