GATE ROTOR THRUST BEARING INSTALLA-
TION
A) For installation of thrust bearings on VSG and
VSSG 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
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 clear-
ance, refer to section INSTALLATION (All
VSG Models).
B) For installation of thrust bearings on VSG 301-
701 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
towards 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 com-
pressor lubricating oil should be used to
ease the installation of the bearings 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 clear-
ance, refer to section INSTALLATION (All
VSG Models).
