16
Fit the crankshaft outer thrust washers
with
the oil slots facing forward, followed by
the steel thrust washer
with
its countersunk
aperture facing rearwards.
17
Fit the Woodruff key sprocket spacer and
crankshaft sprocket.
18 Using the crankshaft pulley or flywheel,
turn the crankshaft until the Wood ·
uff
key is
pointing
to
'

o'clock'.
19
Turn the camshaft so that the groove in
the end
of
the camshaft is in alignment w
it
h
the Woodruff key on the crankshaft.
20
Replace the camshaft sprocket along
with
the timing chain and secure w ith
two
bolts
and the locking plate.
21
Using a straight edge, check the
camshaft sprocket is in alignment with the
crankshaft sprocket. The valve timing mark on
the camshaft sprocket should
now
be pointing
to
the Woodruff key
on
the crankshaft.
22
Check timing chain tensioner for wear,
renew
if
necessary, and locate on the lug in
the timing chain cover.
