Primary clutch exploded

[Crossfire12]

Apex 4 cyclinder, winder cyclinder different harmonics, is the apex clutch heavier in weight?

 

[ROCKERDAN]

Apex 4cyl with gear reducing PTO shaft had no harmonics causing issues like these triples, and I believe the Winder is exacerbated due to lightened crank. Adding weight to stub shaft stops much of this(Hurricane), and also a TEAM does similarly being 2lb heavier.

Only one clutch is out there mated to this 998 engine currently, and doing much better on belts, rollers, reliability.

The teams are blowing apart too. The steel spider expands at a different rate with the heat and cracks the aluminum around it. They are also harder to service, with less service parts available, not as tunable, and consistently slower than the yamaha clutches.

True story

Met one guy in Quebec in 2017 that only put 40kms on his thundercat before the clutch let go
They recalled all 2017 clutches

I heard it from a guy who told a guy who told his wife who told someone How many people had it happened to them because now not everybody on here has a Yamaha turbo, there are CATS I know you people don’t like cat parts BUT we all have turbos trying to help one another, Face it these clutches YAMAHA suck , Oh team is not made by AC.

Haven't been any reports of the new broken replacement Teams since 2017 and the new replacement ones been rolled out fast. At least Cat/Team recalled/replaced the early version right quick at no cost. Hows that working for the Yamaha Winder primaries that have since been exploding in a sudden epidemic? At least it sounds like it's an epidemic of late.

One thing is certain, the life expectancy of rollers and parts in a Yamaha Winder primary is not long. This 998 Winder hammers clutches worse than anything I've ever seen and the worst engineered clutch for it is the one it comes with from Yamaha. The replacement Team sure looks to be far superior for life expectancy & quiet operation as well as wider ratio from start to finish with its 1.5" belt.

Also, you can't go buy a Yamaha SideWinder clutch complete and ready to bolt on, have to purchase it in pieces and pay a premium, but you can buy a Team complete right from Cat at a reasonable cost.

The clutches don't just break all of a sudden, it can usually be caught if you inspect the clutches regularly!

See how the washer on the lower side of the roller is wore, that didn't just happen, the weight or roller had allowed for a incorrect swing for sometime previously.

damn it!

 

[Srxspec]

View attachment 144477 This is my stock nytro with a clutch kit in it. The spider broke tossing out the roller. This shows the extra webbing. I was running 8800 rpms when it came apart. The weight broke the movable sheave but did not tear out the mount.

You also have to remember that a Nytro flyweight is 20 or so grams lighter than what is being used in a Sidewinder.

I beg to differ with you , the yxrc is closer to a master piece than the worst engineered clutch . It first came out in 1993 on the exciter sx & has gone through minor changes until now . How many complete changes have the other manufacturers had in the last 25 years ? It was first designed for 90 hp sleds now we are putting 270 or more hp to them . Then u add guys like the original posters that has no rollers left in the clutch and blame a bad design lol . No clutch will last if you don't have parts in them .... yes maybe Yamaha needs to redesign to handle 300hp ,then we will be good for another 25 years

I went from Team clutches to Yamaha on my 2018 9000 High Country. First because of parts and springs selection that I actually have, and the fact that I am pretty sure I will always own a Yamaha, so I dont need another whole bunch of differents parts.
Secondly, My ''rapid reaction'' team clutch had really bad response. Primary slider were so tights that you can barely slide the moveable by hand sheave when there is no spring in the clutch. Clutchs offset were aligned by 2 Arctic Cat tuner and they were supposed to be in specs. All parts in good condition. You would not be able to keep your hand on the sheave after trail riding. RPMs were right on with my Dalton weights. Blown 2x factory belts and at 200$cdn each, I like better to blow a 125$cdn Yamaha belt. As for belt quality, for sure the Cat belt is a better belt. Because it is way thicker and longer, it can store a lot more heat before exploding. Thats is why some people claim that Cat are not exploding belts. You have to keep this in mind.
I have now 500km with the Yamaha clutches. Hard riding and testing. First they were really cold with the stock weights. Switched to Daltons and temps were going higher than I wanted. Did some adjustements and they are now in the good range, as my Viper was. But with more tweaking they should come as cold as I want. Aligned with Hurricane tool, it look like belt durability won't be an issue.
The response is definately better than with the Team.
At 700$cdn for both clutches and 21/41 gears and chain (from 22/48), it was an easy choice for me. I admit that they look to wear parts faster, but in my opinion they are faster and more efficient.

I'm talking about clutches designed/engineered and installed on the 998. The Winder clutch and the Team. We don't care about 25 years ago on a lame Exciter or even 5 years ago. I have no desire to put on another ratteling bucket of bolts from any other Yamaha either. Nor do I want an aftermarket billet clutch for a trail Sled. If I did, I'd run the tried and true Quigley Stage-Six six arm clutch I have sitting here on my bench, but the quick change splined spider is not good for a three cylinder four-stroke with its poor harmonics.

The Winder clutch is far from a masterpiece! So far, I've been replacing rollers at 600 miles when worn, and now the reports of all these things starting to blow. Granted, people don't bother looking at them like I do, but replacing rollers that cost over $120-$150 a set, and the ratteling harmonics tearing it apart, well thats far from a masterpiece IMO. Thats a piece of #*$&@ clutch! All the Cats got new clutches, and thats what these Winders need, a clutch that does not rattle, wear out prematurely and blow apart like they are doing.

Even when the cheap PB80 breaks, its only the spring cup, everything else stays intact. Vibrates like a SOB and you can shut it off with the clutch still intact. Pieces don't go flying everywhere risking life and limb with these whimpy things they call belt guards.

BOTTOM LINE, YAMAHA NEEDS A TOTAL RECALL AND A MORE STOUGT AND QUIET CLUTCH DESIGN FOR THE WINDER! NOW!

To me in this picture it looks like the spider is not lined up properly. Could be why the roller bushing is worn.
