front bearing cap to bearing holder. Remove bearing
holder from rotor shaft assembly.
11. Remove bearings from rotor shaft:
A. Remove outer retaining rings from shaft.
B. Press bearings from shaft.
C. Remove front bearing cap and inner retaining
rings from shaft if necessary.
12.Inspect rotor shaft and bearing bores of bearing
holder and inner housing for wear or damage. Replace

Installation (Fig. 6)
1. Install bearings onto rotor shaft:
A. Install inner retaining rings into shaft groove if
they were removed.
B. Make sure that front bearing cap (item 6) is
placed on rotor shaft between bearing locations.
C. Install bearings onto shaft by pressing on inner
race. Make sure that bearings are seated against in-
ner retaining ring.
D. Install outer retaining rings to secure bearings on

−
oily
cleaner. After cleaner dries completely, apply Loctite
Primer N 7649 (or equivalent) to bearing bores. Allow
Primer to dry completely.
3. Thoroughly clean OD of bearings on rotor shaft. Ap-

bearings.
4. Slide bearing holder onto bearing on rotor shaft.
Position front bearing cap (item 6) to bearing holder and
secure with four (4) flange head screws.
5. Install rotor shaft assembly into inner housing mak-
ing sure that bearing is fully seated in housing bearing
bore. Make sure that bearing holder slides fully into in-
ner housing and that rotor shaft rotates freely.
6. Install four (4) cap screws to secure bearing holder
to inner housing. Tighten screws in three (3) equal steps
and in a crossing pattern. Final torque on screws should
be from
180 to 210 in
