Katech Timing Chain Slack
Was wondering how much slack is acceptable? Thought it would have been allot more difficult getting the timing chain on, but theres about 3/8" of slack in the chain.
Wondering if a new upper and lower gear set would help, or am I just being paranoid?

That's a lot of slack. I measured the slack on my JP Performance 5618T and the slack was about .310" when the parts were brand new. The Cloyes hex-adjust which replaced it has around .100" slack. I could do an actual measurement with calipers if you wanted. You could see pictures of the JP in the link below if you were interested.

Thats normal for an OEM chain from what I've seen. They make a damper you can install to help remove some slack as well. I believe running the chain that loose is what took out my motor eventually. I'd run a tighter set or a double roller.

I'll reinstall it and spin it a bit to see if it goes away, but im gonna go ahead and order a newer upper sprocket anyway and see if that helps. Or maybe try and get my hands on a Cloyes set.
I do have a dampener from my previous block, but i want the majority of the slack gone first.

Do it once, do it right! Cloyes hex a just gears with a Cloyes C5R extreme duty chain. use the damper if you have it as well.
Dual chains may look tight when new, run them 20/30k & see how slack they are.
I broke a dual Rollmaster & the dual inmotion chain that got taken off just recently & replaced with the Cloyes was sloppy also.

I talked to Katech about that Cloyes combo. they are not the prestigious C5R chains that Katech sells. They are some other chain maybe still an IWIS but not what comes from Katech as the C5R chain.

If you asked about a C5R chain then possibly you will get the weaker thinner option.
Contact TSP or Summit which is where I got mine....

My thoughts were always, a double has to be better than a single, but not now with the extreme duty C5R.

I spoke with Katech themselves. This was more for an fyi, so people do not think they are getting the same Katech C5R chain. . When you say C5R chain it is more widely known as the one from Katech. Feel free to call them and get the same response.

I emailed Cloyes about trying to get a set of gears only from them but wasnt able to because their kits are hand matched. Both the Katech and Cloyes top of the line chain, the "Z" chain are both made by IWIS. Though maybe not the same exact chain, they are supposedly equals. The "Z" chain is noted with a Z in Cloyes part numbers
Going to go ahead and get a Cloyes set and be done with it.

Just me, but when I did my ls2 chain I got it from the sale thread Yank had. I opted for new billet gears from them as well. It also came with a Torrington bearing (which was a nice surprise)
I didn't have hardly any slack in mine at all. As a matter of fact, I played hell getting the cam gear on bc the chain was a bit tight and had to be just "perfectly" lined up to slide the gear on.

I measured the slack on my Cloyes 9-3153 hex adjust set yesterday because I was curious. The slack was .117" from slack to tight with the calipers in roughly the same position as the pictures shown in the thread I linked above.
