Came loose... what would cause that, and what can it hurt? I have used reverse a lot lately?
Primary nut that looks like a crown?
- Thread starter PowderMiner
- Start date
How big is it?..the only nut I can think of is th espider nut..and it needs to be there and be tight...run it by a dealer and have them retorque it....

It is the one on the shaft inside the primary spring, has half circles around the edge. It came loose this weekend and is going "ring-a-ling" on the shaft. I'd take pics, but it is on the trailer getting snowed on!
The sled is really ripping, it is getting me places like into tight steep powdery creek draws that i'd never of tried before!
Gives me a good excuse to get it in the shop, the front walkers are feeling soft, hope to just get them pumped up, don't want to buy new shocks this season.
Just hoping there is no damage because of it... the back country is just heating up!

2000 miles... We (I watched) just changed springs & stuff, thought everything was done great, but stuff happens.
Had a weird vibration a week ago, (Long story, but nothing noticeable happened to cause flat spot or any defect; and none were visible) changed belts (115's not new, but broke-in ~800) on the hill no fix still vibrated, got home put new belt on vibration gone.
Maybe the 15 miles of bumpy trail while vibrating loosened it then the next hard ride it backed off?
It might not be good to ride with a bad belt, and apparently I only get 800 miles out of my 115's?
Guess I'll pick-up a new belt too and put the one with 200 miles in the spare holder?
~800+~800 old belts, 1 defective belt delaminated bad bond (warrantee) at 190 and new belt ~200

Did the guy break down the spider when he did this work (to replace the sheave bushing or clean up the shaft)? Not to knock his skills or abilities, but if he forgot to torque down that assembly (or didn't torque it enough), I would wonder if he got it back together in register (although you'd think that someone who has the special tools needed to break down the spider assembly would know how to do it right).
It has to be taken apart to be torqued anyway, make sure the X's are in register when it goes back together. Lucky the spider itself didn't come loose or something might have broken.

Very same thing happened on my son's '09 Shift here in the flatlands. One year old, 2000 miles, he heard the ringing and found the crown nut wandering up and down the clutch shaft. The dealer tore it down, added another dose of loctite and performed the strong arm torque. It appears to be happening on many different Polaris sleds, so its a clutch thing I would assume goes back to initial manufacturing. Properly done, that nut should never back off on its own.
Thanks for these posts guys... something for us all to watch for and be aware of in the future. These Polaris clutches are so easy to get into & work on compared to other machines but ofcourse there are always the small things like this that throw a wrench in the wheel... Thanks, Chad

I am almost certain that the clutch was put together correctly with proper torques, inspection, cleaning, and alignment. That is the main concern, as I might need to have a little extra torque, lock tight, and not use reverse as much, or not to ride for prolonged periods with vibrating belt.?
Thanks a bunch for the replies and I’ll post with the shop findings later this week.

Mine did the exact same thing this weekend...15 minutes riding, tore the track (again...I will not port one this time...) and put it on the trailer and rode back up sled. When we loaded up to leave started up the dragon with the bad track and heard the ringing and noticed it was loose. Happened once before and had the dealer put it together. That was probably 500 or more miles ago..will tear it down this week.
My sled is on its way to the shop for the second time in three rides with this same issue. Funny thing is, if I would look at my clutches more often, I would be noticing that nut is always loose. I have always heard the ring-d-ding, but could not chase it down. I've notice some vibration too. I will have the shop look at the crank to see if it is causing the nut to back out and will post what I learn later...
If the spider turned under load that nut will become loose....It won't hurt anything but the clutch may not be as balanced
If the guy putting the clutch together does it right this nut does NOT come off.
The Polaris clutch actually tightens itself (sheave tightens if lose) when engaged in forward gear.
That said, if torqued right, it doesn't tighten.
And what's more, a little blue loctite on that nut when assembling and it won't come lose.

Makes me wonder if someone is not torquing the spider itself enough before torquing the nut down. If the spider itself wasn't torqued down enough before torquing the nut, when the spider self-tightens as you described, the nut would then be loose.
