6. Piston and Connecting Rod Assembly
1) Remove carbon deposits from the upper portion of the
cylinder wall with a scraper before removing the piston
and connecting rod.
2) Move the piston to the top of the cylinder and tap it
with a hammer grip or similar object from the
connecting rod lower side to drive it out.
3) If the connecting rod upper bearings are to be
reinstalled, mark their fitting positions by tagging each
bearing with the cylinder number from which it was
removed.
4) Clamp the connecting rod in a vise.
Take care not to damage the connecting rod.
Use a piston ring replacer to remove the piston rings.
Piston Ring Replacer
Do not attempt to use some other tool to remove the
piston rings. Piston ring stretching will result in
reduced piston ring tension.
5) Use a pair of pliers to remove the piston pin snap
rings.
