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. 11 to 13)
Suitable jigs as illustrated are available from Messrs.
V. L. Churchill & Co. Ltd., Tool No. RG.328
(H.329C). When adjustment is necessary it can
be carried out by the use of these jigs, which are
shown in operation In Figs. 12 and 13.

Remove the differential assembly complete with
crown wheel and bearings as previously described.
Remove split pin, nut and washer and withdraw
propeller shaft driver coupling. On some cars a self
locking coupling nut Is used and
no split pin �tted.

For this purpose the flange-holding wrench VLC.
tool RG.48 will be required. Tap out the bevel
pinion, using a soft metal drift to avoid damaging
the threads. The Inner race of the rear bearing,
distance washer A, shims B and C and bearing
spacer, which have become detached with the
pinion shaft, should be removed. (Fig. 11).
The inner race of the bevel pinion bearing should

Section G (Rear Axle)
be removed from the pinion by means of an arbor
press using a suitably shaped drift block to support
the inner race, or using the VLC Hand-press RG.
4221-B with the adaptor RG.4221-6. Pressure should
be applied to the threaded end of the shaft. A
thread protector must be used.
Inner and outer races of bevel pinion bearings
must not be renewed separately as these are mated
in manufacture. Failure of a bearing necessitates
renewal of the complete bearing assembly, com
prising inner race, rollers and cage and outer race.
Remove the oil seal from the nose of housing, as
preload is checked without the seal.
Now take the dummy pinion shaft (see Fig. 12) and
place on it the inner half of the rear bearing, the
bearing spacer and any shims which were originally
fitted between this and the bearings.
Do not yet flt Shims or Washer between Inner
Bearing and Pinion Head.
Make sure that the bearing inner race is fully
"home" and that no foreign matter is present
between bearing, bearing spacer, and shims.
Fit the dummy pinion shaft, complete with both
bearings, spacer tube and the original shims; tit
the dummy coupling nut and washer and tighten
fully (see Fig. 12). If the shimming adjustment Is
correct the bearings should be preloaded, I.e., tight
enett beyond the normal position for free movement.
The extent of the preload is measured by testing
the torque required to turn the shaft; this should
be 5-9 lbs. Ins. (0·6-0·10 kg.m.) for new bearings.
When reassembling the bevel pinion with the
original bearings, the preload is slightly less; the
torque required to turn the shaft In this instance
is 3-7 lbs. ins. (0·04-0·08 kg.m.).
The torque loading can be checked conveniently
by means of an ordinary tension type spring balance
of suitable calibration. This should be attached
