COG SC belt keeps shredding help
 

Replaced the belts last year the sc belt completely broke. Put on a new belt made sure it was loose enough to move back and forth on the pulley. Today I noticed it was fraying and I don't know why?

is this the correct belt for your application?

It appears your belt has Round teeth and you have square cogs on your pulleys.

Which leads me to think you have the incorrect belt. It will slip

I know this beause, my old D21 pickup chnaged the timing belt style (round to square teeth) mid production. If you went to the parts guy and told him just the year and make you would get handed either style. If the parts guy was observant and noted this, he would ask you for your VIN number.

It's hard to tell from pictures how square your pulley teeth are. This is my guess. (doesn't help when it's only $17 and made in PRC ;) )

Also, I don't think this belt was designed for superchargers.

What does the warning note say on the belt? (just after the part number it says "do not....." (2nd picture down)

This was the exact belt that was on it when bought so I just went with the same belt Titan Motorsports was the one that built and worked on the car. I don't know if it's ideal. The warning says do not crimp. 560-8m co722 70 rib belt
