2023 F3L SES Front Sprocket BUSTED! Has anyone else with a "newer" Spyder had a sprocket issue?

[PURPLE ON THREE]

Pretty much all you can do is look for the red dust. If you try to re-torque the bolt, you will break the bonds of the thread locker. I can’t recall cases of red dust still happening with the new sprockets. This looked more like a case of sudden, catastrophic failure. They get serviced at Hanover PA, and we know that they stay on top of things.

Snowbelt, on my 2018, Ryan at Hanover changed the previous sprockets when he spotted that "red dust of death"...one time I had only traveled another 8,000 miles and it was time to change it again...

Yeah, you've got an excellent support system there with Hanover. And it seems like the dealership where you are now is competent enough. Otherwise, they would have just slapped a new sprocket on there and sent you on your way. The 2018, of course, was part of that recall population. Those sprockets had a specific machining defect from the vendor, and for a while, replacement sprockets that were still in the supply system had the defect also. All that has been corrected. Your F3 came with the new, corrected sprocket. This failure has a root cause of course, just not the same one.

Just saw the picture. The sprocket and shaft did a pretty good job of grinding away on each other. Are you getting a new shaft also, or have they evaluated that already? Oh, just read your update in post 1.

Once you get it all buttoned up, I think that your biggest issue from then on will be traffic and sun screen. Off you go. Be safe.

Lol, traffic and sun screen! Well, it's going to be warm here in Florida this week so we already need the sunscreen, but I'm not complaining! I was happy to not have to ride in heated gear on Saturday to get down here! I understand what you're saying about the root cause... I just wonder what that may have been... maybe Lenny can share more once he replaces that output shaft... Have a blessed day!

What actually fails? The fit between the splines of the output shaft and the sprocket? Poor metal hardness of the sprocket? They require locktight to take up the slack? Is the output shaft damaged if the fit fails?

Well, I know the output shaft on my 2018 was fine, even though I had three sprockets replaced.

What we are finding out with the 2023 is poor metal hardness of the sprocket leading to poor fitness of the splines of the output shaft and the sprocket. With the poor metal hardness of the sprocket, sometimes just the sprocket fails, or in our case, there is damage to both the sprocket and the output shaft. The Loctite does not take up any "slack". It's just a safeguard I guess.

I want to see that output shaft... and I will, we saw the sprocket. I'll add photos of the output shaft once I get some pics of it. BRP wants the failed sprocket and output shaft back.

Altho admittedly, this one does sound very much like the previously encountered shaft issues, there's a chance that it might not be the sprockets actual mounting to the shaft bit that's at issue - we've seen a couple here where the guide flange on the edge/sides of the sprocket has broken off the sprocket proper - so the sprocket still functions and is properly connected to/mounted on the output shaft, but ring that was that flange can be trapped between the engine and the sprocket/belt, or if it's on the outside, come flying off as the sprocket spins, making a helluva noise as it does so, but in either case, the belt can (and does) then eventually wander off the sprocket during normal operation!

I think there's at least one pic of a sprocket that's failed like this posted here on the Forum, and there's a few more comments from owners over your way who've had the same experience; but IIRC, there have only been a few instances like this and they've all been fairly recently. I'll do a bit of a search around later, to see if I can bring anything up.

Thank you, Peter!
