DESCRIPTION
| Selection points | Selection parts | Selection items | Selection methods |
|---|---|---|---|
| Between cylinder block to crankshaft | Main bearing | Main bearing grade (bearing thickness) | Determined by match of cylinder block bearing housing grade (inner diameter of housing) and crankshaft journal grade (outer diameter of journal) |
| Between crankshaft to connecting rod | Connecting rod bearing | Connecting rod bearing grade (bearing thickness) | Combining service grades for connecting rod big end inner diameter and crankshaft pin outer diameter determine connecting rod bearing selection |
| Between cylinder block to piston | Piston and piston pin assembly (The piston is available together with piston pin as an assembly) | Piston grade (piston outer diameter) | Piston grade = cylinder bore grade (inner diameter of bore) |
| (1) Between piston to connecting rod | |||
| (1) For the service parts, the grade for fitting cannot be selected between a piston pin and a connecting rod. (Only 0 grade is available.) The information at the shipment from the plant is described as a reference. | |||

- The identification grade stamped on each part is the grade for the dimension measured in new condition. This grade cannot apply to reused parts.
- For reused or repaired parts, measure the dimension accurately. Determine the grade by comparing the measurement with the values of each selection table.
- For details of the measurement method of each part, the reuse standards, and the selection method of the selective fitting parts, follow the applicable procedures.

- Check the cylinder bore grade on rear left side of cylinder block, and select a piston of the same grade.
- If there is a corrected stamp mark on the cylinder block, use it as a correct reference.
