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.
