Input Shaft Inspection

INSPECTION

INPUT SHAFT





- Check the needle bearing mounting portion of the shaft for damage, wear and seizure.
- Check the splines for damage and wear.

NEEDLE BEARING

- Combine the needle bearing with the input shaft and gears and check that it smoothly rotates without noise or play.
- Check the needle bearing retaining sleeve for deformation.

SPEED GEARS





1. Check that the helical and clutch gears of each speed gear are not damaged or worn in the tooth surface.
2. Check that the synchronizer cone of each speed gear is not roughened, damaged or worn in the surface.
3. Check that the inner, front and rear surfaces of each speed gear are not damaged or worn.

SYNCHRONIZER RING





1. Check that the outer synchronizer ring clutch gear is free of damage.
2. Check that the synchronizer rings and synchronizer cones are free of damage or wear in the contact surface and broken screw threads.
3. Check that the outer synchronizer ring and synchronizer key contact surface is free of damage and wear.





4. Join the outer and inner synchronizer rings and synchronizer cone together and check clearance
"A" shown. If "A" is less than the limit value, replace them.

Limit A (from back of outer ring to clutch gear): 0.5 mm (0.02 inch)


SYNCHRONIZER SLEEVE AND HUB





- Combine the synchronizer sleeve and hub, and check that they slide smoothly.
- Check that the sleeve is free of damage at its inside spline ends.
