Hey Paul,
For what it's worth here is a quick run of the water pump pulley.  100

lbs at about mid belts

location.  0.025" thick steel.  Left off the thick pulley - modeled it

as rigid.

Isn't the internet and amazing thing? Thanks Dan.

bolts.  8 bolts fixed and load same direction.  With 8 bolts, the stress
values are reduced by 50%.....
