Separating Parts

Separating Parts

Important:

* 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.

* When disassembling the engine, internal components MUST be separated, marked, or organized in a way to ensure installation to their original location and position.

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
* Connecting rod to the bearing cap
A paint stick or etching/engraving type tool are recommended. Stamping the connecting rod or cap near the bearing bore may affect component geometry.
* Crankshaft main and connecting rod bearings
* Camshaft and valve lifters
* Valve lifters, lifter guides, pushrods and rocker arm assemblies
* Valve to the valve guide
* Valve spring and shim to the cylinder head location
* Engine block main bearing cap location and direction
* Oil pump drive and driven gears
