CHRYSLER SERVICE MANUAL
ENGINE—21
(see
Fig. 29),
"Camshaft Installation".
Use
straight edge
to
check alignment
of
timing
marks (Fig. 27.)
Slide fuel pump eccentric over camshaft
against sprocket (Fig. 28). Be sure slot
in
ec-
centric lines
up
with protruding camshaft
sprocket key. Install cup washer and bolt and
tighten 35 foot-pounds torque.
b.
Checking Timing Chain for Stretch
Place
a
scale next
to
timing chain
so
that any
movement
of
chain may
be
measured. Place
a
torque wrench and socket over camshaft gear
attaching bolt and apply torque
in
direction
of
crankshaft rotation
to
take up slack;
30
foot-
pounds torque (with cylinder heads installed)
and
15
foot-pounds torque (heads removed).
Holding scale with dimensional reading even
with edge
of a
chain link, apply torque
in
re-
verse direction
25
foot-pounds (with cylinder
heads installed)
and 15
foot-pounds (heads
removed), and note the amount
of
chain rota-
tion (Fig. 29). Install new timing chain,
if its
movement
is
greater than %
6
inch.
NOTE:
With
a
torque applied to camshaft gear
bolt, the crankshaft should not move.
If
there
is
any
movement, however,
the
crankshaft
should
be
blocked
to
prevent rotation.
If chain
is
satisfactory, slide crankshaft
oil
slinger over shaft and up against gear (flange
away from gear.)
