Connecting Rod Bearing

INFOID:0000000012197314

WHEN NEW CONNECTING ROD AND CRANKSHAFT ARE USED

1. Apply connecting rod big end diameter grade stamped on con-

necting rod side face to the row in the “Connecting Rod Bearing

Selection Table”.

2. Apply crankshaft pin journal diameter grade stamped on crank-

shaft front side to the column in the “Connecting Rod Bearing

Selection Table”.

3. Read the symbol at the cross point of selected row and column in the “Connecting Rod Bearing Selection

Table”.

4. Apply the symbol obtained to the “Connecting Rod Bearing Grade Table” to select connecting rod bearing.

WHEN CONNECTING ROD AND CRANKSHAFT ARE REUSED

1. Measure the dimensions of the connecting rod big end diameter and crankshaft pin journal diameter indi-

vidually. Refer to 

EM-123, "Inspection"

2. Apply the measured dimension to the “Connecting Rod Bearing Selection Table”.
3. Read the symbol at the cross point of selected row and column in the “Connecting Rod Bearing Selection

Table”.

4. Apply the symbol obtained to the “Connecting Rod Bearing Grade Table” to select connecting rod bearing.

UNDERSIZE BEARINGS USAGE GUIDE

• When the specified connecting rod bearing oil clearance is not obtained with standard size connecting rod

bearings, use undersize (US) bearings.

• When using undersize (US) bearing, measure the connecting rod bearing inner diameter with bearing

installed, and grind the crankshaft pin so that the connecting rod bearing oil clearance satisfies the standard. 

CAUTION:

HOW TO SELECT PISTON AND BEARING

In grinding crankshaft pin to use undersize bearings, keep the

fillet R [1.5 - 1.7 mm (0.059 - 0.067 in)] (A).

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-123, "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”.

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.
