Method

1.
Fitting the differential ossembly
(a)
Place the differential, fitted with beorings, in the end of the gearbox
casting.
(b)
Secure the differential in place using the two clamps MR630-64/16,
tightening the nuts by hand only.
(c)
Place new paper gaskets on the left
-
hand and right
-
hand drive shaft
assemblies, together with any shims removed
dvring dismantling.
Locate the drive shafts in the planet wheel and align the screw holes.
Fit screws, taking care to fit the correct len
g
ths and tighten.
2.
Adjust the pre-load
an
the bearings.
NOTE:
The bearings must be fitted with a specific pre
-
load. This can be
checked by
measitring the torque required to tom the differential.
(a)
To measure the torque fix and
wikd a length of cord around the
differential satellite
hhosing. Attach to the free end of thk'card to
a spring balance so the satellite housing can be rotated when the
spring balance
is
pulled.
(b)
Take a reading from the balance when the satellite housing
is
just
about to rotate.
This
reading should be within the following limits
given for bearings which have previousl
y
been used and new bearings.
(i)
Bearings previously used should be within
4
to
6
kg.
If
the
reading
is
less than
4
kg, increase the thickness of the adjusting
washers. For readings in excess of
6
kg reduce the thickness of
the adjusting washers.
(ii)
New bearings should be within
6
to
9
kg.
If
the reading
is
less
than
6
kg,
increase the thickness of the adjusting washers. For
readings in
excess of
9
kg
reduce the thickness of the adiusting
washers.
NOTE:
An adjusting washer
0.10
mm thick corresponds approximatel
y
to a
bearing stress of:
0.250
kg for new bearings
0.500 kg for used bearings
