Check Piston Connection
- Before removing the piston, test the condition of the connecting rod opening, needle bearing, and wrist pin.
- Grip the connecting rod with one hand, and try to rock, not slide, the piston side to side.
- If there is any play in the piston connection, you already know something is out of spec.
- Remove the pin clips with a pick and safety glasses, because they might go flying.
- Assemble your wrist pin removal tool, and press the pin from of the cylinder.
- Remove the needle bearing, and wrap your connecting rod with a clean shop towel.
