CLEANING AND INSPECTION
1.
For general cleaning and inspection instructions, refer to WP 0021 00.
2.
Inspect two bearing assemblies (9) and bearing (8) (TM 9-214). Replace bearing assemblies (9) or
bearing (8) if damaged.
3.
Measure inside diameter of inner race on two bearings (10). Refer to table 1, Wear Limits, for
measurements. Replace bearings (10) if not within wear limits.
4.
Measure inside diameter of bearing (8). Refer to table 1, Wear Limits, for measurements. Replace
bearing (8) if not within wear limits.
5.
Measure outside diameter of bearing (8). Refer to table 1, Wear Limits, for measurements. Replace
bearing (8) if not within wear limits.
6.
Inspect helical pinion gear (4) for chips, breaks, cracks, burrs, or uneven wear. Replace helical
pinion gear (4) and helical drive gear (1) if chipped, broken, cracked, burred, or worn unevenly.
7.
Measure outside diameter of smaller helical pinion shaft (6). Refer to table 1, Wear Limits, for
measurements. Replace helical pinion gear (4) and helical drive gear (1) if not within wear limits.
8.
Measure outside diameter of larger helical pinion shaft (5). Refer to table 1, Wear Limits, for
measurements. Replace helical pinion gear (4), 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 (7) for chips, cracks, or distortion. Replace sleeve (7) if chipped, cracked, or distorted.
