Input Shaft, Adjusting



Input Shaft, Adjusting

Note: The input shaft must be re-adjusted if the transmission housing, input shaft or ball bearing is replaced.

Special tools and equipment
- 30-100 press tube
- 3167 spacer gauge
- Depth gauge






- Clamp input shaft in vice using protective jaws -A-.
- Place 3167 spacer gauge onto 3rd gear.
- Place transmission housing over input shaft onto spacer gauge.

Calculating dimension -x






- Place depth gauge onto transmission housing and measure to lower circlip groove of input shaft.
- Dimension in the example: -a- = 28.50 mm (1.122 inch)






- Place depth gauge onto transmission housing and measure to seating surface for ball bearing.
Measurement in the following example: -b- = 26.80 mm (1.055 inch)

Determining circlip thickness behind the input shaft ball bearing
Formula: x = a - b
Example:
Dimension -a-28.50 mm
Dimension -b-26.80 mm
Dimension -x-1.70 mm (thickness of circlip)
Determine circlip thickness according to table below.

Available circlips

Dimension -x- (mm) Thickness (mm)

1.48 - 1.56 1.54
1.57 - 1.65 1.63
1.66 - 1.74 1.72
1.75 - 1.83 1.81
1.84 - 1.92 1.90
1.93 - 2.01 1.99
2.02 - 2.10 2.08
2.11 - 2.20 2.17


Determining circlip thickness in front of input shaft ball bearing
- Drive rear circlip (as calculated) and ball bearing onto input shaft using 30-100 press tube.






- Determine thickest circlip which can still just be installed.
- Determine circlip thickness according to table.
Part number, Refer to parts supplier.
