Front sprocket assembly paste

[TIMMB]

BRP did use assembly paste on the front sprocket at least in 2020.

I can see where it wouldn’t hurt to have this inspection as routine maintenance

Assembly paste? Looks like lithium grease to me. If so, big fan of the blue stuff ... works well on shaft drives as well - pretty much anywhere you have a splined gear.

I checked the splines on my 2017 F3L bought new in Feb.'19 at 4K miles and the grease looked like white lithium to me. So I cleaned it off and applied Moly Paste.

When I had first inspection and oil change on my 2020 F3, had them check out the front sprocket since it has been a problem in past years, but only has 3000 miles on Spyder! All good, but will continue to check it each service.

What would be wrong with Loctiting the front pulley to the splined shaft with 638 Cylindrical Bond?

Actually, many have done this.
Let me explain downsides though. The prep must be absolutely correct. The Loctite application must be uniform. The assembler must allow 24 hours or more cure time for Loctite.

FWIW, while others were Loctiting, and this goes back now many years, I was likely the first to use Moly paste on the splines. I did not invent the idea, simply copied what we do on drive spines used in aircraft. Yes, I have decided upon an interval to reaccomplish the spline inspection and relube.

But yes, Loctite of the proper grade will work too.

I think it should be another thing to check and do when changing the oil!!

Not a bad idea, and may vary depending upon oil change intervals. I go each 5000 miles, so possibly every other oil change.

Then again, according to the other guy, if you never manually downshift, the pulley splines last forever...

I just checked my front sprocket on my 2020 RTL and it too had the white grease. It wasn't really assembly lube, it appeared to be the white lithium soap based grease.

Just for the record. I reapplied some Honda Moly 60 I have from a previous project. I inspected the retention bolt and found it to be a conventional hardened steel (10.9) bolt with the usual yellow BRP loctite. I cleaned the threads and reinstalled using blue loctite. Super easy once you get to it.
