throw a 5/8 deep socket on the crank bolt... with a breaker bar...

rock the harmonic damper back and forth..

if you feel more than 5/8 of an inch of movement as measured at the surface of the damper.. the chain and gears need to be changed...


5/8 is a lot of slack..  but when the nylon teeth fall off.. there can be way over 5/8 of an inch...

i normally find 3/8 to 5/8" on many motors..
