b. Cleaning and Inspection
1. For general cleaning instructions, refer to para. 2-8.
2. Inspect two bearing assemblies (5) and bearing (7) (TM 9-214). Replace bearing assemblies (5) or
bearing (7) if damaged.
3. Measure inside diameter of inner race on two bearings (6). Refer to table 10-1, Wear Limits, for
measurements. Replace bearings (6) if not within wear limits.
4. Measure inside diameter of bearing (7). Refer to table 10-1, Wear Limits, for measurements. Replace
bearing (7) if not within wear limits.
5. Measure outside diameter of bearing (7). Refer to table 10-1, Wear Limits, for measurements.
Replace bearing (7) if not within wear limits.
6. Inspect helical pinion gear (10) for chips, breaks, cracks, burrs, or uneven wear. Replace helical
pinion gear (10) and helical drive gear (1) if chipped, broken, cracked, burred, or worn unevenly.
7. Measure outside diameter of smaller helical pinion shaft (9). Refer to table 10-1, Wear Limits, for
measurements. Replace helical pinion gear (10) and helical drive gear (1) if not within wear limits.
8. Measure outside diameter of larger helical pinion shaft (8). Refer to table 10-1, Wear Limits, for
measurements. Replace helical pinion gear (10), bevel gear (2), and pinion (3) if not within wear
limits.
9. Inspect bevel gear (2) for chips, breaks, cracks, burrs, or uneven wear. Replace bevel gear (2) and
pinion (3) if chipped, broken, cracked, burred, or worn unevenly.
10. Inspect sleeve (4) for chips, cracks, or distortion. Replace sleeve (4) if chipped, cracked, or distorted.
11. Measure inside diameter of sleeve (4). Refer to table 10-1, Wear Limits, for measurements. Replace
sleeve (4) if not within wear limits.
