Note:
Disassembly of the piston, press fit design piston pin, andconnecting rod may create scoring or damage to the piston pin andpiston pin bore. If the piston, pin, and connecting rod have beendisassembled, replace the components as an assembly.Many internal engine components will develop specific wearpatterns on their friction surfaces.When disassembling the engine, internal components MUST beseparated, marked, or organized in a way to ensure installation totheir original location and position.Separate, mark, or organize the following components:
Piston and the piston pinPiston to the specific cylinder borePiston rings to the pistonConnecting rod to the crankshaft journalConnecting rod to the bearing capA paint stick or etching/engraving type tool are recommended.Stamping the connecting rod or cap near the bearing bore may affectcomponent geometry.
