I've been working at the thing, probably hasn't been changed in years, its worn pretty bad and has been slipping. Bought a 14 tooth to for higher top end and can't get the main bolt loose.

Its: In first gear, have the rear wheels blocked by blocks, i have a log on the left footpeg to support the socket extension and I'm sitting on it going counter clockwise pushing down with a breaker bar. I am pretty strong, anyone have any tips other than power tools?

Thanks for any feedback

 

Stand on the breaker bar and have a friend smack the bar with a hammer. Your constant downward pressure plus the sudden downward force of the hammer might knock it loose. Other than that, try heat. Penetrating oil might help too.

 

Impact wrench is the best way to go.

 

Wedged atv against a post with the wheels locked in first while standing on one wheel and knee on the back seat, proceeded to kick it neatly very hard after lots of penetrating oil. Was a bitch but rides great now, took me like an hour of thinking of new ideas and walking in circles to get.
