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 [B] 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 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.

○Since the bearing are packed with grease and sealed, lubrication is not required.
