Re: Timing Chain Play
From manual #17:
Checking Timing Chain Deflection
With timing chain and sprockets installed, check timing
chain deflection, as follows:
1. Rotate camshaft (in either direction) to place tension
on one side of the chain.
2. Establish a reference point on the block (on taut
side of chain) and measure from this point to the
chain.
3. Rotate camshaft in the opposite direction to
slacken the chain, then force chain out with fingers
and again measure the distance between
reference point and timing chain.
4. The deflection is the difference between these
two measurements. If the deflection exceeds 3/4
in. (19 mm), timing chain should be replaced.
