Replace the belt with popo #148 ; it's streched when it got hot . Mine did the same thing , R & R ' d belt and no slappin' . The 148 is the stock ' 14 belt . Works for me .

 

Naw mine is a 15 and I've never had this problem before. I'm not going to put a 14 belt on even though I know you can. One, it'll screw up my clutching.

It's a brand new gates belt, I was just breaking it in..got about 20 miles on it.

Ya I tried that too . I have a '14 xp41k with ' 15 cover and belt ; the ' 15 cool belt got hot & started slappin . Problem solved with new stock ' 14 belt . Give it a try and let us know how it works .

 

I recd the 48 belt also, and what makes you think it will mess up your clutching? Also the slapping is what causes the belts to break.

 

Have you checked to make sure you have proper clutch spacing. If there to close the belt will slack out and cause it to hit more than normal. Proper space is 10 1/2" I also installed the slide guide. Gives a slicker surface for the belt to ride on and bolts exactly in the spot your talking about.

 

How do you like that slide guide? Just got mine from hunterworks today. Pretty excited to see how it works.

 

Yeah thought about both of those moto. Don't really want to spend $100 for a piece of plastic but...might have to. I'll barrow a friend's spacing tool, that might be it.

Darter..maybe I'm wrong, correct me if so, but if I'm set up perfect with my weights for the 15 belt won't a shorter belt throw my rpm off a bit? Not talking drastically here..

I happen to have a brand new 14' OEM belt so I can try it as an experiment I guess.

Shaft spacing is the most likely culprit and the 15 belt is only 190 thousandths longer. but in reality not longer at all on the clutches, it is wider and thicker too so it crosses all that out.

The belt is not why it is hitting

The guide so far seems to be doing its job. Got about 130 miles on the belt since install and doing good. I have pulled the cover and can see where it's still hitting the guide but it's doing what it's supposed to. I checked spacing and went to a '15 gates carbon when I put it on also did now rollers in the secondary and new hd spider. I was breaking belts about ever 70 to 85 miles. Have about 1000 miles on the car now.

On a separate note I did destroy the primary due to the primary spider backing off just before thanksgiving. Man that was expensive. Thanks again Polaris.

 

Could you hear it hitting before installing the guide and can you still now?

Damn 75-85mi per belt is crazy. My stock polaris belt is still in tact. 1000 hard dune miles on car, didn't blow a belt til I clutched the car and put a gates on. I think I was to light on the weights. Weights are perfect now..just gotta stop this belt slap.

Could not hear it before and cannot hear it now. Mine was hitting where the exhaust tube and housing meet it would catch the ribs on the belt and blow it to pieces you could see where it was starting to pull the plastic down and make it even worse.

 

Yeah I've seen pics of that. Mine isn't catching now but if I let this go it will eventually. Thanks for the heads up.

Just did a clutch kit and Fuel Customs cover today. My car only has 400+ miles. Mostly dunes. Inside the cover you could already see where the belt has been rubbing. I was surprised. Fuel cover is so much bigger it shouldn't be a problem anymore.

Thanks Todd I'll check the spacing.

:drive1:YO DONNY ; Thanks for backin me up on the 48 belt ! Your machines have a lot of up-grades and a ton of power . I would think you have been thru it all . 2200 miles ( two years ) , stock clutch with POPO heleix up-grade , '15 cover and all stock motor . Glazed one ' 14 belt in Moab rockcrawlin ( driver error on a nasty ledge ) , ' 15 cool belt started slappin in Ocitillo Wells in the sand dunes (got hot and streched ) , still runnin my third belt ; stock ' 14 . I talked with Todd at lenth a while back and he recd the ' 14 belt without any clutch upgrades ( He's a straight shooter , didn't hard sell me on clutch kit ) . I know each driver is different in how they operate their machine and the sand tends to be a destroyer of clutches . I believe that if all is set-up properly , the plastic guide is a moot point . Just this mans opinion and oh by the way , I beat the hell out of this car ! . No trailer queen !

 

It's not that difficult. Easier with 2 people. You have to remove both primary and secondary clutches and you don't have to have the alignment tool but I would advise just to spend the few bucks to buy one. The center to center of the shafts should be 10.5 inches. You loosen the bolts that hold the trans to the motor and that acts as your pivot to add or subtract spacing. I'm sure someone can provide a better description. I've done it once and it wasn't that bad

 

Robb make sure that's not the timing chain slapping on start up.

will do, good thinking.

 

So a little update. Pulled my cover/belt/clutches and inner cover to fix the spacing. When I did, I was beyond pissed to see my belt with only 20 break in miles on it destroyed. The top was torn right off in a 3 inch section from hitting the top. 20 miles!

So I adjusted the tranny and fixed the spacing...now I get to spend $180 on that white piece of plastic and another belt.

Kit, belts, tools, rollers, sliders, more belts, more tools...this clutch shit is never ending.

Order incoming Todd.

Call or email me and tell me about your spacing and alignment

 

How far out was it?

I know the feeling.
Clutch kit. $350
8 blown belts plus the 4 spares I currently have $65 a piece
Rollers $60
Hd spider. $35
New primary $650
Aftermarket vents for the cover $50
Slide guide $100

Little over $2000 in and I'm sure I'm still not done. And that doesn't include the 3 tools to assemble/disassemble.

Thanks Polaris.

 

sin city,
was it out of udjustment?.. Were the adjustment bolts loose?

 

It was about 10 and 5/8th. So 1/8 out. The tool still went on it just didn't slide on and on freely..it binded a little, like the shaft was tweaked a tiny bit. None of the bolts were loose, after I got them all loose I was able to get the tranny to a point where the tool would slide very nicely on and off with no binding. After the torque sequence it stayed pretty close and I was happy enough to call it good. Measures pretty close to 10.5 now.

I may or may not need that white slider at this point but I'm not risking it. Destroying a belt after 20 easy break in miles is absolutely ridiculous.

what about alignment though not spacing?

 

Not positive how to check that. Nothing is back together...waiting on your stuff

Todd,
Were is the video on spacing and alignment between secondary and primary. Great videos on your sight but I don't see this one!!

 

Because I don't have one, never done it myself

No one around here has a XP1000 of any year, po folks here and no sand dunes!!! LOL

 

Lol.

It's not hard squaredaway, shoot me a pm if you need help.

Todd get off the forum and ship my items!

Our new fuel customs clutch cover fixes all that. no more beltslap and it stay 40 degrees cooler than the corrected belt housing from polaris.
