New belt loose and slipping

Hey guys I'm new to owning a Polaris. I have been doing a lot of work on my used 2001 Sportsman 400 4x4. I had noticed the new belt was loose that I installed but didn't know how to tighten it so I took it for a ride this weekend to see how it ran. It ran well on flat ground but when it came to small hills or any incline it had no power. It progressively got worse and I had to turn around and end my trip. I could hear the belt smacking the plastic inside the clutch cover and it was smoking bad so I know it is loose. It was a brand new OEM belt. I'm a DIYer so I don't want to take it to a dealer. Is there a way to tighten the belt or do my clutches need replaced? Will a clutch kit like EPI offers fix the problem or will it continue? Thanks for all suggestions or ideas!

Good morning playa and WELCOME!

I would look closely at your motor mounts. Then pull the CVT cover and before you touch anything, look at the belts alignment. It should be straight form front to rear sheaves, not angled at all. Also can you read the letters on belt? It should be installed so you can read them as you stand on the side of the machine.

I would dress the sheaves with a scotch brite pad followed by a good cleaning.

If the belt is shredded, be sure to vac out everything, including the ducting as pieces can find where way back in to the cover and waste your next belt.

Be sure you have installed the correct factory belt.

Good luck,
CW

Thanks CW, I will take my CVT cover off today and take another look and also make sure I have the right OEM belt for my machine. As far as checking my motor mounts, am I checking tightness, alignment or ?? I bought this wheeler as a project and it has been just that as I learn more and more. I'll keep you posted on what I discover.

I'm assuming you are going to find them broken. Usually the rubber pulls from the steel. You will need to gently pry. Lifting or torqueing engine. You will see it/them separate.

Ok, so the belt was aligned properly and it was the correct OEM belt for the machine and installed so I could read the letters from the left side of the bike. I watched it slipping on the primary clutch when reved up in neutral. I removed the secondary and can hear something small rattling around inside. I have a clutch puller and ATV coil spring compressor ordered. So I guess now I have to wait...once I have every thing apart I will be able to assess the issues. I saw some clutch kits available online as well as rebuild kits. Not sure which one I will need. The teeth on the belt were in decent shape but pretty glazed on the sides from slipping. Anything I am missing?
