I am dismantling the rear wheel of my the 1911 Scott ready for rebuilding both wheels on new rims. I have managed to remove the locking nut/ring which I eventually discovered was conventional right hand thread. Behind this is the rear sprocket which is carried on a slightly larger diameter thread. On real close inspection it appears also to be right hand threaded which I find difficult to believe as the action of the chain pulling against it would surely cause it to be loosened ? Can anyone condfirm whether the thread on the sprocket itself is right or left handed before I take out a very large hammer at the risk of busting the whole hub?
The threads for the rear sprocket are left hand. The locking ring is right hand as you already found out. I would suggest that you heat the sprocket around the thread area before you start hitting it with a sledgehammer. If Locktite has been used by an earlier owner (as on mine) – heating to at least 150 degrees Celsius will be necessary.
