1.02B INSTALLATION (All VSM Mod-
els)
A) Install the gate rotor support. Carefully tilt
the roller bearing end of the gate rotor sup-
port towards the suction end of the compres-
sor. The compressor input shaft may have
to be rotated to facilitate the installation of
the gate rotor support.
B) Install the roller bearing housing with a new
O-ring. Tighten the bolts to the recom-
mended torque value.
C) Install the spindle with shims and o-ring,
tighten the bolts to the recommended torque
value, measure the clearance between the
shelf and blade.
D) Check the clearance between the entire gate
rotor blade and the shelf, rotate the gate ro-
tor to find the tightest spot. It should be
between 0.003”-0.004”. Make adjustments,
if necessary. It is preferable to shim the gate
rotor blade looser rather than tighter against
the shelf.
Important: Read note on page 42.
E) Once the clearance is set remove the spindle.
Install new o-ring, apply Loctite 242 thread
locker to the socket head cap screw clamp-
ing the thrust bearings to the spindle. Torque
all bolts to the recommended torque values.
F) Install side covers with new gaskets. Tighten
bolts to the recommended torque value. The
unit can now be evacuated and leak checked
as outlined in section 0.03.
