You got the part that it calls for. I'd still take your old belt to TSC and get a couple that are shorter than what you have. I just went through the same deal on one of my 2182's with a 60" Haban. I was basically Bush hogging with it, something that I know is wrong and picked up a branch that caused the PTO belt to jump off the deck pulley. Long story short it destroyed the belt so off to TSC we go pick up 3 different size belts and use the one that fits the best. The supposed Cub size and what I ended up using don't jive. BTDT.
