Bought this belt for SP4012
I was thinking I was saving some money and going to try a new brand versus buying from the dealer. I've been in business for over 7yrs, and the top grinder in the county. I have changed and aligned these polychains numerous times to spec. This belt literally snapped and shredded like I have never seen before. I've knocked off teeth even torn stock ones but never have I seen one almost disintegrate on me, shredding vertically and horizontally.
(This picture was taken after I had loosen the bottom pulley and pushed it back to see all the fiber/shredding caught in the clean out pan.)
