me a picture of the harmonic balancer that belongs on the
car? And give me some ideas on what it could be?

Why did it need the harmonic balanced replaced? You don't mention when it comes off idling or underload? If there were no issues with the serpentine derailing before the New balancer was installed.. I suggest you check it first, having a belt derail from alignment is a common issue... or a worn tensioner. The Eaton places a lot of load on a belt and if the balancer is "wrong" undersized in diameter it will toss the stock length serpentine.

It pops off at idle
