Removing the rotor nut - What direction ?
 

God its sooo tight !

Can I just confirm, does anyone know if this is a left or right hand thread..

Left hand threat being that you tighten it ANTI-Clockwise.

Thanks

Hi
I had the same trouble. It's a normal thread - that is you turn it anti clockwise to loosen it. When loosened you will find an even bigger problem - pulling the rotor. Use the most robust puller you can find and be careful not to distort the thread on the end of the shaft. Good luck. Be brave.

AAAAAAHHHH

Thanks Bernard. Out of the countless bikes iv done over the years, this is the first conventional thread on the rotor...

No wonder its no tight :)

To hold the rotor I used a chain wrench. Draper do one withe a mole grip like adjustment. It's expensive at about £30 but it does the trick.

hmmm. Got the nut off now with a BIG airgun. Whats surprises me now is that the rotor doesnt have a thread to use a rotor puller on :thumbdown:

I think its going to be an interferance fit but i cant budge it and dont want to damage anything trying to wedge it off etc.

Ideas ladies & gents ?

There are three bolt holes to use Steering wheel type puller on, I would recomend using the best puller you can get your hands on. The flywheels are hard to remove from the tapered fit, Be very carefull not to damage the shaft thread or distort the stub end, I machined a spacer to protect the shaft end. If necessary apply heat to the rotor hub preferably with a heat gun, Also the rotor will jump pretty good when it releases be carfull not to let it drop.

I got a puller from Halfords. It worked but it is a sod of a job. I had to elongate the slots in the puller. Find a good tool shop and spend as much as you can afford. This is a job where things can go horribly wrong.
