I haven't taken the belt off to check yet but from the sound of it,
I'm not sold on doing it myself considering i have the least mechanical
apptitude of anyone i know but i guess i don't have much of a choice....
Mike, doing the coupler on an M90 (as opposed to us poor M62 guys) is the easiest chore you can do. VERY simple. You don't need to remove the entire supercharger, just the nosedrive. 30 bucks for the coupler, a couple bottles of oil, and some gasket maker. Most rookies pull this off in 2-4 hours.
