1 of those recurring BRP Issues RTL Front Srocket

[askitee]

Just an fyi that my 2017 RTL had its front sprocket replaced about 18 months ago under warranty. A check last week has found the replacement is now doing the same - producing the red dust, luckily my '17 RTL is still under warranty.

This is precisely the sort of thing BRP need a kick in the nuts for.

By "doing the same thing" you mean it's loose on the shaft splines again?

BRP failure.

The front sprocket very recently FAILED on a friends F-3:cus:. On top of that she was truly hosed by the only dealer in town for over $600 to do an hour or less work. BRP really has dropped the ball on this one.

Thanks Peggy/Howard, have updated my post to describe the issue better - doing too many things at once

From the description, it sounds as though they neglected to lube up the splines before assembly. Fie on them.

BRP has been covering these even on bikes past the warranty date. Usually only for original owners though as a goodwill gesture.

Is there a brp recommended maintenance procedure to prevent the sprocket failure?

I initiated my own procedure and so should anyone who knows which end of the wrench to hold.
Keep a front pulley bolt on hand and periodically (you determine what that is) R&R the front pulley, clean both splines, apply a thin layer of moly paste - not moly lube.
With but 5K on my F3L, I did that and found that BRP had applied a very small amount of a white grease
that didn't appear to be moly paste, which is dark.
Even though this is covered by warranty, I don't want my Spyder parked in some dealer's shop while awaiting the arrival of parts. Then having some Wrench Ape screw it up.

How do you hold the sprocket to keep it from turning while removing/replacing the bolt? I recall seeing the paste listed in another thread; will look that up and get a tube. My F3 is coming up on 5k shortly so this will be a good project for the winter.

Keeping the tensioned belt installed with parking brake on, loosen the bolt.
Remove tension on belt.......remove pulley.
Reverse procedure for install....torque bolt when enough belt tension will hold pulley. Properly tension and align belt per shop manual.

Per the above, but add; After the bolt is removed, raise the rear wheel off the floor and while rotating the wheel, walk the belt off of the rear sprocket. Reverse to install the belt.

Removed my sprocket today. No red powder or dust visible before removing. Very little paste on the splines. There was slight rust on both surfaces however no signs of fretting or looseness. This is at 16000km. Caught just in time I think. I ordered Loctite 51048 to reassemble.
