REAR AXLE
18.
Install the pinion head bearing on the dummy pinion
(tool M84B-l) and assemble it in the hypoid casing.
19.
Fit the pinion tail shaft bearing, centralizing collar,
flange, plain washer and slotted nut.
20.
Tighten the slotted nut until a torque of IS to 18 Ibf
in (0'17 to 0·21 kgf m) will just turn the pinion.
21.
Set the pinion gauge (tool 84B) to zero.
22.
Install the gauge and the dummy bearings in the
hypoid casing.
23.
Maintaining slight pressure on the gauge body, rock
the stylus across the dummy pinion, observe the
gauge readings. The minimum valve is recorded when
the stylus is parallel to the axis of the dummy pinion.
This valve is the thickness of the shim(s) to be fitted
between the pinion and the pinion head bearing.
24.
Remove the gauge and the dummy pinion from the
hypoid casing.
25.
Fit the four bolts holding the mounting flange to the
hypoid case IS to 20 Ibf in (2'1 to 2·8 kgf m).
26.
Fit the required shim(s) to the pinion shaft and fit
the pinion head bearing.
27.
Install the pinion in the hypoid casing.
28.
Fit the bearing spacer, tail shaft bearing drive flange,
plain washer and castellated nut.
NOTE: Ensure that the tapered face of the bearing spacer is
fitted adjacent to the tailshaft bearing.
29.
Carefully tighten the castellated nut checking the
pinion bearing pre-load. Shim the bearing spacer as is
necessary to obtain a pinion torque of 15 to 18 Ibf in
(0·17 to 0'21 kgf m) when the castellated nut is tight
to a torque loading of 90 to 120 Ibf in (12'4 to 16'6
kgfm).
30.
Remove drive flange.
31.
Press the oil seal into the hypoid casing (lip towards
the pinion).
32.
Refit drive flange and nut to a loading of 90 to 120
Ibfin (12'4 to 16·6 kgfm).
33.
Fit the locking wire to the castellated nut.
