So i get the new belt on and wound up snapping the long bolt. Broke it off flush with the adjuster. Pretty sure it was because i tightened the pulley first. Why? I dont know. Anyway, for those of you replacing the belt for the first time or whatever, tighten the pulley LAST. Otherwise, the adjuster binds against the accessory bracket, which is what i assume happened. Had to remove the pulley to remove the belt.

I was able to remove what was left of the long bolt from the adjuster using the bench vice (vice grips did not work for me) and the pulley bolt. Slid a box wrench over the threaded end of the pulley bolt and threaded the bolt onto the adjuster by hand as far as it would go. Then clamped the broken bolt into the vice. Using the wrench as a breaker bar, i spun the adjuster off the broken bolt. The threads in the adjuster and pulley bolt were good to go. No damage.

BTW, is the 4792 112 stamped into the pulley an OEM part number? I assume so, but need to be sure before ordering a replacement. Thanks.
