Timing Chain Installation
1. Remove the rocker arm pins and rocker arms from
the cylinder head.
2. Install the Crankshaft Hand Crank Tool into the
nose of the crankshaft. Set the jam nut so the
crankshaft can be turned left or right.
3. Rotate the crankshaft until double--dot alignment
marks on each gear face each other. (The
engine will be set to BDC when the two sets of
double dots face each other.)
4. Install the the Timing Chain Installation Guide,
PN--PW--47079, into the two bedplate fastener
bores.
NOTE: The Timing Chain Installation Guide tool
will guide the chain around the crankcase bends
while preventing the chain from catching on the
balance shaft sprocket.
