For installation of thrust bearings on VSM 301-
701 units
24. Install retainer in the back of the inner race of one
of the thrust bearings. The back of the inner race is
the narrower of the two sides.
25. The bearing with the retainer should be placed in
the housing first, retainer towards the support.
Install the second bearing. The bearings should be
positioned face to face. This means that the larger
sides of the inner races are placed together. A light
application of clean compressor lubricating oil
should be used to ease the installation of the bear-
ings into the gaterotor support.
26. Install the bearing retaining snap ring.
Gaterotor Roller Bearing Removal
27. Remove the snap ring (131), which retains the roll-
er bearing in the bearing housing, see Figure 5-54.
28. Remove the roller bearing (125) from the bearing
housing (112).
29. Use a bearing puller to remove the roller bearing
race (125) from the gaterotor support (110).
Gaterotor Roller Bearing Installation
30. Match up the part numbers on the inner race to
the part numbers outer race. Press the bearing race
(numbers visible) onto the gaterotor support.
31. Install the outer bearing into the bearing housing
so the numbers match the numbers on the inner
race. Install the snap ring retainer in the housing.
The bevel on the snap ring must face away from the
roller bearing.
