How To Select Piston And Bearing: Description
WARNING: This page is about a different car, the 2011 Nissan Murano. However, it is still accessible from the selected car via links, so may be relevant.
PISTON AND BEARING REFERENCE CHART
| 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 assembly.) | Piston grade (piston skirt diameter) | Piston grade = cylinder bore grade (inner diameter of bore) | ||
| Between piston and connecting rod(1) | - | - | - | ||

- 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.
