Crankshaft diamiter at crank gear

Post  powerstrokeace on April 27th 2014, 11:16 pm

So I'm wonder what the demension is of the crankshaft where the crank gear is. I'm trying to degree the cam but can even get the damn gear on. I'm coming up with 1.384-1.385. And the gear is 1.381ish?

Nope this crankshaft was fat all the way around. I have 3 gears and they all fit a stock crank I have here in the garage. I may be pulling this thing out tonight and back to the grinders

How are they going to hone a 9 position gear? Would it no catch ?

If the snout is larger than it's suppoed to be, why not just hone the snout to the proper size?

I think machining the snout is what he means when he says, "back to the grinders".

Yep. I got it in a trade deal and don't have anything in it for the most part. I will never recommend one to any one....
So is it possible to have a multiple position crank gear honed out?

This can be adjusted with a bit of of polishing. You don't even need a big crankshaft grinding house to do it, it can even be done on a lathe with some emery cloth.

This is no different from, say, fitting a new piston ring into a bore, determining the end gap is too tight, and deciding it needs to be filed.

I had the exact same issue with a new Lunati crank a couple of months ago.
