Help grinding off seized rear axle nut

[phyx1u5]

Hi Everyone,
Im after a little help. Just wondering if anyone can grind off the seized rear axle nut on my yamaha r1 for me? Preferably based on the north shore. I understand if there is a fee for your services but i really need this damn nut off so i can ride again. Iv tried every means possible (no longer able to torque the nut as the blocker plate on the opposite side of the axle has given way so it just spins free when you try to torque the nut ) and have resulted in needing to get it ground off, and as i dont have a grinder i cant do this If the axle is required to be cut off in the process then so be it....

I havent been able to take any pics yet as i dont have a camera but, will try to upload some if it will help understand the problem.

Any replies much appreciated

Thanks all

have you access to an electric drill?
If so, drill a hole across the nut and split it.
this will release the "grip" on the bolt and it will undo.

I am presuming this is a castle nut, so the drill size should match the size of the castle slot.
A shard cold chisel and one sharp hit with a hammer should split the nut.

I hope this makes sense to you

this is a castle nut

Thanks for the reply mate,
unfortunately this isnt a castle nut, its one of those self locking types.
heres a link of a picture of what the nut looks like (this is not taken from my bike) http://www.tastynuts.com/acatalog/TISPYAM01GFITTED.jpg
Im thinking, grind it down to as close to the thread as estimatable then crack the rest open with a cold chisel, either that or just grind right through the axle as i have a new axle from a wrecked bike on the way.

Any chance you could say attach a set of vice-grips to the other side,wedge it to stop them spinning then undo the axle nut?

the question you should be asking yourself is "how did it seize in the first place?"

number of ways to get it off without cutting the axle, relative simple job.

Err maybe you could tell him.

Where on the North Shore are you?

[Subike]

that flange nut can be cut off the same way as I described.
You just have to be more carefull with your drill so you dont damage the thread,
But if you are prepared to replace the axle then just use a grinder,
make sure you use some anti seize on the new nut when you replace the unit.
Its a pity you did not have access to a rattle gun, that would remove it in seconds

Indeed if you have a solution please do tell.
vice grips wont work as there is not enough clearance above and below the axle.
Im located in mairangi Bay.
I bought the bike 2nd hand and this is the first time ive tried to remove the rear axle as i wanted to change out the chain. Im assuming either waaaaay too much loctite or just rusting at the thread interface somehow, either way its seized pretty good.
Ive tried wedging a plate in between the block and axle, tried heating it to 250c, cooling it to minus 20, tried every damn thing and finally given up.
As i said ive already got an axle and all the bits on the way so im just gonna grind it off, wasted enough money already trying other methods.

yeah unfortunately i didnt have access to an air comp. Although im skeptical on whether a rattle gun would actually work. The nut at first was coming off fine, then it just got harder and harder to undo till finally the axle punched through the block on the other side.

with this added information, you created your own problem'
How?
Friction creates heat, think about it.

well in hindsight yes i did, but at the time i was none the wiser.

you could always buy one of them cheap grinders from the wharehouse or bunnings etc they're only $20 or so..

Found out one of my mates dad had a grinder so i borrowed his.
Wow it was a B*tch to get off, literally ground down half the fricken nut. On the inside found that the thread had grooved off so it was holding onto the axle.
looks like the nut wasnt even OEM, so there you go, always buy OEM!! why the previous owner put an after market nut on is beyond me.
Anyways thanks all for your help guys.
