Ok perfect. I race a car with a 440 pro x in it and I was trying to find out how to adjust the clutch to launch a bit quicker. This is perfect.

torquing is important,70 psi at first then back off and retorque to 48psi approx,makes a difference where the primary sheave engages the belt.Thanks for posting.

I'm going to shim my 340cc. Gonna make it hit hard.😮

Dude, I shredded a belt getting stuck in heavy wet snow. Yamanha Triple 7. But now my sleds clutch doesn't engage until 5k RPM. I'm new to sledding & learning a lot. Previous belt engaged around 4k. I think I might need a new spring or rebuild primary. Thanks for the vid tho, certainly helpful.

Thanks! Great video, I learned a lot!

Excellent video

Wow! Thank you!

Or you could buy a spring with more preload.

so this will make the cluch engage at a lower rpm ?

Higher rpm.

Hmmm ok. Does that affect the top end ? Does that affect the acceleration? I’m confused ?

@@Metcalferacing_29 it shouldn't effect the top speed. It just helps launch a little harder. Quicker acceleration off the line.

Do you know how to split the sheaves on this clutch?

I haven't done it on one of these. I have on polaris, but I'm sure they're different.

@Whitestrash thanks for the reply. Yeah, possibly because I can't seem to split it apart.

@@TheHunter1o1 I know on polaris you need a special tool for the spider and it takes like 250 ft lbs to break it loose.
