2.4 Align anti-rotation tabs of wiper
seals vertically and space axially
approximate distance to match ID
of bearing. Position such that the
lower wiper seal is 25 to 50 mm
(1 to 2 inches) above the mounting
plate.
2.5 Place one half of carrier assembly
onto shaft, ensuring that anti-
rotation tabs are fully engaged to
the ID of the bearing. The spheri-
cal section of the carrier assembly
should point down and the straight
section of the carrier should point
up.
2.6 Join the mating half in the same
orientation and secure bearing
assembly by installing the four (4)
cap screws. Tighten cap screws to
a torque value of 2.3 N-m
(20 in-lbs).
2.7 Apply a light coating of high
temperature grease in the O-ring
groove on the outside of the carrier
assembly. Place O-ring cord in the
groove so the two ends meet on
either side of the anti-rotation pin.
The grease should hold the O-ring
in place.
