INSPECTION

INPUT SHAFT





1. Check the outside diameter of the needle bearing mounting portion for damage, abnormal wear and seizure.
2. Check the splines for damage and wear.
3. Check that the helical gear teeth surfaces are not damaged or worn.

NEEDLE ROLLER BEARING
1. Combine the needle roller bearing with the input shaft or bearing sleeve and gear, and check that it rotates smoothly without noise or play.
2. Check the needle roller bearing cage for deformation.

SYNCHRONIZER RING





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





3. Force the synchronizer ring toward the clutch gear and check clearance A. If A is less than the limit, replace.
Minimum limit: 0.5 mm (0.020 inch)

OUTER SYNCHRONIZER RING/INNER SYNCHRONIZER RING/SYNCHRONIZER CONE

CAUTION: When any of the outer ring, inner ring or cone has to be replaced, replace them as a set.





1. Check to ensure that the clutch gear tooth surface and cone surface are not damaged and broken.





2. Install the outer ring, inner ring and cone, press them against the gear, and check clearance A. If A is less than the limit, replace.
Minimum limit: 0.5 mm (0.020 inch)

SYNCHRONIZER SLEEVE AND HUB





1. Combine the synchronizer sleeve and hub, and check that they slide smoothly.
2. Check that the sleeve is free from damage at its inside splines ends.

SYNCHRONIZER SPRING
Check that the spring is not sagging, deformed or broken.

SPEED GEARS





1. Check that the helical and clutch gear tooth surfaces are not damaged or worn.
2. Check that the synchronizer cone surfaces are not roughened, damaged or worn.
3. Check that the gear inside diameter and front and rear surfaces are not damaged or worn.
