14. Dismantle the crankcase.

FE02-0261b

15. Dismantle the No.3 bearing

crankshaft thrust film.

Note: Rotate the crankshaft during
removing, so that the thrust film can
exit together to facilitate the removal.

Crankshaft inspection, the crankshaft bearing clearance matching inspection procedure:

1. Measure the main bearing bore diameter with an inner diameter micrometer and record.

2. Measure diameter dimension of main shaft of crankshaft by using outside micrometer and

record result.

3. Select the crankshaft main bearing dimensions according to the recorded dimensions in the

1043

following table .

Inner diameter of main
bearing seat (mm/in)

External diameter of
crankshaft main journal
(mm/in)

Select the thickness of the
main bearing (mm/in)

4. Install the crankshaft bearing

crankshaft and inspect whether
the middle of the crankshaft
journal has acceptable loss of
roundness and the beating
degree.

Standard Value

Roundness 0.003 mm (Metric)/0.0001
in (English system)

Run Out 0.02 mm (Metric) /0.0008 in
(English system)

5. Inspect the crankshaft axial

clearance.

Standard Value

0.04 ～ 0.24 mm(Metric)/0.0015 ～
0.0094 in（English system）

6. With a plastic gap measurement

regulator, measure all the
crankshaft bearings.

Important precaution: apply
lubricating grease on the crankshaft
journal and slightly lubricate the
crankshaft bearing, so that the plastic
clearance gauge is not torn when
disassembling the crankshaft bearing
cap.

7. According to the width of

bearing 1, cut the plastic gap
measurement regulator, place the
plastic along the axis between the
journal and the crankshaft
bearings.

9. Dismantle

the

crankcase.

10. Use scales on feeler gauge to

measure thickness 1 of extended
plastic strip. Inspect whether
crankshaft bearing clearance
value is in the following range:

Standard value :0 . 015-0 .
033mm/0 . 0006-0 . 0013in

11. If the gap value is not within the

specified range, re-adjust the
crankshaft clearance. If
necessary, replace the crankshaft.

Installation Procedures:

1.

Clean all the relevant
components.

2. Apply a small amount of engine

lubrication oil to the crankshaft
bearing.

3. Install the selected crankshaft

bearings.

5. Install the crankshaft thrust half

ring with the grooved side facing
outside.

6. Inspect the crankshaft axial

clearance, to confirm the
crankshaft axial clearance is
acceptable. Refer to 2.13.1.2
Mechanical System
Specification.
