Dont use square. .use allen side..
just like on car...its how to hold pulley so you can use that amount of force
Ahh OK. So use the same allen side as when I took off the car. That makes life easier as I can get a lot more grip over there. The left hand thread plays tricks on the mind because you feel like you're over tightening and going to break it but your'e actually loosening.
Like you say just figuring out a way to hold that sucker is going to be key here. I'll see what I can rig up.
