CLEANING, INSPECTION, AND REPAIR (SHEET 2 OF 2)
d. Inspect gears (13, 14, 22, and 23) and connecting shaft (21) for grooves at
bearing 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 and
bearing 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 for
cracks, breaks, or other damage. Replace gears if any of these conditions are
seen.
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. Check
machined surfaces for deep scratches or grooves. Check gear housings (9 and
24) area in which gears move for grooves or scoring and for dull surface such
as made by fine sandpaper indicating wear caused by small particles. Replace
any part if any of these conditions are seen.
f. Check thrust plates (4, 16, and 28) for scratches or grooves, narrow band
around bores having a dull surface such as made by fine sandpaper indicating
wear caused by small particles, and deformed lubrication slots larger at end
than 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 other
damage. Replace by grasping dowel pin using slip joint pliers and twisting out
of plate. Press new dowel pins into plate using hydraulic press until dowel
pin 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 new
seal (19) in bore. Put bearing carrier in hydraulic press and press two new
bearings (18) into bores. Turn bearing carrier over and repeat above procedure
to 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.
