HYPOID BEVEL DRIVE
Lift off differential assembly complete with crown
wheel and bearings. Remove crown wheel and
bearings taking care that outer races of bearings are
not interchanged, one side with the other.
The crown wheel is secured to the differential box
by eight setscrews (25), which are each locked in
position by a tabwasher (26).
Knock out taper pin (23), securing cross pin (22),
in differential box.
Push out cross pin; differential pinions complete
with thrust washers (21), can then be carried round
and brought out through the wide openings in
differential box.
On no account should an attempt be made to
remove the differential pinions from the differential
box without first removing the crown wheel. Due
to recessing of the differential box within the
crown wheel, removal of the cross-pin Is obstructed
by the teeth of the crown wheel.
Differential wheels, and· thrust washers (20), can
now be taken out of differential box through the
same openings.
Reverse the above procedure for reassembly of the
differential gears.
When refitting the crown wheel to the differential
box the following points must be carefully observed.
I. The faces of both crown wheel and differential
box should be thoroughly clean, and free
from burrs or bruises otherwise there is every
possibility of misalignment after reassembly.
Using a dial indicator check run out which
should not exceed ·003 in.
2. The tabwashers for the eight setscrews should
be renewed and screws tightened to 45-55 lb. ft.
3. Bearing cap nuts tightened to 50-55 lb. ft.
If bearings or crown wheel and pinion are renewed,
refer to the Instructions laid out In
the
following
paragraphs.
NOTE:-Should it be found necessary to renew the
bearings which carry the differential assembly, the
old inner races may be withdrawn by means of the
VLC tool RG4221 B and adaptors RG4221 B-20. Inner
and outer portions of these bearings must be
renewed as a pair, as is the case with all bearings of
this type. It is not permissible to renew either inner
or outer portion separately in any circumstances.
BEVEL PINION-To dismantle, adjust, and
reassemble (See Figs. I, 3, 5 and 6)
To dismantle
Remove the differential unit from the axle.
Remove the differential assembly complete with
crown wheel and bearings, as previously described.
Remove the self-locking nut (34), and washer (33),
securing the propeller shaft coupling. For this
purpose the flange holding wrench VLC tool RG.48
will be required.
Draw the coupling (32) off the pinion shaft.
Tap the bevel pinion rearwards out of the housing
Use. a soft metal drift to prevent damage to threads.
The inner bearing race and the shims at A and
B (Fig. 6) will be detached with the pinion, and
should be removed.
To remove the inner bearing race from the
pinion an arbor press or the VLC Hand-press
RG.4221 B will be required. Support the race
by means of the adaptors RG.4221 B-21 and
apply pressure to the threaded end of the shaft.
Remove the shims, but do not discard them.
Remove the oil seal from the front of the housing.
