Hey folks, I tried a Cloyes standard timing set but I think there's a little too much slack in the chain because of the line hone on the mains.
I've been looking but can't find anything undersized except for Mopar and Chevy. Anyone know where I can get a .005 undersized set?

 

I'll bet if you bought a better set it would be fine. I use and sell the Cloyes 9-3513-9x and have never had an issue. And ALL my builds get align honed. Just a suggestion.

 

I don't want to hijack this thread but the 67 chassis service manual shows the timing marks with the cam mark at the 6:00 position, not 12:00 like this picture. How does it really go? Also is that really too much slack?

 

I'm a little confused on this point. Do I understand that some Cloyes come with a non-Coyes chain?
How much for your set and how soon can you get it in the mail. There's just not much else I can do until I get this resolved.

Ed(?), I'm pretty sure this is correct; cam gear @ 12 and crank @ 12 on compression (assuming rotor is pointing at #1 plug wire). But now I'll have to double check.
Isn't Chebby 6 & 12?

 

What really verified that it's too loose for me was turning the crank with a wrench so I could get that sticky, red, Permatex assembly lube on all the chain and sprockets and, while turning, the chain would stick to the gear for a bit and then pop back out with a snapping sound (sticky assembly lube). Difficult to explain but yeah, it's not extremely loose but enough to make me uncomfortable. I think it has about 3/8 inch movement from left to right.

 

Did I say I didn't have anything else to do until I get the chain issue fixed? I've been vacuuming and mopping and cleaning the house all morning. Save me!
Although I did get the dishwasher fixed. I'd forgotten what it's like to not have to wash dishes by hand

 

That's funny, Mac! My wife has a list of Honey-Do's just waiting for the times that I'm stuck waiting on parts for my project.

 

Hi mac, may have the .005" under set on the shelf (5.039"), will let you know next week!

Thanks, Gary in N.Y.

P.S. I probably won't be at the shop until around this coming Wednesday!

 

Lol! That's one of the reasons I try and carefully time my purchases!

Hey Gary, I just bought another, higher quality Cloyes from cutlassefi. He seems to think the trouble is this cast sprocket set. HOWEVER, hold on to that .005 for me. I'll know if this new set will do the trick by later next week. What's the manufacturer and price for your undersized set? PM me if you'd rather not say in this thread.
Thanks buddy!

 

My Street roller Cloyes timing set was similar new and more slack than that once ran about 10,000 to 20,000 km. Looked loose but only 1 degree or so on the timing tab. That Cloyes billet set looks super nice. There are chain options, I assume that one has the super high quality German roller chain. You marks are 180 degrees out FYI.

 

Not sure what you mean here. 12 o'clock and 12 o'clock is #1 compression.

I have a circle center finding jig and a digital caliper but aren't we talking thousandths of an inch? And is the stock distance available somewhere? I don't see it in the CSM. And BTW, my '71 CSM has the cam and crank timing marks pictured wrong.

 

The cam and crank timing marks should be directly above and below each other with the balancer on 0 or TDC for #1.

 

I had to go to a -10" chain just a couple of years ago due to how the shop did the align hone on my 403. I also had to wrestle with bearing alignment, thrust alignment, etc etc.

Yikes! Cloyes used to make -10 and -5 Olds chains in the true roller, e.g. 9-3113-10. Looks like there's some old stock floating around and the fancy top of the line stuff is still available.

Don't bother trying to measure center to center at home. You need a proper jig to do it.

 

Hi mac, that set I thought I still had in stock sold a while ago, the number is also discontinued but I can get a different number and it will be .005" under. It is a higher-end "Tru-roller" though.

If you still need help contact me with an e-mail, I get them daily! Theengineshop@aol.com

Thanks, Gary in N.Y.

P.S. The cost is going to be in the neighborhood of $200.00 by the time you receive it with all the freight, this includes the freight in to me and out to you? This is NOT a normally stocking number for us so I have no choice on shipping!

 

Whether the cam gear is at the 6 o'clock or the 12 o'clock position doesn't matter as long as the one you use is TDC for your engine and has the valves closed for the #1 cylinder. In other words if setting it at 6 o'clock has the lobes up and opening the valves you'll have to rotate it 180* and get the lobes down so the cam is on the base circle.
Aftermarket manufacturers don't always follow factory guidelines.

 

Mac,


Have you resolved this issue? If not let me know.

 

he did say he turned the crank.if he turns it another turn the marks will line up.

 

Thanks Gary. I haven't received the new set yet but I'll let you know if I need to go under.

Trip! How ya' doing buddy? I'm planning on spending tomorrow evening doing just that. I'll drop a couple lifters in the #1 and have a look. I didn't realize manufacturers might do that. Thanks for the heads-up.

 

Doing well Mac, thx for asking.

I went through the same situation with my timing set but once you realize that the cam rotates at twice crank speed it all makes sense as stated by others here and elsewhere.

 

Mark, I can't find this part number anywhere..?

 

Here are the first 3 that popped up in search

So, here's the deal; if you're looking for undersized, you have to call summit, ask for that part # Cloyes timing set and specify .005 or .010 undersized. They don't have them on their website.

The set I got from Mark, the Cloyes billet, fit like a glove. Much tighter but not too tight. A quality piece for sure.

 

I copied and pasted. Whoops. The exact PN posted yielded no relevant results which prompted the question.

 

I'm very happy with the fitment.

 

It looks like it's one tooth off.

 

I don't think so, Mark, but I'll double check. I remember thinking the photo made it look that way.

 

That's just how Mac holds a camera.........

 

Lol! Oh Randy, you're always good for a laugh.

 

That is a very nice looking set, it will be going on my next build. That one is the regular roller chain, the German chain is $20 more. The timing marks are easier to tell right above and below at 12 and 6.

 

It's pretty, isn't it? Do I have to cover it up?!

Yes, I checked it at 12 and 6 and it's right on. It's just the wide angle lens most phone camera have, I guess.
