I had to use heat and an air impact gun to get mine loose!! I recommend getting the right socket size because if it is really tight you do not want to strip that nut.[sm=noooo.gif] Then you will be in a world of s**t!![sm=smiley19.gif]

 

I haven't tried it, but I'm with Marty. Sometimes it pays to read the book. Page 10-4 in the Service manual supplement indicates that it is necessary to "flatten out the bended washer" before trying to remove the nut...

 

Having just gone through the ordeal this afternoon, I can relate. Other than unbending the retaining washer, a 17" breaker bar with a 27 mm socket did the trick. I had my girlfriend standing on the rear brake for me ... so rowdy comments about the nut's family lineage didn't seem to be too professional.

FYI - Tried a hand impact driver for a while, but that got me nowhere in a hurry. I also sprayed the nut with WD-40 last night and again this afternoon ... don't know if that helped or not.

Thanks, but my tab was out of the way and it still would not come off and I don't think you can even get the socket on the nut with the tab bent down. They had to have used some sort of lock tight, can't imagine the nut being that tight without stripping the threads.

 

Got mine loose by using my floor jack handle on the end of my 16" half inch drive ratchet, I slid a long 3/8 drive extention though the rear sprocket slot across the swing arm..... I dont think anything else would have worked,,that thing was friggin tight!!

 

Just broke my front sprocket nutfree. It would not budge until I did swear at the thing! 27mm, standard thread. New dimple in swing armfrom a wrench jammed into the rear sprocket.........

 

I bought an 1/2 inchelectric impact gun from www.harborfreight.com.

It was $79.95 and it took off the nut instantaneously.

I just got a flyer in the mail and they have it on sale nowfor $39.95! That's an absolute steal!
It doesn't help me though....

 

I loaded mine with pentration oil for a half hour then heated with a propane torch (not too much there is a seal behind the nut) Then it did come off finally

 

I had to use a 2foot breaker bar plus 2 more feet of pipe after that to get it loose it went prety easy
