When I first discovered the worn-away tang of the steel washer, I thought that might explain the damage to the sleeve. But on second thought- the tang would keep the washer rotating with the intermediate shaft (usually near engine speed). Huh? It would make more sense to me if it were designed to be anti-rotation to the sleeve, so that relative motion would be between the steel washer and the bronze washer in front of it? So I'm faced with two puzzles- why this design
, and why did it fail.
