About 3 months ago I began hearing a rattle coming from the engine/transmission area. The rattle was only noticeable while decelerating. So last week noticing it was getting louder I took it to my local Can Am dealer. They determined the front sprocket bolt had come lose. Background info: This is a 2019 RT Limited I purchased new in August 2019 and I began hearing the rattle with about 10,000 miles on it and now has about 18,000 miles. The tech contacted Can Am to see if it was acceptable to re-torque the bolt using red thread-lock and Can Am agreed. When I picked it up that morning the rattle was gone but after about 50 miles the rattle returned and was worse than ever. I immediately returned to the dealership and they discovered the bolt was loose again and I could see where the sprocket had damage on both ends of the splines. They have ordered a new sprocket and bolt. The splines on the transmission shaft appear to be in perfect condition.

There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

Common problem which surprisingly the dealer tech wasn’t aware of..........make sure he applies moly assembly paste as listed in shop manual.....very important step! There is a TSB which addesses this issue.

very sloppy dealership to only "think" its the bolt problem and NOT the pulley. how could they be right there, and see the splines were worn and not REPLACE it. time to find another dealer after this!!!!

Yes, this is CanAm’s big issue, Woodaddict. Every manufacturer’s vehicles come with some kind of issue, which is usually addressed by mechanics at your dealer. However, too many CanAm dealers cut corners, and put their junior 2 wheel mechanic on Spyder maintenance and repair, resulting in someone who knows virtually nothing about Spyders, and only limited knowledge of 2 wheels, working on your Spyder.
Sure CanAm have dropped the ball too, as evidenced by poorly designed front sprocket assemblies continuing to be rolled out, but EVERY tech working on a Spyder should be made aware of common issues like sprocket failure indicators if they are tasked to work on Spyders.
If you have a good dealer, but they are a fair distance away, enjoy the ride there. I do not use my local dealer:thumbup:

I’m obviously not the OP, fatboy, but just as an aside, I let the Spyder change down 95% of the time and have not experienced sprocket issues (I probably shouldn’t have said that :lecturef_smilie: ). Do you think manual down shift increases or decreases the possibility of sprocket failure?

IMHO the really BIG problem is the Tech at that dealership :gaah:, as others have posted, the Front sprocket is a well known issue on the newer Spyders. Good luck getting this fixed the way it should have been done when you made your complaint about it ..... Mike :thumbup:PS Can Am / BRP NEVER told them to use RED LockTite..... so somebody is lying :banghead:

If it did, then surely this would've been a far more prevalent problem in the SM machines.... only that doesn't appear to be the case?!? :dontknow: And I've been pretty much exclusively shifting my SE down manually (sometimes even 'aggressively'
) since the day I bought it - back in 2013.... and I've never had any issues with the front pulley &/or bolt either?! 
opcorn:down shifting when riding aggressively is not the problem because when riding like that you usually are back on the gas when down shifting to use the engine as a brake you are applying an opposite force on the sprocket and bolt that it was designed for there for loosening bolt or wearing teeth on sprocket
That certainly sounds reasonable, but since BRB isn't giving out any information why the sprocket/pulley bolts loosen, it's pure speculation. It could be that the bolt
wears on the sprocket/pulley and loosens due to that rather than the bolt physically turning and loosening.
What I was trying to say is that if the sprocket/pulley rotates a bit when, either accelerating or decelerating, which could be due to wear
of the sprocket/pulley splines, that movement could cause wear on the area of the sprocket/pulley under the head of the bolt, thus allowing
the bolt to not hold the sprocket/pulley as tightly as it should. Not due to the bolt physically loosening, but because the bolt no long clamps
the sprocket/pulley as tightly as it did before the sprocket/pulley wore under the bolt head.
As I said your answer is reasonable, but only if they actually gave a real reason behind the sprocket/pulley loosening. And if the sprocket/pulley
doesn't physically rotate then it isn't going to loosen due to the action of deceleration/acceleration on the bolt.
