Fig. 104: Inspecting The Gear Hub Thrust Surface

4. Inspect the cone surface (E) on each gear hub for wear and roughness.

5. Inspect the teeth on all gears (F) for uneven wear, scoring, galling, and cracks.

6. Coat the cone surface of each gear (E) with oil, and place its synchro ring on it. Rotate the synchro ring,

making sure that it does not slip.

7. 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.
