this figure, it will be necessary to dismantle the hub
and brake disc to investigate the cause of the run-out.
3.
After checking the run-out, slacken the shrouded
nut, then, using a feeler gauge placed between the
outer bearing and
key
washer, to give between 0.002
in. (0,05 mm.) and 6.004 in. (0,lO mm.) bearing end
float, tighten the nut sufficiently to grip the feeler
gauge lightly.
Alternatively, use suitable dial test indicator equip-
ment secured to the stub axle to obtain the required
end float.
Continuous rotation of the hub is essential during
this operation to ensure that the taper rollers seat
correctly in the outer races.
4. Peen the shroud of the nut to locate in the grooves
of the stub axle; remove the feeler gauge or alternative
dial test equipment.
Note Incorrect setting, exerting a load on the
bearing or giving excess end float, will
promote premature bearing wear.
The remaining operations for fitting the rear hub
unit are a careful reversal of the procedure given for
its removal and dismantling, noting the following
points.
7.
Fit the key to the drive-shaft taper and torque
tighten the yoke retaining nut using the torque spanner
(RH
8014) and socket
(RH
8026).
Note Cars produced prior to car numbers
SRX
1916-Standard cars, and
CRX
1937-Coachbuilt cars, require the yoke
retaining nut to be tightened to between
450 lb. ft. and
475
lb. ft. (62,21 kgm. and
65,66 kgm.). Cars produced after the
above numbers require the yoke retaining
nut to be tightened to between
500
Ib. ft.
and
525
lb. ft. (69,40 kgm. and 72,58
kgm.).
The increased torque figure applies
only to the cars following the numbers
quoted and on no account should the
yoke retaining nuts on earlier cars
be
tightened to the increased torque figure.
8.
When connecting the half-shaft universal joint to
the hub unit yoke ensure that the joint seats correctly
in
the yoke and that the bearing cap setscrews are
torque tightened in position.
9.
When connecting the brake linkage and brake
feed pipes, refer to Chapter G-Hydraulics, for special
precautions to be taken.
