Ringing Noise 2012 RMK PRO 800

RatchetRider530 · Mar 21, 2013

Up until today i have had no complaints or problems with my RMK. But about 1 hour in to our day i started hearing a ringing sound between 4500-5300 RPMs and didnt like the sound of it so headed back and only got worse as i rode back and the ringing would be between 4200-6000 RPMs by the time i got back. Shes only about 600 miles young?

Any suggestions on what could be causing this?

chasing something similar on my 13 pro. Sounds like a washer spinning on a loose bolt, been there for a while now mostly at cruising speeds at moderate throttle position. I'll be working on it tomorrow and will look for the source.

Ringing Noise

I have the same noise, so far I've put silicone on exhaust can springs, removed heat shield from battery. I have electric start, next I'm going to try the pull starter rope, it vibrates bad a low RPM, could be in the pull starter dogs.

If someone finds it keep us posted.

I would say mine is surely from the clutch side, will report back tomorrow night

Shims behind the secondary?

WingNutRacing · Mar 21, 2013

Interesting ...

I have noticed the noise also, its definitely from the clutch side. Seems to be something loose somewhere, but I can't find it... Sled runs fantastic and the noise doesn't seem to effect the performance at all.. I'm gonna have my dealer check it over... It could be the secondary shims dancing in there, never heard it on any other sleds??

Maybe the big washer between the sheaves in the sec.?

I had this happen there is a nut that came loose on your clutch you can look at your primary and see it rattling loose in there.

me too, a metallic rattling/ringing noise, from under the hood, only when moving worsens with increased rpms. any other ideas? brake calipers?

m1kflyingtiger · Mar 22, 2013

Are these all quick drive sleds?

sled_guy · Mar 22, 2013

Check the jam nut on the primary spider. I've had them come off and rattle back and forth on the shaft and make a funny "ringing" noise.

I bet you anything guys that the top bolt on the quick drive is coming loose and your break caliper is making the noise, this will also cause that bearing to spin on the jack shaft... mine is loaded on the truck right now on the way to dealer to get new shaft installed, there is suposed to be a update torque spec to 40-45 lbs on that top bolt on the QD, Good luck :face-icon-small-hap

Nope, jam nut is tight. Everything on the primary is solid.

Not on mine, My pulleys are tight. I have switched to a different bolt/washer/torque spec. All is well in my QD system now

Danbot · Mar 22, 2013

The washer between the secondary sheaves is my top suspect so far, I wonder if there's anything that can be done to silence it...? I'm just heading into the shop to work on the old girl.

Alright you guys are possibly going to think I'm Wacky here, but I have been trying to find this rattle/tinging noise for a while now. Been driving me crazy. 2012 800 Pro RMK. I finally found it last weekend!! Believe it or not, check into this. Ready, here it is. The parking brake lock is loose on the pin and rattling on the master cylinder. Easy way to test: When you start to hear the noise keep the speed and throttle you are at and put your hand on the brake lock and walla, noise gone. Mine was that simple, but caused me so much aggrivation. Let me know if this helps anyone.:face-icon-small-coo

sledheadd · Mar 22, 2013

Thanks leftys I will check mine as it started doing this on my last ride.

Danbot · Mar 22, 2013

Thanks lefty I'll experiment with that too.

I just finished working on my 13, and loaded her up for this weekend's trip.
-drive clutch is solid, and clean
-driven clutch is solid and clean but I can see how that washer between the sheaves could rattle in there.
-QD system is solid, no pulley or brake rotor wobble. Pulley bolts and washers indexed and still torqued properly
-Jackshaft and driveshaft bearings have no play, seem very smooth
-looked around everywhere under the hood, could find nothing loose or rattly except the starter gear is just a little sloppy

more testing / inspection needed I guess
