CAMSHAFT CHAIN
Camshaft
chain
and chain guide wear
cause
the chain
to develop
slack,
wh ich will cause noise and may
resul
t
in
engine damage. To keep
the chain
from making
noise,
periodic adju stment is
necessary
in
accordance
with
the
Periodic Maintenance Chart (Pg.
1
O}.
However, if the adjustment
fails
to
keep
the chain
from making noise, the camshaft chain or chain guides
have
probably
worn past their
service
limits and will
need
to
be
replaced.

Continue
turning

then
stop.
NOTE:
Do not

the crankshaft backwards
(clock-

VALVE CLEARANCE
Valve and valve seat wear decreases
the
valve clearance,
upsetting the valve
timing.
If
the
valve clearance is left
unadjusted,
the wear will eventually cause the valves to
remain
partly open; which lowers
performance, burns
the
valves and valve
seats,
and may cause serious
engine
damage.
The valve clearance for each
valve shou
ld be checked
and adjusted,
in
accordance with
the
Periodic Mainte-
nance Chart (Pg.
1
O) and any
time that
the clearance
may
have
been
affected by disassembly
.
Be careful to adjust within
the
specified clearance.
Adjusting
to
a
larger
value will disturb valve timing and
cause engine
noise.
