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

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 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).
