Only reasons I have seen a belt jump:
-Accessory bearing has failed and is binding where requires too much effort to start turning. Belt will just get yanked off the pulley… especially when cold.

:tup: thanks for the info. The think that’s the most likely coulprit.
This was the other thing i wanted to check, i do have an idler pully after the S/C drive pulley.
My reasoning is this. If the belt is jumping the S/C drive pulley, the idler pully which is next in line past the drive pulley in rotation. This idler pulley could be seizing up causing a “back up” in the belt which gives access play in the belt as it goes around my drive pulley.
kinda like if you have a taunt rope moving infront of you and you grab it…you know have access tension on one side and slack in the other side
