Gear Dog/Gear Dog Hole Damage
Visually inspect the gear dogs [A] and gear dog holes [B].
Replace any damaged gears or gears with excessively worn dogs or
Ball and Needle Bearing Wear
Do not remove the bearings for inspection.
Check the ball bearings.
Since the ball bearings are made to extremely close tolerances, the
wear must be judged by feel rather than measurement. Clean each
bearing in a high-ﬂash-point solvent, dry it (do not spin the bearing
while it is dry), and oil it with engine oil.
Spin [A] a bearings by hand to check its condition.
If the bearings are noisy, do not spin smoothly, or have any rough
spots, replace them.
Check the needle bearing.
The rollers in a needle bearing normally wear very little, and wear
is difﬁcult to measure. Instead of measuring, inspect the bearing for
abrasion, color change, or other damage.
If it is any doubt as to the condition of a needle bearing, replace it.
Oil Seal Inspection
Inspect the oil seals.
Replace it if the lips are misshapen, discolored (indicating that the
rubber has deteriorated), hardened or otherwise damaged.
