Re: IML: timing chain play



You should move the crankshaft with a wrench because the harmonic balancer could be slipping. If you still have that much play, yes, that is too much delay in the movement of the rotor. The 440 has plastic coated timing gears to increase silence. If it has worn off, or the timing chain has stretched, there will be too much play. Think about the distance the rotor travels to get to the next firing contact inside the distributor cap. To much play and the igntion timing cannot be set based on the timing marks.

Greetings all, 
 
I am trying to determine if there is excess slack in my timing chain on my 67 440. I have turned the harmonic balancer back and forth while watching the rotor and get about 3/4" of free movement at the balancer. Is this considered too much? 
 
Thx,
