Mainshaft input gear bearing pre-load
1. Position mainshaft input gear assembly in main
casing.
2. Fit mainshaft input gear bearing housing
ensuring that reference marks are aligned.
3. Fit 2 M10 x 25 mm bolts and tighten to 25 Nm
(18 lbf.ft).
4. Position suitable DTI with stylus of gauge
contacting end of mainshaft, push mainshaft
rearwards and zero gauge.
5. Push mainshaft forwards and note gauge
reading.
6. Calculate thickness of shim required using the
formula A + B + C = D where:
A = Thickness of installed shim - 3.15 mm
(0.12 in)
B = Recorded end-float
C = Required pre-load - 0.05 mm (0.002 in)
D = Thickness of shim required
7. If an alternative shim is required to establish
correct end-float, proceed as follows:
NOTE: Do not remove mainshaft input
gear bearing housing if bearing pre-load is
correct.
8. Remove 2 bolts, remove mainshaft input gear
bearing housing.
