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 (page
(Figure 311). Make sure that shaft and bearings 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.
Make sure that all grease is removed from shaft threads to prevent
bearing lock nut loosening.
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 during nut installation. Torque lock nuts from 68
to 81 N·m (50 to 60 ft-lb).
7. If set screw was removed from either end of roller shaft, apply Loctite #242
(or equivalent) to threads of removed set screw and install into roller shaft.
Tighten set screw until it bottoms in shaft and is recessed in shaft.
When roller assembly is installed to cutting deck, make sure that
grease groove in each roller mount aligns with the grease hole in
each end of roller shaft.
Note: After roller is installed to cutting deck, 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
0.68 N·m (5 in-lbs) resistance.
