Drive belt / rear wheel alignment
My belt failed at 25k. The belt started to split on the left side so I checked my alignment. I used the the string method, and also measured from axel to swingarm pivots.
I discovered my wheel was not properly aligned. It was pointed to the left, which put extra strain on the outer edge of my belt.
When I aligned my wheel (axel) to the swing arm pivots, I had about .035 space on the right cam adjuster (in the photo).
I ended up welding a bead on the adjuster and grinding smooth to fill in the space, and match the left side cam.
Can you tell me the specific process youre using to check your alignment, or provide a link ? Thanks
- Remove the plastic covers from frame at the swingarm pivot (by the passenger peg mount)
- Then measure from the center of the pivot bolt, to the center of the axel, on both sides. The measurements should be the same.
You can tape pointers on a yard stick to make it easier to measure.

Anyway, I I ended up taking the mufflers back off so I could get my sockets and do it right. When I got the belt tension set, and started to tighten the cone nut to the proper torque, I kept having a problem with the cam (on the cone nut side) moving, and this would throw the whole adjustment off and Id have to do it all over again. It kept happening, I couldnt torque down the cone nut without the cam moving no matter what I did. The manual says to torque the cone nut to 22 foot lbs, adjust your belt tension (with the weld nut on the other side)and then torque to 95-105 lbs. I finally had to clamp a pair of vice grips right below the cam to keep it from moving. I was then able to torque the nut down but it was pretty frustrating, I was wondering if anyone had run into this issue and what you might do differently? BTW, I ended up with 1/2 inch of deflection...
I also wanted to check my alignment after reading gearheads comments, so I used a length of weed eater string to measure from the axle nut to the swingarm pivot, and came up with 18-3/8 inches on both sides. Although it might not be exact I do think its pretty close, I took several measurements ...
sorry for the length of this response, just a lot of info I wanted to include.
