Rear Wheel Nut Galling Problem?

Hi gurus

Just read Ade Critten's post from about a year back regarding the rear wheel nut sticking/galling.

I think I may have this problem, I've had the rear wheel off before (bike's done ~15.7k KMs), recently tried but couldn't budge the nut. Tried breaker bars (1ft, 3ft), extensions, even took it to a car and a specialist Duc shop; tried to impact the sucker off with no luck

Is there any other way to get the *&^% nut off?? I was thinking maybe loosening the hub and sprocket side nut to free the axle somewhat to ease off any pinching pressure on the rear nut so that I can try the breaker bar; but from the manuals I believe the caliper bracket assy prevents this?

Any ideas? Thanks in advance

beearch;
leave the axle assy in the swing arm....its easier to hang on to
(it will come out, remove the leftside nut/sprocket carrier and drop the caliper)

here's a link to a product that should be in everyone's tool box Aero-Kroil
http://www.kanolabs.com/

makes Liquid Wrench look like LocTite!

you'll need 3-4 drops in both between the wheel/nut and nut/axle.....welcome to the world of dissimilar metals, give it a day or 2 to soak through

i can remove, it without the Kroil......i have a Swench wrench puts out 800 lb/ft looks like a big ratchet wrench....use the Kroil

this is why i put NeverSeize on mine

Would I still need to do all that if I'm using the Kroil? Or can I simply spray/drop Kroil into the threads and give it a shot again with the socket?

Yep, well aware of that, I got the wheel off it previously (changing tyres) using only a breaker bar but this time she won't budge at all, even after 1/2 a can of WD40...!

I agree with Noel about the Kroil. A must have product.

Using a steel socket and an impact wrench will get that nut off. It may take a while, and you will certainly damage the finish on the nut, but it will come off.

I had the same problem when I had a F4 750 what i did was, take the bike off the stand, face the front wheel againest a wall, have somebody seat on the bike with all there wieght over the rear of the bike and standing on the rear brake. Then use two, 3 foot breaker bars, one person pushing down and the other pulling up. If this still doesn't do it you are in big trouble my friend.

PS don't forget the WD40 and once you get it off use carbon/copper grease.

beearch;
clean the WD-40 off with solvent, its not a penetrant
Kroil is ....benchrest shooters use it to remove the cupronickel bullet jacketing from their barrels, and that is smeared on with 50,000psi!
it enabled me to remove the rusted bumper bolts from my work truck, parked outside at the beach for 40 years......and they are the reason nut splitters were invented

after letting the Kroil soak in for a day or so use, stephen wood's method

before putting the wheel back on use copper slip or Never Seize on the surfaces

Or you can apply a thin coat of grease to the threads as the book says...
