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 SpecialTools)on bearing
to allow pressing on both inner and outer bearing
races simultaneously.
B. Use washer and bearing/outer seal tool (see
Special Tools) with a soft face hammer to fully seat
bearing (Fig. 40). After bearing installation, 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. Remove
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 oftube. Use bearing/outer seal tool(see Special
Tools) and soft face hammer to lightly seat seal (Fig.
41). Make sure that shaft and bearings still freely ro-
tate after seal installation.
E. Using the same process, install second outer
sealmakingsureto notcrushtheinstalledouter seal.
Again, make sure that shaft and bearings still freely
rotate.
IMPORTANT: Make sure that all grease is removed
from shaft threads to prevent bearinglock 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.
