1.06 GATE ROTOR THRUST
BEARING INSTALLATION
A) For installation of thrust bearings on VSS
and VSR units:
1) Install bearings (126) in the housing so
the bearings are face to face.
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
bearings into the housing.
2) Center the bearing retainer ring on hous-
ing, use Loctite
®
242-thread locker and
evenly tighten the bolts to the recom-
mended torque value.
3) For installation of the bearing housing
and the setting of the gate rotor blade
clearance, refer to section 1.02.
B) For installation of thrust bearings on VSM
units:
1) 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.
2) The bearing with the retainer should be
placed in the housing first, retainer to-
wards the support. Install the second
bearing. The bearings should be posi-
tioned 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 gate rotor support.
3) Install the bearing retaining snap ring.
4) For installation of the bearing housing
and the setting of the gate rotor blade
clearance, refer to section 1.02A.
