HOW TO SELECT PISTON AND BEARING
1. “Main Bearing Selection Table” rows correspond to main bearing
housing grade on rear left side of cylinder block (L).
 If there is a correction stamp mark 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”.
CAUTION:
There are two main bearing selection tables. One is for No. 1, 4 and 5 journals and the other is for
No. 2 and 3 journals. Make certain to use the appropriate table. This is due to differences in the
specified clearances.
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-219, "
Inspection After Disassembly" and EM-219, "Inspection
After Disassembly".
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”.
CAUTION:
There are two main bearing selection tables. One is for No. 1, 4 and 5 journals and the other is for
No. 2 and 3 journals. Make certain to use the appropriate table. This is due to differences in the
specified clearances.

P O Use Undersize Bearing Usage Guide
 When the specified main bearing oil clearance is not obtained with standard size main bearings, use under-
size (US) bearing.
 When using undersize (US) bearing, measure the main bearing inner diameter with bearing installed, and
grind main journal so that the main bearing oil clearance satisfies the standard.
CAUTION:
In grinding crankshaft main journal to use undersize bearings,
keep the fillet R [1.5 - 1.7 mm (0.059 - 0.067 in)] (A).
