The distance between the outer edge of the casing
and
the bearing outer race must be measured and,
if
re-
quired, adjusted to the correct dimension by
means
of
spacers.
A
distance from
0.3
to
0.3
mm to the cover plate must
remain. Thc thickness of the original packing
(0.5
mm)
must bc takcn into account. Find out whether the
spacel- bush

has been damaged by the sealing
lip
and check that thc scaling ring is in perfect working
condition.

The clutch shaft must be free to move easily; if this
is not the case. use a rawhide mallet to drive the shaft
(lower

0.2
mm
and then use
a
