• Remove main bearing cap and bearings, and using the scale on

the plastigage bag, measure the plastigage width. 
NOTE:
The procedure when the measured value exceeds the standard is
the same as that described in “Method by Calculation”.

FLYWHEEL INSPECTION

For a dual mass flywheel which has worked: presence of a free rotation angle. This angle is measured by fix-
ing the primary flywheel and turning the secondary flywheel. The dual mass flywheel free rotation angle must
not exceed 15

°

 or 30mm (1.2 in) in linear movement measured on the edge.

HOW TO SELECT PISTON AND BEARING

Description

INFOID:0000000010282027

• 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.

Main Bearing

INFOID:0000000010282028

WHEN NEW CYLINDER BLOCK AND CRANKSHAFT ARE USED

1.

“Main Bearing Selection Table” rows correspond to main bearing
housing grade on rear side of cylinder block.
• * This engine only has one cylinder bore grade.

(1) : cylinder block bearing diameter category:

• Identification by letter of the crankshaft bearing diameter,
• the order of the marking letters goes from the bearing on the

timing end to the bearing on  the flywheel end.

• (2) : cylinder diameter category.
• (3) : marking only for factory use.

WORKING OUT THE CLASS OF MAIN BEARING (ORIGINAL FITMENT)

Marking (1) On The Crankshaft

Identify the category of crankshaft main journal diameter (A) with
checking the marking of crankshaft as shown in the figures.
NOTE:
The marking has 5 digits. Left end is the diameter category of No. 1
bearing (flywheel side) and right end is the diameter category of No.
5 bearing (sprocket side).

Detail of the marking (1):
(1) : Line indicating the diameter category of the journal.
- identification by letters corresponding to the diameter of the journal
- the order of the marking letters goes from the bearing on the timing end to the bearing on the flywheel end,
(2) :Line indicating the diameter class of the crankpins,
(3), (4) : Last five numbers of the crankshaft part number,
(5): Line reserved for the factory. 

Table Of Journal Diameter Classes

Unit: mm (in)

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-459, "Inspection"

.

2.

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

3.

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

4.

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