Refitting
(6) Check the primary gear running clearance (Fig.
A.16).
Fit
the inner
thrust
washer with its cham-
fered bore against
the
crankshaft flange.
(7) Renew the crankshaft primary gear oil seal
if
it
shows signs
of
damage
or
oil leakage, using Service
tool
180

This seal
can
also be renewed without removing
the housing
or
draining the engine/transmission

the recom-
mended torque.
It
is important
to
return
the

to
the positions from which they were re-
moved.
Later engines were fitted with non-lubricated bushes
,in
the
primary gear.
No
oil feed is provided from
the

and
no
oil seal is fitted in the flywheel.
(10) Remove the primary
gear
as described in Section
A.18.

When
refitting, check
the
running clearance (Fig.
A.I7).
(12) Adjust by fitting the
