CLEANING AND INSPECTION
1. Thoroughly clean and inspect each part. If inspection
shows that any parts are bent, broken or damaged, those
parts should be repaired or replaced.
2. See Figure 2-85. Inspect fork tube bushing (24) and
bushing guide (14) and replace as required.
3. Always replace oil seals (12) and o-rings (6).
4. Check dust cover (9) where it rubs on fork tube. The dust
cover should present a good continuous seal and not show
excessive wear.
5. Check the slider tube (1) where it rubs on dust cover. The
tube should show a bright, shining surface, free of scoring
or abrasions.
6. If springs (4) are broken, replace springs.
7. If a fork tube or slider (16, 17) is bent or damaged, replace
it.
8. Replace all other worn or damaged components as
necessary.
