Thanks Jim. I checked the compressor first thing after it spit the belt. Checked everything to make sure it’s tight and smooth. Replaced the idler and tensioner.

Vince, you hit it and i thank you. I didn't know or think about the pin. I don't wrench much any more, at least on cars. The last tensioner i replaced was more than twenty years ago on my 300E. I got to the hangar this morning and snaked the belt in place, levered it over, pulled out the pin and all is well. I have even driven it over a hundred miles today with no problem.

The technical side of this forum continues to be incredibly awesome. Thanks guys!

By the way, when you get my dunce cap ready, let me know and i will supply an address.
