Oil Clearance between Idle Gear Shaft and Idle Gear Bushing

1. Measure the idle gear shaft O.D. with an external micrometer.
2. Measure the idle gear bushing I.D. with an internal micrometer.
3. Calculate the oil clearance.
4. If the oil clearance is more than the allowable limit, replace the

bushing.

5. If the oil clearance stays more than the allowable limit, replace

the idle gear shaft also.

Replacement of Idle Gear Bushing
(When removing)

1. Press out the used idle gear bushing with the replacing tool.

(See page

"SPECIAL TOOLS"

.)

(When installing)

1. Clean a new idle gear bushing and idle gear bore, and apply

engine oil to them.

2. Press fit the new bushing with the replacing tool.

Make sure that the bushing end aligns the end of the idle gear.

Side Clearance of Balancer Shaft (for Balancer Model Only)

1. Set a dial indicator with its point on the balancer shaft.
2. Move the balancer shaft to the front and rear to measure the

side clearance.

3. If the measurement is more than the allowable limit, replace the

balancer shaft.

M00000003ENS0127US1

Balancer Shaft Bend (for Balancer Model Only)

1. Hold the balancer shaft with V blocks on the surface plate.
2. Set a dial indicator with its point on the middle journal at a high

angle.

3. Turn the balancer shaft slowly and read the variation on the

indicator.

4. If the measurement is more than the allowable limit, replace the

balancer shaft.
