No, That wasn’t me. I didn’t see sparks either. But what mine was doing by mid day 1st ride, I was having belt squeal at idle and start up if it was shut off. It would squeal for about 5 seconds then stop.Man, that’s crazy. I saw one post where the guy saw sparks come from under the roller bearing. Was that you?
I sort of think the center bearing has something to do with the failures. Its real easy coming from previous sleds and just dealing with a little belt squeal. Usually it will stop after a few miles, maybe its set that way on purpose, maybe the belt is heated up. But if there’s squeal on these with the bearing, it needs attention. For example.....I could grab the bearing by hand and spin it until it would bind. Once it stopped or bound up, I could not move it. I would say when the bearing seizes, strange things could/likely will happen. Could be that they aren’t getting attention until its too late. Mine also had some odd burning and wear on the belt(30 miles). Just speculating with all of this.Why is it that the 18+ explode but the nearly identical 16/17 do not?
The significant difference is the larger center hole for the bearing.
That alone is not the cause... but may be the base for the cause? Or could it just be poor manufacturing?
I noticed that the part numbers have changed from 18/19 to the 20/21 modelsAll of our clutches have the same aproxmiles. Wondering if the slider bushings on the spider are the issue? Grab the inner sheve and outer cover , lots of play. Garbage clutch , plus can’t rebuild. Cat isn’t Gona keep up with the competition at this point and I hope they’re watching this Forum.
