3. From the roller tube end with only the inner seal
installed, carefully install the roller shaft into the roller
tube. Make sure that seals are not damaged as shaft is
installed.
4. Install new bearing and outer seals into second end
of roller tube:
A. Position a second new bearing to roller shaft and
tube. Position washer (see Special Tools in this
chapter) on bearing to allow pressing on both inner
and outer bearing races simultaneously.
B. Use washer and bearing/outer seal tool (see
Special Tools in this chapter) with a soft face hammer
to fully seat bearing (Fig. 30). After bearing installa-
tion, make sure that shaft freely rotates and that no
binding is detected. If necessary, lightly tap bearing
and/or shaft ends to align shaft and bearings. Re-
move washer from roller.
C. Apply a small amount of grease around the lip of
both outer seals.
D. Carefully install first outer seal into roller tube
making sure that seal lip (and garter spring) faces
end of tube. Use bearing/outer seal tool (see Special
Tools in this chapter) and soft face hammer to lightly
seat seal (Fig. 31). Make sure that shaft and bear-
ings still freely rotate after seal installation.
E. Using the same process, install second outer
seal making sure to not crush the installed outer seal.
Again, make sure that shaft and bearings still freely
rotate.
IMPORTANT: Make sure that all grease is removed
from shaft threads to prevent bearing lock nut loos-
ening.
5. Thoroughly clean threads on both ends of roller
shaft.
NOTE: If original bearing lock nut(s) are being used,
apply Loctite #242 (or equivalent) to threads of lock
nut(s).
6. Install bearing lock nut onto each end of the roller
shaft. Make sure that outer seals are not damaged dur-
ing nut installation. Torque bearing lock nuts from 50 to
60 ft- -lb (68 to 81 N- -m).
7. If grease fittings were removed from end of roller
shaft, install fittings in shaft.
NOTE: After roller is installed to cutting unit, lubricate
roller grease fittings, rotate roller to properly distribute
grease in bearings and clean excess grease from roller
ends. A properly assembled roller should rotate with
less than 5 in--lb (0.68 N--m) resistance.
