chains to be visible through the two lower openings
on the idler sprocket (4 o’clock and 8 o’clock).
Once the secondary timing chains are installed,
position special tool 8515 (6) to hold chains in
place for installation.

engine oil.
10. Install all chains, crankshaft sprocket, and idler
sprocket as an assembly. After guiding both sec-
ondary chains through the block and cylinder
head openings, affix chains with a elastic strap or
the equivalent, This will maintain tension on
chains to aid in installation.
