Front sprocket nut - SV650.org

7755matt · 21-03-10, 05:01 PM

I had the front sprocket nut come loose on me twice in teh past, on one occasion leading to a rapid loss of oil onto my rear tyre.

To stop it happening again (hopefully) I applied a dollop of Loctite to the threads. I am now suffering the consequences.

I need to get the sprocket off to replace chain and sprockets, but I cant get the bloomin thing off. Ive had a bit of 3x2" wedged in between wheel and swingarm and a 3 foot breaker bar with a bit of tube over the top (about 4' in all) and it will not budge.

Any suggestions? Or will I need to wait for the garage to open tomorrow and borrow the windy gun???

Bit of heat and penetrating oil?

Did you have the locking tab washer? If so, dodn't forget to bend the tab back

I did get the tab washer bit out of the way, although it never seems to make much contact. I'll see if I can find my blow torch later

Make sure the tab is right out of the way, otherwise if a bit of heat and penetrating oil doesn't help, you might need one of those air impact wrenches

Are you sure the thread is handed the way you think it is?

Sv front sprocket nut is normal threaded.

Yes it is normal handed.

Get a fat mate to stand on the back brake and use a longer bar. Or try the rattle gun.
