DESCRIPTION
| Connecting points | Connecting 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 (Housing inside diameter) and crankshaft journal grade (journal outside diameter) |
| Between crankshaft to connecting rod | Connecting rod bearing | Connecting rod bearing grade (bearing thickness) | Connecting rod bearing grade = crankshaft pin grade (pin diameter). No grade exists for inside diameter of connecting rod large end. |
| Between cylinder block to piston | Piston and piston pin assembly. The piston is available together with piston pin as an assembly. | Piston grade (piston diameter) | Piston grade = cylinder bore grade (diameter of bore) |

CONNECTING PARTS DESCRIPTION
(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, refer to the text.
