CLEANING AND INSPECTING

NOTE: Whenever a part is worn excessively,

cracked, or damaged in any way, replacement is
necessary.

2. Inspect each idler wheel for cracks or damage.

3. Inspect the bushings (located in the arm pivot area)

for wear or damage.

4. Inspect all welds and the tubing of the upper arm for

cracks or unusual bends.

5. Inspect the two adjusting cams for damage.

6. Rotate the idler wheel bearings (by hand) and check

for binding or roughness.

7. If a bearing must be replaced, use this procedure.
