Inspect ball bearing (14, fig. 3-60) for galling, roughness, or cage cracks. Remove peck-
ing (13). If damaged, remove retaining rings (12) using truarc pliers and press ball bearing (14) from
motor shaft (11).
(24)
Inspect inner race of cover roller bearing (41) for galling or roughness. If no damage is
apparent and no damage was observed when the outer race was inspected, do not remove bearing from
shaft. If damage was observed on either the inner or outer race, cover roller bearing (11) must be re-
placed. Remove retaining ring (42) and slide cover roller bearing (41) from motor shaft (11).
f.
Reassemble Hydraulic Motor.
NOTE
Use new gaskets and seals, except as noted.
(1)
If the cover roller bearing (41, fig. 3-60) is rough or galled, replace cover roller bearing
(41). Place new cover roller bearing (41) on motor shaft (11) and install retaining ring (42).
(2)
If previously removed, install inner retaining ring (12). If damaged, install a new ball
bearing (14) on motor shaft (11), using an arbor press. CAUTION should be exercised not to deform
inner retaining ring (12) when ball bearing (14) is seated against it. If this occurs, back the ball bearing
(14) off and reseat. Care should be taken to support the ball bearing (14) in the arbor press to prevent
deformation of the ball bearing (14). Heating the bearing in hot oil will aid in a smooth bearing install-
ation. install outer retaining ring (12).
(3)
Install motor shaft (11), ball bearing (14) with packing (13), two retaining rings (12),
retaining ring (42), and cover roller bearing (41) through the front face of the mounting flange assem-
bly (8). (Refer to fig. 3-77.) The ball bearing (14, fig. 3-60) should fit snugly in the mounting flange
assembly (8). If the ball bearing (14) doesn’t seat easily, heat the mounting flange assembly (8) in hot
oil and seat ball bearing (14) in proper position. Do not drive the ball bearing (14) into place. Do not
use the shaft seal assembly (4) to force the ball bearing (14) into the seat. After ball bearing (14) is
seated, check for free running by rotating motor shaft (11).
