NC30 rear wheel spacer

[Chaosfruitbat]

I had the same problem. In the end, I removed the rear caliper and then slide the hub assembly off from the 'wrong' side. With the wheel out, I heated the hub with a hot air gun and then hit it with a big hammer. Once I had the wheel off the hub, I wet and dried off any corrosion, and colpaslipped it all back together.

Let me know how you get on!

Bike must have been laid up a while, my rear wheel comes off once a year for a tyre.
Like you said, wait to get the front end on the ground, most of the energy is probably being absorbed by the bike swinging about.
Keep at it and good luck matey

Hey guys, happy new year to all of you!
Well the front end is all back together and firmly on the ground, ive been out and been hitting the $#1! out of the wheel with a combination of a big hammer and wooden drift but still no luck. Ive tried everything; blowtorch, pentrating fluid, heat gun, Huge hammer, drifts and im all out of ideas!

The only tuing i can think of now is to try the method mentioned above by chaosfruitbat about removing the rear hub, but ive heard this is a pig of a job what with the huge nut torqued up to a million NM and so on...

Is it as simple as undoing the hub nut, rear caliper and slackning off the pinch bolts, sliding it out of the other side?

Again all advice is truley appreciated,
Thanks, james

Yep it is pretty much that simple. The hub nut is about 140nm so is pretty tight but nothing that a decent length breaker bar wouldn't sort. Famous last words i bet! Post a couple of pics so I can see if you're on the right tracks.
Good luck.

Ok thanks mick, heres a quick pic... the wheel nut and spacer are removed leaving the wheel still somehow attached by mass corrosion im guessing.

So I gues this is the nut (46mm) I need to un-tang and remove, followed by unmounting the brake caliper, loosening the chain adjuster pinch bolt and adjust and remove the chain and sprocket, then it should all slide out of the right hand side... am I on the right lines?

Obviously all of this after suspending the rear end of the bike and removing the paddock stand...




regards,
James

Yep you're on the right lines. When you manage to remove the it you might be able to get a drift at the back of the wheel and give it some persuasion.
I'm really suprised your wheel hasn't given in now, this must be the worst case I've ever heard of.

Thanks for the help, today I managed to undo the 46mm hub nut and slide the whole hub and wheel off as planned, once the wheel was off I was able to really give it a hammering in several different directions. After a couple of hours, blowtorch, drift and lump hammer the hub came free of the wheel! yay

After some inspection there was a lot of corrosion and it even left a couple of the locating "spikes" in the wheel which i managed to remove with the help of an airgun. All in all Im pretty happy and will make sure I sand down the corrson and use a small amount of copper grease between the two surfaces before putting it all back together.

Thanks again to all those who gave advice!

Nice result in the end mate.
