Hi All, my problem all started when I installed the HOCA Race variator, I installed a new one and I still having the issue. I am going to try ditching it and just ordered the NCY Teflon coated Variator
This are the parts i replaced bout a week ago.
so far I have:
* Hoca race Variator with 12 grams rollers
* NCY 1500 RPM Contra springs
* NCY Gen 3 Clutch with red springs
* Snow flake clutch bell
* NCY aluminum drive face
* NCY Secondary driver
* Gates Premium belt 743 20 30
I was thinking about getting perhaps the blue contra spring but the belt broke even before that change.
Also my belt is a very very tight fit. is that Normal and could that be contributing to the belt breaking?
My buddys belt is not as tight.
Thank you - Luigi

Perhaps you are putting the wrong sized belt on

Well worth the extra price. The only problem is how to find one that's not a counterfeit. "Gates Premium" is just a standard Gates belt, and most likely a counterfeit since it seems most sellers are (knowingly or unknowingly) selling Chinese knockoffs ... Gates name and everything, but still knockoffs and low quality. There was a long discussion on this a few months back. Best bet - order online from Walmart for pickup at the store. Best price and pretty much assured to not get a knockoff. |

Iv'e found this to be a good source of high quality parts, the only trouble is they ship from Europe a it takes forever (like a month or more) to get here.  www.racingplanetusa.com/ |

Obviously the belt locked up.
Had that happen once with a new variator. I was using a different inner face whose ramp angles allowed the rollers to go too high (up AND OUT of the variator).
I'd first suspect the rear end and make sure it all rotates freely. If the bearings locked it would explain the belt failure. See also if you can detect any reason within the clutch assbly that might have led to a lock up condition. The heavy rubber deposits on the drive face indicate tghe belt suddenly went stationary while the driveshaft (and attached variator/drive face) continued to rotate.

I have used the Hoca with a real Gates belt with no problems. Something is either misaligned or binding so you need to get to figure that out before throwing more money into a new variator. I used the matching drive face for the Hoca that Parts for Scooters sells and did not mismatch parts from multiple sources.
Beware that some vendors with bargain Gate belts are selling fakes and not the real thing so that is something that you have to watch out for and again why I deal with Parts for Scooters to ensure I don't get counterfeit parts and always get great support..

Hoca is Very good quality. Like my fellow "Dawgs" I thinkin' locked up bearings. I had a spacer rub against a spring loaded clip, form a "tin-can edge" and pop a bearing seal.  |

Hi All, I am not sure where the bearing is located. However i think you guys may have nailed the issue if the variator seems like it is locking up. I am not sure how the variator works for sure, but one thing I did notice about the hoca race variator is that the boss would not fit around the shaft and the variator back part it self would fit but was very very tight and I would have to wigle it quit a bit to get it to push all the way back on the shaft. I ended up using the stock boss which look identical to me to the hoca one. Now if the variator is supposed freely roll ontop of the boss then yes the variator can be very much locking up as it is probly locking up against the shaft it self.
I will have to take some pictures of the stock variator vs the hoca variator and post some pictures with hopefully some noticeable differences.
BTW i did get my belts from partforscooters dot com
Thank you

The bolts to access the bearings are behind the clutch.

Man that looks like a lot of work. I can see the bearing causing the clutch to lock but not the variator. I will try my luck with the new variator first. I also just change my gears recently and everything seemed find from what I could tell. thank you

The variator would continue to spin with the crankshaft ---- but if the back end locks up the belt will either continue to turn with the variator, and be torn up by the locked up rear end, or the belt would freeze with the back end and be torn up by the spinning variator. In your case, with all that rubber on the variator drive face, it kind of looks like the belt froze and was eaten up by the turning variator. |

I had the belt brake on me already 3 times in like 3k miles. The last time it broke I replaced everything but the variator, see first post, including clutch. only thing I did not replace was the variator. First belt broke after installing variator. I am not sure if it is the variator and perhaps it is just a coincidence, but my belt broke after installing the variator and I replaced everything since but the variator so I will give that a try.
