Message zero deflection...the point of my post was to ask if i'm out of
spec (<1/4"), is it still safe to tighten if the belt is squealing?
Right now I'm at spec and for now, knock on wood, with the
new belt on there are no problems. i was thinking that i'd
allow for some belt stretch and turn the tensioner bolt a bit
again once the squeal picked up.

my belts aren't disintegrating, they're tearing...somehow it's
jumping out of the grooves and getting caught in the other
moving belts.

i'll tighten it slightly if it starts to squeal, and if i keep having
trouble i'll take the belts off and inspect the grooves. makes
sense that the squealing could be caused by wear on the
sides of the grooves since that's where the belts get their
friction.

i wouldn't be surprised if the pulley is just worn since aluminum
is so soft...i'm being lazy by not searching before i ask, but
what's the expected life of the U/R pulleys?
