Lol keep trying, make sure u are Turing it the right way, get a big azz pipe and put it on your ratchet as a breaker bar. It will eventually come loose

Like 6ft of pipe, I use my floor jack handle over my craftsman 1/2 rachet

heat it up with a little propane torch, then hit it with the impact, it will come right off.

Plus one on the flame wrench!

ill try heating it up see if that works

That one is a PITA. Impact worked for me. Thought it was going to snap. Good Idea on the heat.

PITA for sure. I thought i was going to break something too but it eventually broke free. It had some red loctite on it if i remember correctly. Thats what I puton it when I finished.

+1, it's a standard right hand thread, and torqued to 105 ft lbs.
And as said, heat the nut with a propane torch.

Plus One on the torque (105 ft lbs) when you are putting that puppy back on. You don't want that puppy to loosen up! I add a drop or two of blue locktite as well. Make sure the threads are clean when you put the nut back on so the locktite can give it a little stick.

Everything they said, that bad boy is on there like nobody's business! Took me over an hour, 2 different impacts, a breaker bar and a guy with a huge dht arm to break mine loose.

I used my Air Impact with 90 lbs. of air behind it and it took a while....

Make sure you get the grease off before you flame it.

I just use a 1/2 breaker.

 

[jones2507]

Finally got it off thanks guys

I've been lucky on the '06 and '08. Both spun off easy. A friend told me put the bike in neutral when using the impact wrench others have stated not to because you could damage the trans.

 

[Rocketmn]

Wow, good question. Never really thought about it. I have to find that out...it's gonna' bother me.

Dont forget the tab that is bent in to the spline, this has to be pryed to allow the nut to spin

Well, I'm over the hill, but I don't recall ever messing with a tab bent into the spline. It wouldn't be the first thing I've forgotten
