HOW TO SELECT PISTON AND BEARING

Description

INFOID:0000000010282253

• 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.

HOW TO SELECT PISTON AND BEARING

1.

“Main Bearing Selection Table” rows correspond to main bearing
housing grade on left side of cylinder block.

• If there is a corrected stamp mark (B) on cylinder block, use it

as a correct reference.

2.

Apply main journal diameter grade stamped on crankshaft front
side to column in the “Main Bearing Selection Table”.

3.

Read the symbol at the cross point of selected row and column in the “Main Bearing Selection Table”.

4.

Apply the symbol obtained to the “Main Bearing Grade Table” to select main bearing.
NOTE:
Service part is available as a set of both upper and lower.

When Cylinder Block and Crankshaft Are Reused

1.

Measure the dimensions of the cylinder block main bearing housing inner diameter and crankshaft main
journal diameter individually. Refer to 

EM-102, "Inspection"

.

2.

Apply the measured dimension to the “Main Bearing Selection Table”.

3.

Read the symbol at the cross point of selected row and column in the “Main Bearing Selection Table”.

4.

Apply the symbol obtained to the “Main Bearing Grade Table” to select main bearing.
