I know the thread is older but just wanted to weigh in, perhaps I got lucky but my Pulley Nut came off pretty easy.

I have a decent craftsman torque wrench I got from sears a while back and after all the threads I read I was worried about getting the nut off or having to drill it. I went ahead and ordered a new nut too.

put the impact on it with 90psi compressor pressure, 10 seconds the holder came loose, put it on correctly, 10 more seconds the nut was off.

Job was pretty easy otherwise, just trying to give some confidence to those on the fence about it!


Rain came, so can't comment on the acceleration yet!
