Description
| Selection points | Selection parts | Selection items | Selection methods |
|---|---|---|---|
| Between cylinder block and 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 and connecting rod | Connecting rod bearing | Connecting rod bearing grade (bearing thickness) | Combining service grades for connecting rod big end diameter and crankshaft pin outer diameter determine connecting rod bearing selection. |
| Between cylinder block and piston | Piston and piston pin assembly (piston is available together with piston pin as an assembly.) | Piston grade (piston outer diameter) | Piston grade = cylinder bore grade (inner diameter of bore) |
- 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, refer to the text.
Scheme 6
- Check the cylinder bore grade on rear left side of cylinder block (L), and select piston of the same grade.
- If there is a correction stamp mark on the cylinder block, use it as a correct reference.
Scheme 7
- Measure the cylinder bore inner diameter. Refer to " «CYLINDER BLOCK»(ref-516394-S33770760562012120600000) ".
- Determine the bore grade by comparing the measurement with the values under the cylinder bore inner diameter of the "Piston Selection Table".
- Select piston of the same grade.
