Refitting
(11) Place the differential assembly in the transmission,
slightly towards the
flywheel.

Refit the housing with its joint washers and tighten
the nuts firmly yet not too tight, to allow the
assembly being displaced when the right-hand end
cover is fitted.
(13)
Refit the right-hand end cover with its washer.
Tighten the screws evenly; as they are tightened
the differential assembly
will
be pushed slightly
away from the
flywheel.

Fit the left-hand end cover without its washer and
tighten the screws just enough
to
nip the bearing

and the housing in several places and tighten or
loosen the screws to even the gap at all positions
. where measurements are taken.
