Sprocket Final Fix Update from Shawn Smoak

[Freddy]

LOCTITE® 609 is a green, high strength methacrylate ester acrylic retaining compound designed for the bonding of cylindrical fitting parts. The product cures in the absence of air between close fitting metal surfaces. Typical applications include rotor to shafts in fractional and subfractional horsepower motors. Locks bushings and sleeves in housings on shafts. Augments press fits..

LOCTITE® 660 is designed for the bonding of cylindrical fitting parts, particularly where bond gaps occur without the need for remachining. The product cures when confined in the absence of air between close-fitting metal surfaces and prevents loosening and leakage due to shock and vibration. LOCTITE 660 exhibits excellent gap cure characteristics and is also suitable for retaining shims. .

I wonder what BRP actually says to use?

Ugh, wish they get the new sprockets out soon. I'm #4 on the waiting list since the 1st of Sept. Went to the dealer a couple weeks ago, still no word when they'll receive the first sprockets. They said they would do the quick fix though I want the finally fix so they do have to do it a second time.

I'm keeping my fingers crossed, my dealer just called and scheduled us in for Dec 23 for the sprocket recall.

Maybe we will get a nice Christmas present.

We've been using Locktite 648 for years with very good results. This was recommended to me by one of BRP's head Spyder techs. Just a guess but I would say we've done close to a hundred or more repairs with zero failures. I've done this on all 5 of my Spyders with no issues to date. I'm still not understanding the washer thing but I'm sure they went this route for a good reason. I'm sure the key to fixing this is going to be the Locktite. It has worked well for me and my customers.

I did this to mine also.

LOCTITE® 648 is a green, fluorescent, low viscosity, high strength, urethane methacrylate acrylic, anaerobic retaining compound designed for bonding cylindrical fitting parts. It prevents loosening and leakage from shock and vibration. Typical applications include holding gears and sprockets onto gearbox shafts and rotors on electric motor shafts. It provides robust curing performance.

I haven't seen parts in-my-hand, but the washer appears to fill the ditch/groove at the end of the splines on the transmission output shaft, and would be assumed to be consumable, just like the sprocket (vs the shaft). I would test the hardness on the washer: it is probably less than the sprocket hardness and much softer than the shaft. Its purpose likely two-fold: in the event of a future sprocket failure, it would prevent the sprocket from getting locked onto the transmission output shaft by the remaining ring of splines (currently providing much anxiety and effort when trying to extricate the sprocket from the shaft) and provide a bit of compliance as everything gets locked together with the Loctite (like the seal washer on a drain plug). r.e. hardness: if there is no relative movement between the sprocket splines and the shaft splines, thanks to the Loctite 648, the hardness of the washer would be relatively minor. To me, it looks like a sound, engineered solution.

Recalls don't expire. Once all units have the fix, NHTSA will close the recall.

And, I did notice that this sprocket is made in the USA, and I'd be willing to bet that it is a third party vendor. So my question is, what is the supply chain issue and/or the material shortage issue (which BRP claims there is) here? A company here in the US can't get the material to make these sprockets? Are they made from some mystery material that they can only get from Russia? The part is not coming from overseas, and I would think that whatever company is making them HERE would be cranking them out in pretty substantial numbers. I also wonder why BRP is claiming that the cyberattack on their systems is slowing this down as well. Seems to me that there's a lot of smoke and mirrors here.

BRP is a Canadian company (Valcourt, Quebec) so if the part is made in the USA, it is still a "foreign" item from BRP's viewpoint.

I agree it's frustrating to wait for so long, but the rest of your statement is speculation.

 

[Cobwebs]

No answer to my message to Shawn Smoak regarding the washer or metallurgy unfortunately. Was informed by a third party that he doesn't answer questions:hun:. I'll try BRP direct but don't hold out much hope of getting any trade secrets out of them either .Failing that I'll come up with a really crackpot theory and spread it far and wide over the interwebs:roflblack::shemademe_smilie:

Maybe the reason for the washer is as simple as stopping excess loctite from getting anywhere near the shaft seal.

I wonder you guys that used 6** loctite ,how hard is gonna be to remove if you ever have too. I work with it all time in industrial jobs and really hate it when time to disassembly,it takes a lot of heat, probably drill 2 holes and thread it.

Fingers crossed that I never have to remove it, but if I do...challenge accepted.

I don’t really care how hard it is to remove, mandytuning, because my dealer will be replacing the old sprocket, and if the new one malfunctions, the dealer will be replacing it, as well

I had the issue in October, 2022. I broke down going to work. They did a temporary repair. I then received an additional email from brp Dec14, 2022. Called dealer in Surprise, Az. Haven’t heard a word since. I don’t blame the dealer but i regret buying this thing. I am leery to drive it.
