Hi all I am new to this forum and hope someone can help point me in the right direction.

I have a 2006 Sportsman 450. Recently I had the belt replaced due to slipping and kinda notice or at least thought that once I got it back from the shop it seemed like it was kinda dragging or not pulling like it was before. The best way I can describe it is it feels like I'm pulling a weight behind me.

anyway, I just blew it off to being my imagination until tonight. I was out on a trail and under light throttle all seemed fine, but once I got into the throttle around 4 to 5500 rpms the engine would speed up and finally I'd feel it grab and then all would be fine until I slowed down and did it again.

Kinda like a belt slipping, but I'm pretty sure it wasn't because I never smelled anything like burnt rubber.

I hope this makes sense and someone can point me in the right location.

 

welcome to the forum,it might be your secondary buttons, they could tend to keep you from going anywhere,take the clutch cover off,wear safety glasses, be very careful of the spinning stuff,have it in neutral and give it some throttle and watch for smooth operation of first the primary belt coming up and also the secondary belt dropping down.should not have to overrev,i spend as little time as possible,maybe the secondary is not dropin down smoothly or at all,the belt should be sitting slightly above the top of the sec. non running.don't do any of this if your not comfortable,,,,,,,,,,,,,,,,,,,

 

Thanks MECHANIKE I appreciate your response. I am pretty comfortable with the inspection of all of the parts, but I have never changed the buttons or taken either the primary or secondary apart. I have a read a few post on here and have seen where certain tools(that I may not have) would be handy.

I did what you described last night, but I had it in park, not neutral when I checked it. Does that make a difference? The transition on both the Prim and Sec seemed smooth to me. I'm just hoping I don't have to throw a ton of money at it right now, but I guess that's the way it goes.

Say the transition on prim and Sec is smooth, what next? I will more than likely take it to a shop and have them do the work due to lack of a couple of tools, I just want to have a good idea of what it may be so i don't get caught of guard.

thanks again.

make sure they did knot put the wrong belt on,take a paper towel and run it along the pully belt running surfaces and see if anything comes off on it,if the guy that worked on it had greasy hands could make slip +not have to have a smell,talk to the guy and see if he checked the buttons,,,,,,,,,,,

 

I would double check the belt to make sure it was correct. The number should be stamped on it. If it is the correct belt clean the clutches real good.

Other causes could be worn clutch bushings and/or buttons. Broken or loose motor or tranny mounts allowing them to flex and slip the belt. Also check the primary clutch for grooves in it where the belt has worn the clutch. This usually happens just a little towards the outside of the clutch from the center hub. If it has a deep enough groove the belt will get stuck in there and can slip until you give it enough gas to force the belt out of it. Good Luck

 

UPDATE!!!!! Shop called and said it's the primary.........all jacked up at this point so looks like I'm on the hook for a few dollars. I'll give details later if anyone wants them.

 

Make sure if you get a new clutch, you get to keep the old one for parts

 

why is it the primary i would want to know and see what is gone (if anything) my guess would have been the secondary buttons as well.

 

Mechanic said my clutch and belt cover had a hole in the bottom(I discovered that my self too) and the water, mud and sand had taken it toll on the primary and deep grooves worn too much to clean up.. The secondary looked good according to him. So, there you have it.

 

Sounds like belt was bad for awhile and coming apart and slappin the cover.
