Hi,
Just installed a new UA485 Ultimax belt on my Zforce 1000, and in begining it was fine, driving like new but the after driving at 40km/h I started to hear some sounds like little whining, and smoke was coming out of the cvt exhaust, still driving fine thought.  I stopped right away and towed it back home to not ruin anything more.

The question is it normal and it's just breaking in? Or I have done something wrong, and installed it wrongly.
I will take it apart again tomorrow just incase and take a look.

Another thing, previous belt feel apart when I was driving at like 60-70km/h.

Thank you for your time, any help would be appreciated.

[is it normal and it's just breaking in?]

 is it normal and it's just breaking in?

No.

It sounds like the engine is going faster than the secondary, and the belt isn't locking in.

Wondering if the belt has the wrong bevel angle for the drivetrain. Were you driving slowly up hills in high gear? Carrying a lot of weight? Get the belt wet? etc ....


At any rate, you'll find out as soon as you remove the belt.

As I understand UA 485 suppose to fit my zforce 1000 according to their website.
I just replaced the belt with new one and drove it for like 5 minutes. There was just 1 little uphill and then I noticed smoke and little "whining", stopped and towed it back home.

Either way it isn't normal and the fact that it did smoke the belt says its gone now and will have to be replaced. Better check on how you assembled the primary during installation as well as the direction...and condition of the oneway sprag/idler bearing. 

Solved the problem. While my previous belt exploded it somehow sucked allot of belt parts into my snorkel, even thought I checked the ends and thought I cleaned it. What happened was when I was driving for those five minutes, some belt parts fell down and started to rub on the new belt creating smoke and noise. I took it apart and cleaned both CVT and snorkel, and now its running like new.

I continue to be surprised at the remedies I see in hear :-)

Glad it worked out!
