14. Install the 35 mm shim (A), and temporary press on

the old ball bearing (B) using the 40 mm inner
driver handle (C), the 30 mm inner bearing driver
attachment (D), and a press (E).

NOTE:

• Use any size of 35 mm shim, and note size you

used. Measurements taken in the following steps
will determine the correct shim to use for final
assembly.

• Make sure to install the ball bearing as shown.

15. Measure the clearance between the old bearing (A)

and the 35 mm shim (B) with a feeler gauge (C).

16. If the measured clearance in step 15 is not within

the standard, select another suitable 35 mm shim
from the table, then go to next step to replace the
35 mm shim and the ball bearing. If the measured
clearance in step 15 is within the standard, go to
next step to replace only the ball bearing.

17. Remove 6th gear and the ball bearing (see step 3

on page 13-119).

18. Remove the 35 mm shim.

19. Repeat step 13 to install 6th gear.

20. Install the correct 35 mm shim (A), then press on

new ball bearing (B) using the 40 mm inner driver
handle (C), the 30 mm inner bearing driver
attachment (D), and a press (E), then recheck the
clearance.

NOTE:

• If necessary, replace the 35 mm shim with the

correct one selected in step 16.

• Make sure to install the ball bearing as shown.

21. Check the clearance between the bearing and the

35 mm shim with a feeler gauge.

22. Securely clamp the countershaft assembly in a

bench vise with wood blocks (A).

23. Tighten new special bolt (B) (left-hand threads).

NOTE: Apply MTF to the bolt threads and flange.

1. Inspect the gear teeth on all synchro hubs and

synchro sleeves for rounded off corners, which
indicate wear.

2. Install each synchro hub (A) in its mating synchro

sleeve (B), and check for free movement. Make
sure to match the three sets of longer teeth (C)
(120 degrees apart) on the synchro sleeve with the
three sets of deeper grooves (D) in the synchro hub.

NOTE:

• Do not install the synchro sleeve with its longer

teeth in the 1st/2nd and 5th/6th synchro hub slots
(E) because it will damage the spring ring.

• If replacement is required, always replace the

synchro sleeve and the synchro hub as a set.

1. Inspect the synchro ring for scoring, cracks, and

damage (A).

2. Inspect the inside of each synchro ring (B) for wear.

Inspect the teeth (C) on each synchro ring for wear
(rounded off).

3. Inspect the teeth (A) on each synchro sleeve and

matching teeth on each gear for wear (rounded off).

4. Inspect the synchro teeth on gear for scoring,

cracks, and damage (A).

5. Inspect the thrust surface (B) on each gear hub for

wear.

6. Inspect the cone surface (C) on each gear hub for

wear and roughness.

7. Inspect the teeth on all gears (D) for uneven wear,

scoring, and cracks.

8. Coat the cone surface of each gear with MTF, and

place its synchro ring on it. Rotate the synchro ring,
making sure that it does not slip.

9. Measure the clearance between each gear (A) and

its synchro ring (B) all around the gear. Hold the
synchro ring against the gear evenly while
measuring the clearance. If the clearance is less
than the service limit, replace the synchro ring and
gear.
