locate the drive shaft i n tCle planet wheel and align the screw holes.
Fit screws, taking care to f i t the correct lengths and tighten.
(e)
Place the gearbox carting on i t s left-hand side, supporting i t i n
this
position.
(f)
Place against the right-hand differential bearing the adjusting washer
(1 3)
followed by the distance washer (1 2) and the distance piece (1
1 )
.
The total thickness
(12)
and (1

should not be less than
9
mm.
(g)
Locate the right-hand differential drive shaft i n the planet wheel and
align the screw holes. Without a gasket fitted on housing,
fit
the
assembly i n position and tap lightly on the differential shaft.
(h)
Remove the right-hand drive shaft, adjusting washers and distance
piece.
2. Adjust the pre-load on the differential bearings.
NOTE:
The bearings must be fitted with a specified pre-load,
(a) Place gauge support TOOOT0614, fitted with dial gauge TOOOTO615, on the
collar of the right-hand drive shaft housing. Allow the probe of the
gauge to touch the bearing faceof the housing. Bring the zero of the
movable dial o f the gauge i n line with the large needle. Note the
position of the needle.
Example: Large needle reading
=
0
Small needle reading =
0
(b)
Place the d i a l gauge and support on the gearbox castingwith the probe
bearing on the distance piece. Take two measurements,
Example: Measurement A
=
7.76mm
Measurement
B
=
7.80mm
Average A and
B
= 7.76+7.80
=
7.78 mm

(c)
Add to the average measurements the following items:

Stress on the bearing
=
0.30 mm
Total =
0.40

. . Select an adjusting washer and a distance washer with a total thickness
nearest to the calculatedthickness.
