E) Remove plug on the thrust bearing housing.
Loosen the socket head cap screw that is located
underneath the plug. This secures the inner races
of the thrust bearings to the spindle.
F) Remove bolts that hold the thrust bearing hous-
ing to the compressor. Insert two of the bolts into
the threaded jacking holes to assist in removing
the bearing housing from the compressor. When
the housing is removed, there will be shims be-
tween the spindle and thrust bearings. These
control the clearance between the shelf and
gate rotor blades. These must be kept with their
respective parts for that side of the compressor.
G) Remove the bolts from the roller bearing housing.
After the bolts have been removed, the housing
can be removed from the compressor.
H) To remove the gate rotor support, carefully move
the support opposite the direction of rotation
and tilt the roller bearing end towards the suc-
tion end of the compressor. The compressor
input shaft may have to be turned to facilitate the
removal of the gate rotor support. On dual gate
versions, repeat the procedure for the remaining
gate rotor support assembly.
