Note:
- Disassembly of the piston, press fit design piston pin, and connecting
rod may create scoring or damage to the piston pin and piston pin bore.
If the piston, pin, and connecting rod have been disassembled, replace the
components as an assembly.
- Many internal engine components will develop specific wear patterns
on their friction surfaces.

Separate, mark, or organize the following components:
- Piston and the piston pin
- Piston to the specific cylinder bore
- Piston rings to the piston
- Connecting rod to the crankshaft journal
