CYLINDER BLOCK

CAUTION:

Do not rotate crankshaft.

• Remove main bearing cap and bearings, and using the scale (A)

on the plastigage bag, measure the plastigage width. 

NOTE:

The procedure when the measured value exceeds the limit is

same as that described in the “Method by Calculation”.

MAIN BEARING CRUSH HEIGHT 

• When main bearing cap is removed after being tightened to the

specified torque with main bearings (1) installed, the tip end of

bearing must protrude (B). Refer to 

EM-93, "Disassembly and

Assembly"

.

• If the standard is not met, replace main bearings.

CONNECTING ROD BEARING CRUSH HEIGHT

• When connecting rod cap is removed after being tightened to the

specified torque with connecting rod bearings (1) installed, the tip

end of bearing must protrude (B). Refer to 

EM-93, "Disassembly

and Assembly"

.

• If the standard is not met, replace connecting rod bearings.

MAIN BEARING CAP BOLT OUTER DIAMETER 

• Measure the outer diameters (d

1

) and (d

2

) at two positions as

shown.

• If reduction appears in places other than (B) range, regard it as

(d

2

).

• If it exceeds the limit (a large difference in dimensions), replace

main bearing cap bolt with a new one.

• Measure the outer diameter (d) at position as shown.

• If reduction appears in a position other than (d), regard it as (d).

• When (d) is less than the limit (when it becomes thinner), replace

connecting rod cap bolt with a new one.

FLYWHEEL DEFLECTION (M/T models)

• Measure the deflection of flywheel contact surface to torque with a

suitable tool (A).

• Measure the deflection at 210 mm (8.27 in) diameter.

• If measured value is out of the standard, replace flywheel.

• If a trace of burn or discoloration is found on the surface, clean it

with sandpaper.

CAUTION:

When measuring, keep magnetic fields (such as dial indicator

stand) away from signal plate of the rear end of crankshaft.

Limit: 7.75 mm (0.3051 in)

HOW TO SELECT PISTON AND BEARING

Description

INFOID:0000000009444756

• 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 for the appropriate part.

Connecting Rod Bearing

INFOID:0000000009444757

WHEN NEW CONNECTING ROD AND CRANKSHAFT ARE USED

1. Apply connecting rod big end diameter grade stamped (C) on

connecting 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-101, "Inspection"

.

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.
