Clutch engaging noise

[goforbroke]

Sled makes a loud noise when clutch engages. Any ideas why?

I think that’s belt noise. Check your belt deflection, it may be running a bit low in the secondary.
I’ve heard that when swapping a belt and the secondary hasn’t fully closed after removing the tool yet.

belt to sheave clearance??
deflection?
broken primary spring?

i'm sure some of the experts will chime in

Just changed primary spring. Changed to a gayes belt. Still same issue. Belt to sheave clearance was .025. sled runs awesome. Just loud engagement.

All stock components?

Something is funky with the secondary. Take a vid of the clutches engaging for a more accurate Snowest diagnostic session.

Gates take a bit to break in, my guess is that after a few miles the angles have met and now she is a bit loose...adjust a half turn out on the secondary!!

99% sure the belt is slipping in the secondary. Does it do it after the belt and clutches warm up a bit? If there is moisture on the belt it will make that sound when it slips in the secondary also. Have you had the secondary clutch apart? Does it shift out correctly after you are moving?

I would check deflection.

I will check deflection. It has do e it since new. 250 miles now. Just put in TRS clutch kit and changed weights, springs, helix. Noise is the same every time. I checked primary belt to sheave clearance. I haven't checked deflection. I'll do that next.

Take a look at the secondary. Is the belt right at the top? Adjust your deflection if the secondary is closing.

You commented it has done it since new. If deflection is good, disassemble the secondary and check that the components are all there.

I took secondary apart. Rollers look good. Spring and cup look good. Put in new spring. Still need to adjust deflection.

Getr done! This is something you should do before you go on your first ride, and every few rides after that. Takes 2 minutes.

I agree with what others have said, sounds like belt noise because of too much deflection. I actually had the same squawking going on yesterday, tightened my deflection to where it should be and the engagement noise went away.

 

[Jaynelson]

Definitely have had that noise from too loose belt deflection

Heck I keep an Allen wrench and end wrench in my handlebar bag and adjust deflection on the hill as needed just because I dont like giving up performance. It takes less time to adjust than stopping for a drink of water. Belt deflection is critical in having proper performing clutches. If it's to loose it's like starting off in high gear and affects performance all the way through the shift. It's also hard on belts having it to loose.

Same.

1/8” tee handle allen
7/16” box end wrench.

Forgot to give an update. I adjusted the deflection and the noise is now gone. Thanks so much for your help

Yea buddy!
