(Only clutch assemblies fitted with thrust washer 9A)
Later clutch assemblies feature an additional thrust washer
9A. If any of the components listed below are to be renewed,
the end float of gear 5 must be measured and reset as
required:
Item
B Shaft assembly
5 Gear and plate carrier assembly
6,7 Thrust washer assembly
9,10 Thrust washer assembly
4 4WD transfer gear or spacer as applicable
Check and reset the endfloat of gear 5 as follows:
1 Temporarily fit thick thrust washer 11, thin thrust washer
9A, thrust bearing 10 and thin thrust washer 9. Fit
needle roller bearing 8.
2 Temporarily fit the gear and plate carrier assembly 5. Fit
the thin thrust washer 6 and thrust bearing 7 followed
by the remaining thrust washer 6.
3 Temporarily fit the 4 wheel drive transfer gear 4 onto the
layshaft spline. Make sure that the gear is fitted the
correct way round. 2 wheel drive machines have a
spacer fitted instead of a gear. Fit the circlip 3.
4 Make sure that the 4 wheel drive gear (or spacer) is fully
seated against circlip 3. Measure the end float of gear 5.
It must be between 0.01 to 0.15 mm (0.0004 to 0.006 in)
If the end float requires adjustment select a suitable
thrust washer from 11A and reassemble the
components as described above.
Note: 11A = kit 823/10420 - comprises 6 thrust washers of
the following thicknesses:
4.3 mm (0.169 in)
4.4 mm (0.173 in)
4.5 mm (0.177 in)
4.6 mm (0.181 in)
4.7 mm (0.185 in)
4.8 mm (0.189 in)
5 Recheck the end float and then dismantle the
components. Assemble the clutch as detailed on the
next page. Be sure to fit the correct thrust washer 11 on
final assembly.
