10. Select the correct thickness of aluminum shims
(18) to give the shim set established in Step 9.
Check the thickness of the shims with an outside
micrometer (FIGURE 10, page 30). Place the
shims on the end of the housing, matching the
pointed section of the shims with the contour of the
housing. Remove bearing spacers from the
discharge end bearing carrier, FIGURE 7-
7
,
page 34, and place them over the shaft
extensions, grooved end toward the rotor. Be sure
the spacer fits solidly against the rotor. If
measurements in
Step 7 differ, make sure the bearing spacer is
placed over its respective shaft extension to
assure proper end clearance of each rotor.
11. Coat the I.D. of the shaft seals in the discharge
end bearing carrier with
“Moly” type grease.
Remove bearings from the carrier. Tag bearings
so they will be reassembled in the same bearing
bore from which the measurement was made.
Match the cavity of the carrier, 34, page
29, with the discharge opening of the housing
Figure 7-11, and lower the carrier, suspended
plumb, in place on the housing. Be careful not to
damage I.D. of the shaft seal by the shaft exten-
sion. Be sure there are no shaft shims in place
during this operation as sharp edges of shims will
damage the seals. Tighten the carrier to housing
screws evenly to prevent damage to dowel pins.
12. With the dial indicator attached as shown in
FIGURE 7 - 12, check the total end clearance.
Set the indicator on zero and lift the rotor with a
hoist until the end of the rotor strikes the face
of the discharge end bearing carrier. The reading
of the indicator will be the total end clearance and
should match dimensions listed in the clearance
chart,
FIGURE 7- 8, page 35. If the indicator reading
differs from the chart and allowable tolerance,
repeat Steps 9 and 10 as well as check for burrs
giving false readings.
Due to allowable machining tolerance
of the rotor lengths, there may be
cases where one rotor will be within
limits and the other slightly over or
under.
13. All internal oil seals are directional Impro seals.
They must be installed in the correct location and
with proper orientation.
Apply RTV sealant below the o-ring. Expulsion
port positioned towards the bottom of the unit.
