NOTICE
Do not remove the bearings for inspection. Removal may damage them.

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.
If bearing play, roughness, or binding is found, replace the bearing.
If the seal is torn or is leaking, replace the bearing.
