Belt Guard

[Kerrdog569]

I can say with a cat green secondary spring, it's NOT that easy. A Yamaha spring, yes it is that easy and quick. Plus on my Nytro I ditched the parking brake and all the other small unnecessary things for weight.

let me say it's no problem with Ulmers clutch kit I cant say with cats spring,but yes checking alignment and general services then it's not a bad idea

Last sled I owned it was 2 pins and the guard was off.

My last sled was a polaris rush and those clutch guards don't come off real easy either,oil tank and some electrical parts are on top of it,and you can't change that belt without their tool,lol

FWIW the polish I used is called Magic Mix and all of that black is oxidation that came off of a new machine. This stuff would do fantastic on a bare tunnel. No the clutch guard does not need to be pretty, but doing this now makes clean up that much easier down the road.

I'm not sure what the true long term protection level is, but I have some stuff from Liquitech that will protect once cleaned and polished.

Tried that on a tunnel once on a Nytro, didn't last long if I rode it like I wanted too. Now I just ride them and don't get to concerned about small scratches.

Looks great TD

I got really good at belt changes last year. I blew 5 of them. The worst part is the 8jp blows into a million pieces and the strings get pinched in the secondary as it closes. You have to pull it to get them out. I ended up carrying a utility knife and cut as much of them out as I could then install the clutch and new belt and rev the motor to clear the rest of them out. The strings get pinched and you cannot force the secondary open. Thank goodnes I got the secondary machined and am now running the 8 dn for this season.

But the tool makes it so easy on them and they do not blow belts. My 2011 800 Pro R had 3600 miles on the 1 belt, 2012 800 Pro R SB 2200 miles on its 1 belt and the 2013 PRo R800 Sb has 1860 on the first belt. Now I will see how many miles I can put on the Axys 800 SB on 1 belt.

I agree and my point was polaris even with a hard to remove belt guard is making their clutches easy to adjust belt deflection and changing the belt so why doesn't yamaha get out of the 80's and update the clutch so it's easier for people to make simple adjustments

 

[Yamadog]

Well that Polaris design was out of necessity cause the reverse runs the motor backwards and you cannot just rotate the secondary to undo the belt. I agree it would not be hard to put a threaded hole in the helix and do the same thing but really it is not hard to change the belt and the way the chords bind in the clutch I doubt that would work anyhow.

No changing the belt is easy but I see some other people have complained I'm mostly referring to the silly little washer and bolt crap on the back of the clutch,not that ya need to adjust belt deflection that often

And yes the compression springs make it tough to rotate the secondary like we can on our torsional spring yamaha's

I got ya Kerrdog ya know they would have to charge another $34.50 for the sled then

Yeah the belts on mine deflect then blow no adjustment necessary

It just frustrates me they had a belt that has worked for years and several aftermarket manu. made belts to match. Why the 8 jp was made of different dimensions and compounds beats me. The only testing they did was on 125 HP stock sleds and I guess the 8jp is fine for that.

It (the 8JP) wasn't even good enough for my stock machine. I went through 2 of them in 2000 miles this winter and they both have some pretty good wear marks and the black is all over the inside of the tunnel and I had to use some light emery cloth to get it all off my clutches. Having been riding Yamaha's with 8DN's all these years I was like what, I have to change a belt in the middle of the season. What's up with that?
