On the right is an example of why you cannot machine the third pulley (PS) off of an RB26 crank pulley. There was really no way of knowing that this would happen by visually inspecting the part...
The lesson learned is quantified by the 510 dollar ATI superdamper (center) and the accompanying waterpump pulley (to clear the larger damper). However, this is supposed to be an EXCELLENT addition to the motor, greatly increasing longevity, so it's not all in vain.
