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

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.

9. Using a soft metal drift, carefully drive input

gear bearing track out of bearing housing,
remove shim.

CAUTION: If bearing track is damaged
during this operation, a new track must be
fitted.

10. Select required shim from the range available.

NOTE: Shims are available from 3.15 to
4.00 mm (0.12 to 0.16 in) thickness rising
in increments of 0.5 mm (0.002 in).

11. Fit selected shim and using a suitable mandrel,

fit input gear bearing track.

12. Fit mainshaft input gear bearing housing and

temporarily secure using 2 M10 x 25 mm bolts
tightened to 25 Nm (18 lbf.ft) .
