10. Install clamp ring (253B) with bolts (236A).
Tighten bolts in a crisscross pattern. Check shaft
for free turning. Refer to
Table 9 for bolt torque
values (Fig. 130).
11. Install new O-ring (496).
12. Install outboard labyrinth oil seal (332A) into
bearing housing (134). It is an O-ring fit. Position
the labyrinth seal drain slots at the bottom
6 o’clock position (Fig. 130).
NOTE: See Appendix IV or VIII for further
instructions on Labyrinth Seal installation.
NOTE: Make sure the keyway edges are free of
burrs.
NOTE: Cover the keyway lengthwise with a
piece of electrical tape prior to installing the
labyrinth seal. This will protect the O-rings.
13. Coat outside of bearing housing (134) with oil.
14. Coat all internal surfaces of bearing frame (228A)
with oil.
15. Install shaft assembly into frame (228A), making
sure to leave approximately 0.125 in. (3.175 mm)
clearance between the face of the bearing
housing and bearing frame. Check shaft for free
turning (Fig. 131).
