INSPECTION

PROCEDURE

1. INSPECT REVERSE IDLER GEAR THRUST CLEARANCE

(a) Using a feeler gauge, measure the reverse idler gear thrust clearance.

Standard Clearance:

0.40 to 1.05 mm (0.0157 to 0.0413 in.)

Maximum Clearance:

1.05 mm (0.0413 in.)

If the clearance exceeds the maximum, replace the reverse idler gear, needle roller bearing or reverse idler gear shaft.

2. INSPECT REVERSE IDLER GEAR RADIAL CLEARANCE

(a) Using a dial indicator, measure the reverse idler gear radial clearance.

Standard Clearance:

0.015 to 0.048 mm (0.000591 to 0.00189 in.)

Maximum Clearance:

0.048 mm (0.00189 in.)

If the clearance exceeds the maximum, replace the reverse idler gear, needle roller bearing or reverse idler gear shaft.

3. INSPECT NO. 1 GEAR SHIFT FORK

(a) Using a micrometer, measure the outer diameter of the No. 1 gear shift fork.

Standard Outer Diameter:

13.982 to 14.00 mm (0.5505 to 0.5512 in.)

Minimum Outer Diameter:

13.982 mm (0.5505 in.)

If the outer diameter is less than the minimum, replace the No. 1 gear shift fork.

(b) Using a vernier caliper, measure the No. 1 gear shift fork.

Standard Thickness:

9.50 to 9.80 mm (0.374 to 0.386 in.)

If the thickness is not as specified, replace the No. 1 gear shift fork.

4. INSPECT 3RD AND 4TH SHIFT FORK SHAFT

(a) Using a micrometer, measure the outer diameter of the 3rd and 4th shift fork shaft.

Standard Outer Diameter:

13.982 to 14.00 mm (0.5505 to 0.5512 in.)

Minimum Outer Diameter:

13.982 mm (0.5505 in.)

If the outer diameter is less than the minimum, replace the 3rd and 4th shift fork shaft.

5. INSPECT NO. 3 GEAR SHIFT FORK

(a) Using a micrometer, measure the outer diameter of the No. 3 gear shift fork.

Standard Outer Diameter:

13.982 to 14.00 mm (0.5505 to 0.5512 in.)

Minimum Outer Diameter:

13.982 mm (0.5505 in.)

If the outer diameter is less than the minimum, replace the No. 3 gear shift fork.

(b) Using a vernier caliper, measure the No. 3 gear shift fork.

Standard Thickness:

9.50 to 9.80 mm (0.374 to 0.386 in.)

If the thickness is not as specified, replace the No. 3 gear shift fork.

6. INSPECT REVERSE SHIFT FORK SHAFT

(a) Using a micrometer, measure the outer diameter of the reverse shift fork shaft.

Standard Outer Diameter:

13.982 to 14.00 mm (0.5505 to 0.5512 in.)

Minimum Outer Diameter:

13.982 mm (0.5505 in.)

If the outer diameter is less than the minimum, replace the reverse shift fork shaft.

7. INSPECT NO. 5 GEAR SHIFT FORK SHAFT

(a) Using a micrometer, measure the outer diameter of the No. 5 gear shift fork shaft.

Standard Outer Diameter:

15.966 to 15.984 mm (0.6286 to 0.6293 in.)

Minimum Outer Diameter:

15.966 mm (0.6286 in.)

If the outer diameter is less than the minimum, replace the No. 5 gear shift fork shaft.

8. INSPECT NO. 2 GEAR SHIFT FORK

(a) Using a vernier caliper, measure the No. 2 gear shift fork.

Standard Inside Diameter and Thickness:

A

9.50 to 9.80 mm (0.374 to 0.386 in.)

B

14.010 to 14.043 mm (0.552 to 0.553 in.)

C

14.70 to 15.30 mm (0.579 to 0.602 in.)

If the inside diameter or thickness is not as specified, replace the No. 2 gear shift fork.

9. INSPECT REVERSE SHIFT FORK

(a) Using a vernier caliper, measure the reverse shift fork.

Standard Inside Diameter and Thickness:

A

4.40 to 4.56 mm (0.173 to 0.178 in.)

B

14.010 to 14.043 mm (0.552 to 0.553 in.)

C

14.7 to 15.3 mm (0.579 to 0.602 in.)

If the inside diameter or thickness is not as specified, replace the reverse shift fork.

10. INSPECT NO. 2 GEAR SHIFT HEAD

(a) Using a vernier caliper, measure the No. 2 gear shift head.

Standard Inside Diameter:

13.994 to 14.054 mm (0.551 to 0.553 in.)

Maximum Inside Diameter:

14.054 mm (0.553 in.)

If the inside diameter exceeds the maximum, replace the No. 2 gear shift head.

11. INSPECT NO. 3 GEAR SHIFT HEAD

(a) Using a vernier caliper, measure the No. 3 gear shift head.

Standard Inside Diameter:

A

15.994 to 16.054 mm (0.63 to 0.632 in.)

B

14.20 to 14.25 mm (0.559 to 0.561 in.)

Maximum Inside Diameter:

A

16.054 mm (0.632 in.)

B

14.25 mm (0.561 in.)

If the inside diameter exceeds the maximum, replace the No. 3 gear shift head.
