Swingarm Bearing, Sleeve Inspection
Caution: Do not remove the bearings for inspection. Removal may damage them.
- Inspect the needle bearings [A] and ball bearing installed in the swingarm.
The rollers and ball in a bearing normally wear very little, and wear is difficult to measure. Instead of measuring, visually inspect the bearing for abrasion, discoloration, or other damage.
If the needle bearing and sleeve show any sings of abnormal wear, discoloration, or damage, replace them as a set.
- Turn the bearing in the swingarm back and forth [A] while checking for plays, roughness, or binding.
If the bearing play, roughness, or binding is found, replace the bearing.
- Examine the bearing seal [B] for tears or leakage.
If the seal is torn or is leaking, replace the bearing.
Swingarm Bearing Lubrication
Note: Since the bearings are packed with grease and sealed, lubrication is not required.
