5. Clean the roller shaft and all surfaces on the inside of the roller tube. Inspect
components for wear or damage. Also, carefully inspect the seating surface
and threads of the bearing locknuts. Replace all the components that were
damaged.
1. Install the inner seals into the roller tube and ensure that the seal lip (and
garter spring) faces end of the tube. Use the inner seal tool (refer to
Tools (page 7–5)) and soft-faced hammer to fully seat seals against the roller
shoulder (Figure 237). Apply a small quantity of grease around the lip of both
inner seals after installation.
During assembly process, frequently check that the bearings
rotate freely and do not bind. If there is any binding, remove the
components and install it again correctly.
2. Install a new bearing and the outer seals into one end of the roller tube as
follows:
A. Position a new bearing into one end of the roller tube. Use the
bearing/outer seal tool (refer to
soft-faced hammer to fully seat bearing against the roller shoulder
238). After the bearing installation, ensure that the bearing rotates freely
without binding.
B. Apply a small quantity of grease around the lip of both outer seals.
