SDCE problem
If the belt is moving towards the engine on the tensioner try to shim that pulley a little but (.020 at a time). In 4 years I had it jump one time, and that was because I was in a hurry and left off one of the spacers on a standoff. But even with the spacer off I put the belt back on right, made 6 passes and the belt never jumped again that day.
