1. Check the outer surface of the input shaft where the needle bearing is mounted for damage, abnormal wear and seizure [portion A].
2. Check the splines for damage and wear.

Needle Bearing





1. Combine the needle bearing with the shaft or bearing sleeve and gear and check that it rotates smoothly without abnormal noise or play.

Synchronizer Ring





1. Check the clutch gear teeth for damage and breakage.
2. Check the internal surface for damage, wear and broken threads.

CAUTION: When replacing, replace the synchronizer hub and sleeve as a set.

Synchronizer Key And Spring





1. Check for wear of the synchronizer key center protrusion.
2. Check the spring for weakness, deformation and breakage.

Speed Gears
