TM 5-3805-262-34CLEANING, INSPECTION, AND REPAIR (SHEET 2 OF 2)d. Inspect gears (13, 14, 22, and 23) and connecting shaft (21) for grooves atbearing surfaces. Check both ends of gear teeth for wear especially near out-side diameter of gears. Carefully check base of gear teeth at both ends andbearing area of gear shaft for a dull surface such as made by fine sandpaper;this condition indicates wear caused by small particles. Check gear teeth forcracks, breaks, or other damage. Replace gears if any of these conditions areseen.e. Inspect port end cover (3), gear housing (9), bearing carrier (15), gear hous-ing (24), and shaft end cover (34) for cracks, breaks, or other damage. Checkmachined surfaces for deep scratches or grooves. Check gear housings (9 and24) area in which gears move for grooves or scoring and for dull surface suchas made by fine sandpaper indicating wear caused by small particles. Replaceany part if any of these conditions are seen.f. Check thrust plates (4, 16, and 28) for scratches or grooves, narrow bandaround bores having a dull surface such as made by fine sandpaper indicatingwear caused by small particles, and deformed lubrication slots larger at endthan in center. If any of these conditions are seen, replace thrust plate.g. Check dowel pins (8, 12, 20, and 26) for deformation, distortion, or otherdamage. Replace by grasping dowel pin using slip joint pliers and twisting outof plate. Press new dowel pins into plate using hydraulic press until dowelpin is seated.h. Check bearings (6, 18, and 30) for grooves, scratches, cracks, or other dam-age. If gears (13 and 14) or gears (22 and 23) are replaced, associated bear-ings must also be replaced. Refer to following steps for removal and replace-ment.i. If bearings (6) require replacement, pull bearings from port end cover (3)using a puller. Remove and discard seal (7) using suitable tool. Put new seal(7) in bore. Put port end cover in hydraulic press and press new bearings (6)into port end cover.j. If bearings (18) require replacement, pull bearings from bearing carrier (15)using a puller. Remove and discard seals (19) using suitable tool. Put newseal (19) in bore. Put bearing carrier in hydraulic press and press two newbearings (18) into bores. Turn bearing carrier over and repeat above procedureto install remaining seal (19) and two bearings (18).k. If bearings (30) require replacement, pull bearings from shaft end cover (34)using a puller. Remove and discard seal (31) using suitable tool. Put new seal(31) in bore. Put shaft end cover in hydraulic press and press two new bear-ings (30) into bores.4-271
