2016 low speed belt chatter

[CB.8]

My diamond drive when it was going out sounded more normal then boss secondary at low speeds. At least it made it 4000 miles before it went. The boss secondary didn't make it 4 miles before it started to go.

So this "normal" scraping is causing this scar to go deeper every ride. I'd say I have about 20 more rides till the reflection bolt wears through the steel plate.

That cannot be good. Is that from the deflection adjustment bolt?

Yes. I don't know why they did not go with a Tied type setup. The Tied secondary has opposing deflection adjusters that have pockets that they rest in on the inside. If you want to see what is happening, remove your clutch and pull the helix and spring out and manipulate it with your hands. You will see that the deflection adjuster hits first and then it gets cocked to one side until the belt travels down far enough to act as a stabilizing force between the sheaves.

Yeah, that's from 100 miles! By mid season my secondary will be toast!

 

[summ8rmk]

I hope there is a change in the design soon.

For what it's worth, Those marks are from the sheave rotating Backwards into the reverse notch in the cam.

I have the same marks on my secondary. Have 125 miles on mine. My marks aren't as long as yours but it is digging in the same way.

No it's not.

The deflection bolt needs a derlin/plastic tip to slide on the steel plate.

Sounds like an option. Can that damaged steel plate be replaced easily? What is your dealer saying?

 

[northof40]

140 miles on this one. Noise started at 10 ish miles.

Doesn't look like it can be replaced. Dealer is Cutler's/CPC Racing. Dale is looking to Arctic Cat for an answer.

 

[Chewy22]

I didn't think that plate could be replaced. Going to be spendy replacing everyone's secondaries. Hard to believe this wasn't noticed/caught during testing or with all the 16 demos being rode last spring...............

 

[DDECKER]

Cat doesn't have enough guys out testing there products,

 

[Brutus]

Or maybe the product changed some between testing and rollout? Helixes are different in some cases... Anything else??? Wyo has logged some good miles, let's see what his looks like. I would expect worse if these sleds have 150 miles on em compared to Wyo's. at any rate prob gonna be a warranty recall down the road for Ac.

Front Range Cats 16 spring demo looks way worse. Prob 400-500 miles on it

 

[kiliki]

anybody try putting in a second deflection stud and nut in the hole you use to spread the chiv open? this would help stabilize it at low speeds and reduce the about of pressure by half on the inner part. just have to mark the one your using for deflection and just take the slack out on the other. if you blow a belt just use a 4mm and take it out to put the spreader tool in. definitely not a fix but might buy some time.

 

[CB.8]

Yep. Didn't help.

 

[Insaneboltrounder/sjohns]

team tied has two.

My limited sounds like metal is grinding in the primary until about 5 MPH. I'm sure not getting a blow off valve type noise. Plan on pulling the clutch and having a good look tonight.

Same with mine
