CLEANING AND INSPECTING

„ NOTE: Whenever a part is worn excessively,
cracked, or damaged in any way, replacement is
necessary.

1. Clean the bearings with a clean cloth.

2. Inspect all idler wheel inserts (inner and outer)

for any cracks.

3. Inspect the outer rubber portion of the idler

wheels for cracks and poor bonding.

4. Inspect the plastic insert of each idler wheel for

cracks.

5. Inspect the shaft for wear and damaged threads.

6. Inspect all idler wheel bearings. Turn each bear-

ing (by hand) and if any roughness or binding is

noted, replace the bearing.

7. If a bearing must be replaced, use this proce-

dure.

A. Remove the wheel insert (if applicable) and

the snap ring.

B. Using a hydraulic press, press the bearing out

the inside of the wheel.

C. Press the new bearing (on its outer race) into

the idler wheel.
