GEH and i were talking clutches and he asked about how the belt was riding in the clutch. So, it just so happened that I took a few pix of the belt yesterday morning:   (that one was with el cheapo installed (note the large "dead zone"), before putting the Dr pulley back on). So last night, returning home from church. Admittedly riding the poor thing hard - faster than it has gone before and really running like a little banshee .... then, all of a sudden "pop" and no power. Engine rev'ed but ... nothing. Knew immediately the belt had popped. Pushed the scooter the last mile or two (getting O L D !), then took a look first thing this morning. Powerlink was pretty new. But what a mess !  With strands stuck down in the clutch and variator:   This is my first belt pop, so I'm not sure what to make of it. Fortunately kept the old bando, so back running again till a new belt comes in. But is it normal that the shredded strands would be so twined down into the clutch? Should I think maybe I have a clutch problem going on? Or is this just par for the scooter course? |

Just a procedure question: are you sure you had the right size of belt? That belt pop looks not so bad, first time I got a belt pop was a COMPLETE MESS!! It was a random belt brand made mostly out of rubber, I had rubber dust all over the CVT, the belt was completely pulverized, I had to take apart everything to clean it off.  |

These variators get too hot. I have lost two belts and they shredded into mulch and stings. I read the break in procedure when I bought my next gates belt. No hard throttling or high speed runs for the first few miles. I don't remember how many, 10 or 30 miles or something like that. |

The only time I ever had a belt break on me was because of a clutch problem. With the clutch still on the scooter I tried to squeeze it open and it was very difficult to do that was my first clue that i had a clutch problem besides the belt breaking. if it is a clutch gone bad and you put a new belt on there it wont last long. also what kind of belt are you using and what is with the discoloration on the broken belt it looks black/white

Not saying it will work with anyone else's scooter. Just think, if you are going to deal with issues, get a bullet proof drive belt! lol |

You have been taking off and reinstalling the belt yes? Do you remember if you possibly put the belt on in the reverse direction from when it was first installed? If you ever put it in reverse it will unwind the thread inside the belt. Once you wear it one direction, always wear it that direction. It is concerning that your belt popped from what looked like brand new the day before. Even if it was running hot I would think it would wear fast and get loose before it just popped without any burn marks or anything. Looks unwound to me, but that's just me. |

Gates Powerlink The clutch IS too stiff to compress by hand - needed channellocks to do so and get the strands out from between the pulley halves. And .... have a 2K main spring supposedly on the way, so it will soon be stiffer. IF I put it in --- just found out on my motorcycle, after putting a new water pump, thermostat and radiator in, I have a head gasket to also replace (which means getting that head rebuilt also). Running out of motivation for projects .......... |

Might have run it backwards.
Took it off once maybe .... usually do NOT do so just to mess around with the variator; let it dangle from the clutch. But "might" have once - can't recall for sure.
Was actually wondering if the clutch opened too far & the belt went down between the pulley halves - and that's how the strands ended up stuck down there. But the clutch pulley looked OK this morning when I pulled it apart (except, of course, for the strands stuck down there.
Wanted to get a kevlar belt but my Puerto Rico supplier didn't have any for the 150. So, got 2 more Powerlink belts. Maybe get a Kevlar one somewhere else also ....

It is normal for strands to be everywhere when a belt fails, especially at high speeds, that's par for the course.

Looks unwound to me, but that's just me. interesting, i've never heard of this. is that for real? i have 2 old belts, one with 6,000km and another with 4,000km. i'm installing a new clutch this weekend and was planning to replace the belt with the old 4,000km one since my current belt has about 5,900km. i'm sorta hoping his belt shredded because his clutch needs a gorilla to open and not cause he put it on backwards. really didn't know that was even possible and sorry but a bit skeptical. guess i will know when my belt snaps.  |

Keep an eye on your CVT ! A broken belt , "especially if it is a gates with low miles " indicates a CVT issue . you have been having some unusual happenings with your CVT. With the need for very light variator weights , and a broken belt , this may be a bearing or clutch issue.
Can u take a pic of the belt where the writing is ? I'd like to see if it matches up with a true gates belt.

I had a belt snap before , but it was a cheap fake Kevlar that the guy I bought the scoot from gave me . it snapped in about 300 miles , and was in pieces.  . I lost some of it on the road since my CVT is opened up. |

I lost some of it on the road since my CVT is opened up. Here ya go. Pic of the last piece I have:  Wish you would pay your internet bill! Need more of you right now on this problem!!!!!  About the clutch. Of course, I have no idea what main spring is in there - have not yet mucked around with a clutch on these. But if I try to pry apart the pulley halves it's almost impossible. With channel locks they separate - and I (for the first time, actually) watched the clutch this morning as I rev'ed the engine and the pulleys DO separate. Seems smooth, though I have no idea if it's taking too much force. As I said - just squeezing the clutch with my hands does not really separate the pulleys at all. Wheel spins freely; the clutch turns easily and without apparent binding. Have a pair of Powerlinks coming from Puerto Rico (he didn't have any Kevlar belts of this size). Carrying the electric torque wrench under the seat till this is better understood ... though it would not do much good at the moment since the only belt I have is the used Bando (OEM) thats currently installed. Your photo looks even worse! But my belt was fine 12 hours earlier .... Nervous. |

I'm not sure if this matters but , all the gates power link belts I've ever bought had the POWERLINK in yellow . if I'm not mistaken even the non Kevlar powerlink was in yellow print. Like I said I'm not sure if that matters or not . where did you buy it from ? Also all of mine came with the paper gates sleeve also . the top pic is a Kevlar that is in the CVT right now and the bottom is a non Kevlar .  .  . |

Get this , I tried to get Verizon and they said their lines where full ?? I guess the lines here where I live are so old that they cannot take anymore customers or it will overload the lines , lol . I was going to go with the local cable company but they wanted 300 bills upfront and at the moment we are kinda low on $ so no internet for now . i have a galaxy mega 2 , so at least the screen isnt real small, lol |
