Guys, yes that bolt is on there tight, but it was a very simple removal using leverage.

Use your ratchet, or better yet, breaker bar, coupled with a long stick/pole. I used the long metal one that is used on floor jacks (depends on the type you have). Mine was perhaps roughly 3-4 feet long with a hollow end that I was able to slip over the ratchet/breaker-bar. Didn't require much force to remove at all, using this leverage.

And if you don't have the pulley holding tool, depending of the type of pulley you purchased, you may not even need one. For the 4" pulley I installed, I just slipped a bolt through one of the holes in the pulley through the hole in the block to hold it in place.

Hope his helps!
