Separating Parts

Important: 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 reinstallation 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, guides, pushrods, pivot supports and rocker arms
* 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
