new and improved direct drive couplers with the metal inserts
It's the same old coupler with the metal inserts that they have always had right, or did they make some change to the coupler with metal inserts that I don't know about?
If it's the same coupler with metal inserts as always that coupler has been out for years now, don't know that I would call it new anymore.
I have never seen a gear box shaft strip out like that and I have put a ton of the 'new' couplers on.
Going to say what you run into there is a fluke thing. How old was the washer?
