4.08 COMMAND SHAFT BEARING
AND O-RING SEAL
REASSEMBLY
A) Install new O-ring seal in housing and lu-
bricate the O-ring with clean compressor oil.
A vent hole is provided in the command shaft
bearing housing to allow any refrigerant and
oil that may leak past the O-ring seal to vent
to atmosphere and not into the slide valve
motor housing. Install snap ring retainer and
washer on the command shaft.
B) Remove any burrs from the command shaft
to prevent damage to the O-ring when as-
sembling. Press the command shaft bearing
onto the command shaft. Insert the com-
mand shaft into the housing appling pres-
sure on outer race of bearing. Make sure the
bearing is fully seated in the command shaft
housing. Install the snap ring retainer in
the command shaft housing.
C) Install command shaft assembly as outlined
in section 4.02.
4.09 DISCHARGE MANIFOLD
REMOVAL
A) Remove both control actuators and command
shaft assemblies as outlined in sections 4.01
and 4.05.
B) On VSS and VSR compressors, remove the
discharge spool between the manifold and
separator. Remove one bolt from each side
of the discharge manifold and install (2)
guide rods approximately 6” long, to sup-
port the manifold. Remove the remaining
bolts (note length and location of bolts) and
take off the discharge manifold.
Note: Mainfold has dowel pins to locate it
on the compressor housing. Therefore, re-
move manifold straight back approximately
1” as not to break dowel pins.

NOTE:
When removing the discharge manifold on VSM
compressor the compressor must be properly sup-
ported to keep the compressor from moving when
the manifold is removed.
C) On VSM compressors unbolt the discharge
flange from the discharge manifold.
D) Remove one bolt from each side of the dis-
charge manifold and install (2) guide rods
approximately 6” long, to support the mani-
fold. Remove the remaining bolts (note
length and location of bolts) and take off the
discharge manifold.
4.10 DISCHARGE MANIFOLD
INSTALLATION
A) Install (2) guide rods to position the dis-
charge manifold. Install a new manifold
gasket and the discharge manifold. Install
the dowel pins and bolts, tighten manifold
bolts to the recommended torque value.
B) On VSS and VSR compressors install the
discharge spool or elbow between the dis-
charge manifold and oil separator with new
gaskets. When installing the discharge el-
bow tighten the bolts to the correct torque
on the manifold flange first before tighten-
ing the separator flange bolts. Install the
drain plug in the bottom of the discharge
manifold.
