Service
REMOVAL (ALL VSG 301-701 MODELS)
The removal of the gate rotor assembly for the VSG
301-701 compressors is similar for the VSG 901-
2101 compressors. The inner races are secured to
the stationary bearing spindle.
A) Prepare the compressor for servicing.
B) Remove the upper bolt from the side cover and
install a guide stud in the hole. Remove the
remaining bolts and side cover. There will be
some oil drainage when the cover is removed.
C) The side cover that contains the suction strainer
should have the suction line properly supported
before the bolts securing the line to the cover
can be removed. After the line is removed, the
cover can be removed per paragraph B.
D) Turn the main rotor so the driving edge of the
groove is between the top of the shelf or slightly
below the back of the gate rotor support. At
this point install the gate rotor stabilizing tool.
