Separating Parts
Note:
| • | Disassembly of the piston, press fit design gudgeon pin, and connecting rod may create scoring or damage to the gudgeon pin and gudgeon 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 gudgeon 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 big end bearings |
| • | Camshaft and valve tappets |
| • | 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 |
