I ordered a cloyes double roller timing chain and after I got the stock crank gear off I measured the difference between them and the cloyes gear is about 1/10"? thicker than the stock gear.

Will this be ok or should I take it to a machine shop and have it turned down a little bit?

That measurement might not be right, I did it a couple days ago but I'll go out and check it again to be sure.

 

Will not the crankshaft pulley be out of aline if he does not turn down the sprocket?

 

I actually went out today and the back of the cloyes gear is inset so it doesn't put the pulley out of alignment, I didn't notice that before when I measured it.

I can't measure it since my caliper won't fit inside of the hole, but I think it will be ok, but if not I'll find out when I get the car running.

Anyone else have any experience with this? Does it space the pulley out at all? Let me know if you can

 

I understand from what I have read that going to a double roller requires slight clearancing of the timing cover. Might search that. I doubt if turning the sprocket would help unless that is the widest part, but I think the chain is wider.

 

Yeah I know about clearencing the cover, but I thought that I would have to have the crank hub turned down a few thousands to keep the belt in line, but it looks like it will be ok.

I haven't gotten around to the cover yet, but I will as soon as my motor comes back from the machine shop and I start the reassembly. I'll take some pics of what I had to do since I haven't found any pics of it yet.
