bought the belt , loosened the top bolt . but the bottom just won't come loose. used wd-40 . i have an extra long ratchet but am hesitant to put that much force and break something. any other suggestions.?

I did mine two weeks ago and it was a little challange to loosen up the bottom bolt. I used a swivel ratchet with a long handle and put something behind the ratchet head and the frame to keep the socket from slipping off as you get it loose. Make sure you use a six point socket not an eight better chances of not rounding up the head. Putting a little pb blaster as best you can will help also just don't over spray that stuff is strong. Don't forget to put anti-sieze on the threads when you put the bottom bolt back on for next time. Good luck to ya
