5-20
5.4.6 Motor Bearing Retainer
a) Apply oil on the planetary ring of the motor bearing
[613] and the lip part (in contact with the shaft) of the
motor oil seal [617].
b) Screw two stud bolts (safety bolts) into appropriate top
bolt holes.
c) Apply oil on the gasket [615] and attach it to the bearing
retainer [614] so that the bolt holes allow the stud bolt
to enter.
d) While holding the bearing retainer with both hands,
mount it in the motor casing (picture to the right).
Push the motor rotor shaft [607] into the bearing that
has already been mounted in the bearing retainer.
As the shaft is pushed in, the bottom end of the spigot section hits the flange hole in the motor
casing. In that case, further push in the spigot section while bring it up, it can be mounted onto the
flange surface.
e) After slightly tightening the motor oil seal retainer fastening bolts [619] and fit the hexagonal bar
wrench to the motor rotor mounting bolt [609], ensure that the shaft can be turned by hand
(following picture to the left), tighten them with the specified torque (following picture to the right).
5.4.7 Motor End Cover
a) Apply oil on the gasket [621].
Attach the gasket to the flange of motor end cover [620] while allowing it to the bolt holes.
b) While fitting the motor end cover to the motor bearing retainer (following picture to the left), screw
in the eight bolts [622], and then tighten them with the specified torque (following picture to the
right).
