TIMING CHAIN
CAUTION: IT IS ESSENTIAL that the installation pro-
cedure is followed exactly. Failure to do so will
result in severe engine damage.
CAUTION: Cover timing case recesses to prevent
foreign material from entering engine.
(1) Connect new timing chain and old timing chain
with the assembly link, the assembly plate and the
assembly locking element, and secure (Fig. 56).
NOTE: Always keep new timing chain meshed with
camshaft sprocket.
NOTE: Rotate engine at crankshaft only. DO NOT
crank engine and DO NOT rotate engine backward
(Fig. 56).
NOTE: Draw out the end of old timing chain evenly
as it becomes free, to the same extent that new tim-
ing chain is drawn in (Fig. 56).
(2) Draw in new timing chain by rotating the
crankshaft slowly in direction of rotation of engine
until the ends of the new timing chain meet and can
be connected (Fig. 56).
NOTE: Assembly link is only an assembly aid and
NOT designed for engine running.
(3) Remove assembly locking element, assembly
outer plate and assembly link (Fig. 57).
(4) Attach new timing chain to camshaft sprocket
with tie straps..
(5) Insert new riveted link and new middle plate
into ends of timing chain (Fig. 58).
(6) Take off retaining devise at cylinder head.
(7) Remove camshaft sprocket from camshaft with
timing chain secured.
