Front Sprocket Failure

I have been doing a search for part numbers and I can find no superseding part num for the original:

Are my sources out of date?[/TD]

I guess. I had to order the part since the dealer wouldn't until they verified the issue and they got BRP to agree it was warranty. agreed to reimburse me for the cost if it was bad and covered. The parts department confirmed the change in part number.

Trust you gut folks, sometimes you get a feeling that something is not quite right. Take a second to check it out. Jumping around on either RT or F3s or F3t left me questioning if I could feel something or it was imagination. Yesterday the splines on the front sprocket had finally worn enough that it spun on the shaft. Less than 9,000 miles. Not happy but the timing could have been worse, much worse. Had I been trying to pass on a two lane road or make a left turn across traffic when it failed I would have been left hanging. It is something worth keeping an eye on. Take a small flashlight and peek behind the cover that is in front of the rear sprocket. There is a small pan underneath that filing will collect on. Additionally since the shavings have become "charged" they stick to other metal parts and will even stand up in the tray. A one minute check could give you an idea if you have a problem or need a closer examination. The failure also explained why my belt kept creeping and needing adjustment.
Now the waiting game. No dealer appointments until a week from tomorrow and they won't order parts until they see it and verify with BRP that it is warranty. Wonder if this is a part or build issue. This was the first F3s delivered in FL. I only have 9k on it and I know others have more. Curious.

hey, did you by chance have the belt readjustment to address the vibration?

The belt was adjusted twice because it wouldn't track straight. It would move to the inside of the rear sprocket after about 1k miles. Obvious now that the front sprocket was going and as the play in the sprocket increased the belt would move. I don't think that belt tension is what caused the problem with the sprocket but I do think it is a factor in when it happens. I the highest mileage I know of personally was around 26K on a 2016. Others sweem to fall in the 12k to 17k range and mine at 9k. What I don't know is if more tension makes it last longer or kills it sooner. You could make an argument for either way. A looser belt would have more flutter which could shake the pulley more causing an early failure or a tighter belt would apply more loading to the splines and shifting (loading and unloading) could cause an earlier failure. In either case my sprocket is toast I a sit (not so patiently) waiting for an appointment at the dealer so they can examine, talk to BRP to see if it is warranty, then order parts. If I was in a cooler climate and had a limited ryding period I would probably be screaming a bit but thankfully here in FL we get to ryde year round. To short circuit the process some I ordered the sprocket and it should arrive just i time for my appointment next Friday.

The F3 and RT both use the same part# for the front sprocket. The RT's are using a substantially higher belt tension, are they having the same failure rates with the splines wallowing out?

Haven't heard about RT problems. The F3 now has a new part number for the front sprocket. Guessing some kind of change? Tighter material spec? Of bigger curiosity is how belt tension played into the equation. As I stated above I could see it either way. In any case I see belt tensioners in our future for both bikes.

Front Sprocket Failure #2

Had my 2nd one go in just over 10,000 miles, this time while in Yellowstone. Major expenditure to get the trike back home, as dealer closest to there (Rexburg, ID) was willing to "look at it" but not yet dealt with this specific issue.

This is my third Can-AM (had the GS and RT) and never had this issue before - so something is clearly wrong. And just to be clear, I am NOT one of those guys that likes to paint the blacktop with burnout stripes.

Not a lot of faith with the product or the company at this time...

Wow. so sorry to hear this. I do think the vibration issue and the new BRP tensioner are related to this. The RT with the same front pulley is not having this issue .

I have my 9K+ maintenance services at the end of the month. I am going to have them check the front sprocket since I myself cant seem to see where it is exactly.

The front sprocket is pretty easy to find, just follow the belt forward. The bolt in the center of it is accessed by removing a small plastic cover on an F3. Just forward of the frame side casting with the passenger peg bolted to it.

 

[monkeyboymorton]

As the RTs aren't having this issue could this be related to the different rear sprocket size on the US spec F3?

I'm just going to go and check mine now as I'm on 10K miles, but of course I have the US RT spec rear sprocket on my euro F3.

I bet a good machine shop could make one out of billet aluminum.

front sprocket

I've stripped 3 front sprockets on my 08 Spyder , Brp made the center of the front gear softer ; so it strips out before transferring the energy inside the crankcase to the transmission gears :sour: !!!

I jump my Spyder @ RR crossings ; thus the need for replacing it 3 times It jumps great stays nice and flat thru the air !!!

the newer design sprocket has an inner and outer flange to help keep the belt on track ( the first series had only the outer flange which allowed the belt to " walk " on the front sprocket

That didn't Mel's monster garage made a 30 tooth aluminum one back in 08 and aluminum is way to soft if the steel ones are failing why go with a softer medal?

 

[Sam Mac]

I was under the impression that they were cast Aluminum. To be honest I have never seen one so I guessed aluminum.

I wonder how long it will be before you bust the frame. opcorn:opcorn:

Home Again!

My baby is fixed and back home again! The gearbox fear was just that, fear. The Central Florida PowerSports did order one and had it on hand just in case but after examination and testing all that was needed was the sprocket.

2009 spyder belt tentioner

The F3 and RT both use the same part# for the front sprocket. The RT's are using a substantially higher belt tension, are they having the same failure rates with the splines wallowing out?

Could you give us a discount on 2 tensioner now that the f3s are less than 2009 rs and they have stopped making them as of this year . Hope to hear from you bigal55.

 

[KID Ryker]

Thanks

The failure is the bolt coming loose. Its not the pulley that is the problem. Once the bolt is loose, either the pulley or the shaft is going to fail, the pulley is the easy to replace part so designed to fail first.

Check the bolt torque on that pulley every oil change.

:agree:Thanks good ideal. Checked 3 - f3. 2 f3s with 5000 miles 1 was loose. 1 f3t 400 mile was good. Will do as you said. Check the bolt torque on that pulley every oil change. Great ideal :thumbup:

 

[Tazzel]

Finally found the front sprocket area, mine is clean as a whistle. I have my 9300 maintenance scheduled for the end of the month, I will have them double check the sprocket condition.

Is this happening to mostly 2015 models?
