attachment (D), and a press (E).
NOTE:
• If necessary, replace the 35 mm shim with the
correct one selected in step 15.
• Make sure to install the ball bearing as shown.
19. Check the clearance between the bearing and the
35 mm shim with a feeler gauge.
20. Securely clamp the countershaft assembly in a
bench vise with wood blocks (A).
21. Tighten new special bolt (B) (left-hand threads).

Example of synchro sleeve teeth and gear teeth
1. Inspect the gear teeth on all synchro hubs and
synchro sleeves for wear (rounded off corners).
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 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 rings 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.
