MXU / 2018 MXU 450i LE Transmission question
« on: July 12, 2020, 12:37:14 PM »
There are supposed to be rollers on those pins. Looks like they have fallen out and gone missing? I think you can order them from kymco. Secondary clutch rollers i believe. The parts are listed under the “drive pulley” section
 Look up airdam clutches on you tube. He shows how to clock that secondary spring. That might give you an idea of putting it all back together. By the way its the same motor and clutch as the Arctic Cat 450

Now I realized you said you swapped the secondary’s so that might be fine. It’s gotta have something to do with the primary or behind it. Did you install the belt with the arrow facing foreword? Any damage in the primary ramps where the rollers reside or the fixed plate ramps? Maybe there is an issue with the bushing in the center of the primary that rides on the shaft? Loose or wollard out. What are the rpms compared to the other machine at the same speed?

Just thinking here... you say it gets really hot and the belt tears up. So I’m guessing the belt is slipping. Is there a glaze on the pulleys from the previous belts. When you replaced the rollers in the secondary did you disassemble and clean clean everything so no belt debris lodged in it?  Is the belt box totally dry( no oily residue)?  Have you thought about clocking the secondary to the next position to give it a bit more squeeze( less slippage).

Does it idle for long periods? Very little airflow through the belt box at idle. When riding slower trails do you keep it in low?  Running slow in high can cause heat to build up and burn through belts.  Have you tried posting on arctichat?

If anything i would check all the fluids and make sure all nuts and bolts are tight. You never know. Sometimes things get forgot. An accident is called an accident for a reason.

Yep probably rod bearings. That would require a new crank with rod
