I used a long soaking of Liquid Wrench, and my 1.5' breaker bar on that bad boy and got it off all by myself!
Before it broke loose, I was pulling on the bar so hard, it was litterally deflecting about 10 inches. :shock: And when it broke loose, it sounded like a .22 caliber bullet being fired, and tossed me on to the floor of my garage!
I thought I had to have broken something in there, but when I took a look, the crank bolt was finger loose, and all I had to do was unscrew it by hand, and swap the pully!
