CFMoto 600 Touring - Noise from Primary Clutch Not Torqued Properly Causeing Rattle

[@slawdogshenanigans]

My Atv had a nasty rattle. After tearing into it, I found the main Nut on the primary clutch wasn’t torqued properly. After torquing, it silenced the issue. If anyone else out there has a noisy primary or rattles it could be this. Hope it helps!

How do you torque it down

[@slawdogshenanigans]

@@sposatoas258 with an impact gun. Just don’t run it too long or you’ll over torque it

[@brettbailey4293]

Will this cause a loss of power?

[@slawdogshenanigans]

@@brettbailey4293 it shouldn’t. Mine ran fine when it did this. Just annoyingly loud at idle that turns people’s heads with looks like “bro your new machine sounds like a chainsaw with a modified cam in it” lol

[@ryanschellenberg8810]

Did it get louder as you drove it?

[@Klinge_GER]

I have the same .. but when I torque the nut a bit stronger it disappears for a short time then the nut loosen again also with loctide blue ..

[@slawdogshenanigans]

You have to torque both the nut and the bolt down. Not just the nut. Try that. I did and never heard this noise again.

[@Klinge_GER]

@@slawdogshenanigans how much torque do you prefer? In the service manual are following specifications: nut 105nm / bolt 65nm but that’s a way to low. With that torque ist rattling as hell.

[@slawdogshenanigans]

I use an electric impact and hold it there for a good 3-4 seconds after stopping. I don’t measure it. Sorry

[@dannyo957416]

Does it make this noise randomly or all the time?

[@slawdogshenanigans]

Only at idle when the primary is disengaged

[@sniperman3863]

Mine does the same

[@slawdogshenanigans]

Either your main nut isn’t torqued or you need to replace the sliders.
