Remove Seals and Bearings
1. Clean inside of roller around both adjusting nuts and
roller shaft ends. Both areas should be free of dirt and
debris.
2. Remove adjusting nut from one end of the roller
shaft. On the sectional roller, remove both adjusting nuts
from each end of the roller.
NOTE: When disassembling a full roller, pour the oil
from inside the roller into a suitable container.
3. Keep roller level and slide the shaft with the remain-
ing adjusting nut out of the roller. On the sectional roller,
slide both sectional rollers of the shaft.
4. Secure roller in a vise.
5. Remove outer seals.
6. Remove both bearing cones. On the sectional roller,
remove all four bearing cones.
Note: An electric arc welder can be used to shrink the
bearing cup to simplify its removal. Only a small arc in
one location on the cup is required.
7. Remove both bearing cups from the roller. Remove
both inner seals installed on the full roller. On the sec-
tional roller, remove all four bearing cups.
8. Discard seals and bearings.
