IMPORTANT
NOTE
- Do
not
turn
the
crankshaft
after
it has
been
fitted.
The
valves
are
not
under
control
and
if
one
of them
is
raised,
the
piston
of
the
corresponding
cylinder
would
not
be
able
to
pass
the
T.D.
C.
without
fouling
the
valve.

To
adjust
the
end
float
of
the
crankshaft
(see
Pl.

Fit
a bearing
thrust
ring
(6)
with
the
groove
engaged
on
the
retaining
pin,
an
adjusting
shim
(7)
0.05
mm
thick,
the
thrust
washer
(5),
the
crankshaft
pinion
(temporarily
without
the
key),
tighten
the

Push
the
crankshaft
towards
the
bearing
on
the
timing
side
by
means
of
a lever
or
a wedge
placed

the
crankcase.
b)
Measure
the
clearance
between
the
bearing
cheek
(6)
and
the
thrust
washer
(5)
(at
"j").
This
clearance
must
be
between
0.03
and
0.09
mm.
Choose
from
among
the
shims
sold
by
our
Spare
Parts
Department,
those
which
give
this
clearance.
