fyi

ive had one "black Friday" hub that wasn't machined with a proper nose radius where it sits into the pulley.

fixed it by zip tying the bbv closed and letting it idle to turn the blower without the belt and I used a bastard file to touch up the radius....just went a little at a time till it bolted flush and didn't wobble.

then just popped off the ziptie and put the belt on
