crank key/timing gear fitment

[Jason 302]

I have a FRPP steel timing set. The crank key only fills up about 1/3 of the groove in the lower timing sprocket. Width wise it fits well but it isn't very tall. The groove in the sprocket is just so much deeper than stock and the balancer, the key doesn't fully fill those either. Are there aftermarket crank keys out there that are taller than stock? I goin to my machinist tomorrow to see what he thinks (hardcore ford guy) and replace a ring my dad busted.

Even if it doesn't fill the entire groove up and down I don't see it being a problem as long as it fills it side to side. When you buy a new Harmonic Balancer they usually come with a new key, if that helps.

I wouldnt worry about it, as kenny said as long as it fills it side to side that is all that should be fine

Yea, I looked at it today, it should be fine. I guess it fills up more than 1/2 the groove, not 1/3 like I wrote before. My new balancer didn't come with one, I didn't know most of them did. My dad just doesn't like something when it's not how he thinks it should be. But i got everthing on now and the cam is degreed so it's behind me now. Thanks guys.

I got the same timing set and the key filled the sprocket full....
