HOW TO SELECT MAIN BEARING
When New Cylinder Block and Crankshaft are Used
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-98, "
MAIN BEARING HOUSING INNER DIAMETER" and EM-
100, "CRANKSHAFT MAIN JOURNAL DIAMETER" .
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”.

When replacing piston and piston pin assembly, refer to EM-99, "Piston to Cylinder Bore Clearance" .
NOTE:

Piston is available together with piston pin as assembly.

Piston pin (piston pin hole) grade is provided only for the parts installed at the plant. For service parts,
no grades can be selected. (Only grade “0” is available.)
PISTON RING SIDE CLEARANCE

Measure the side clearance of piston ring and piston ring groove
with a feeler gauge (A).

If the measured value exceeds the limit, replace piston ring, and measure again. If it still exceeds the limit,
replace piston also.
PISTON RING END GAP

Make sure that cylinder bore inner diameter is within specification. Refer to EM-99, "Cylinder Bore Inner
Diameter" .

Lubricate with new engine oil to piston (1) and piston ring (2),
and then insert (A) piston ring until middle of cylinder (B) with
piston, and measure piston ring end gap with a feeler gauge (C).

If the measured value exceeds the limit, replace piston ring, and measure again. If it still exceeds the limit,
re-bore cylinder and use oversized piston and piston rings.Standard:
Top ring : 0.04 - 0.08 mm (0.002 - 0.003 in)
2nd ring : 0.03 - 0.07 mm (0.001 - 0.003 in)
