Testing Timing Chain for Stretch
(1)
Place a scale next to the timing chain so that
any movement of the chain may be measured.
(2)
Place a torque wrench and socket over the cam-
shaft sprocket attaching bolt and apply torque in the
direction of crankshaft rotation to take up the slack;
30 foot-pounds torque (with cylinder head installed)
or 15 foot-pounds torque (cylinder heads removed).
(3) Holding a scale with dimensional reading even
with the edge of a chain link, apply torque in the re-
verse direction 30 foot-pounds (with cylinder heads
installed) or 15 foot-pounds (cylinder heads removed),
and note the amount of chain movement, as shown
i n Figure
88.

gines.
NOTE: With a torque applied to the camshaft
sprocket bolt, the crankshaft should not
be
per-
mitted to move. It may be necessary to block the
crankshaft to prevent rotation.
(5)
If the chain is satisfactory, slide the crankshaft
oil slinger over the shaft and up against the sprocket
(flange away from sprocket).

Removal
(1) Position the puller screw of Tool C-3506
