I took my Belt that came with my Ranger when i bought it and measured the o.d. which was 41 1/4" ( the manual calls for it to be 41.225 to 41.422 ). I bought a new factory belt for a spare i measured it and it measure out of tolerance at 41.5". I bought a Dragon Fire Belt which Measures 39 3/4" o.d so you can see a big differance in outside diameters. This will make a big differance in the way the machine performs. This is why the shorter sp belt is working so good as is the Dragon Fire belt, which im running now.
( the differrence is stock belt 5900 rpms and 39 mph Dragon fire belt 6100 rpms and 43 mph )

Did you try to return the out of spec belt to the dealer?

No i took my old belt off and was going to use it for the spare and i ran the new belt, but i lost performance and i started checking out why and found this out. So now i have got two spares.

Does the shorter belt make it difficult to shift?

some harder than stock belt.

I've had a SP belt hanging in the garage for sometime now and have never put it on. I had read several different posts in the few months about the SP belt making harder to shift but then also read where it shifts a little easier after you've ran it a while. A few weeks ago Mark's staock belt exploded into a million pieces and at the time the only belt available was my SP belt. So we slapped it on and give it a try. I will have to say that it was very difficult to change gears. It took off and performed fine but man was it hard to shift.

Brian, Is he using the SP belt still and have it had any other problems to the motor, like the motor mount etc.

I put the SP belt on my 500 and had to adjust the motor back(loosen the belt) to get it to shift. It was grabbing the drive clutch and spining the driven clutch to fast at idle.

We didn't have any problems with the belt wanting to grab at idle it seems to be fine. The hard shifting was the only thing that wasn't all that great. Mark just used the belt for a few minutes to get his Ranger loaded and unloaded and then he replaced it with an actual XP belt.

Barry, I don't know if you can adjust the motor back on 07 700XP ;-)

 

[alnash]

You can, but you have to loosen all motor mounts and you can slide back some. The easy way is to add shims between the sheaves of the secondary clutch. I don't know for sure but i think you have to have a roller clutch to do this.
