Er...............:confused I know it's something to do with the direction of rotation; makes the sprocket nut get tighter?

And its better to prevent it turning by leaving the chain on and holding the rear brake until the nut is loose. Not abusing the trans by leaving it in gear and trying to remove the nut.

Ah well, from where do I know this?

My TL number two had the sprocket nut SUPER overtightened.
I tried:
- 1/2" 70cm (2ft) breaker bar. no chance
- 3/4" 2m (6ft) breaker bar. Could turn bike upside down, but not get that nut loose.
- air impact wrench
- bigger air impact wrench
- heated nut and the full program again
No chance, couldn't get the sprocket loose with the chain on and the wheel blocked.

Solution was the following. Now don't laught, OK!! It was not me who put this sprocket nut on!

1) Removed swingarm and built a "locking tool" (haha :)) to block the sprocket solid against the frame in the swingarm pivot:


2) Borrowed the biggest impact wrench I could find: 1200Nm electrical impact wrench used in tunnel construction:

(weights at least 5kg)

Tried for about 5min until it became loose.

Conclusion: Block the sprocket solid (it's probably trash after this) and use a really BIG impact wrench.


Greetings

Wasn't it JamnTLR that posted the pic where the end of the output shaft had snapped off and it was the original sprocket from the factory. :dowhat
