front sprocket nut

[Anonymous]

Changing the front/rear sprocket & chain on my '82 GS750TZ. So I don't have to remove the cover before I pick up the parts does anyone know what size socket I need to remove the nut on the front sprocket.
I can't think pitalls, does anyone know of any to be ready for....Mike

If you don't have the right size socket a big crescent usually gets the job done.

I had to admit it, but that's what I use too.

Mines a 1 1/4 socket 1/2 drive

Tip, leave the chain on and the bike in gear just in case the nut is on to tight. This way you can sit on the bike and use the rear brake to keep the sprocket from turning when you are cranking on the nut.

size

I will resort to an adjustable but as a last resort, I hate 'em, didn't say I wouldn't use them though, just as a last resort.
Thanks for the size Jake, I was intendnig to leave it all toether so I could loosen the nut, nothings worse than trying to move a bolt/nut and the piece spinning around....Mike

I think it's actually a 32mm. Which is very close to what Jake said, but our bikes are all metric, so if you're buying a socket, might as well get the metric one.

inch and a quarter fit my 1150. I dont think I could have used an adjustable without losing lots of knuckle skin and blood

thanks all

I fugured it would be metric, 1 1/4" is so close to 32 mm (1.259843) that it may as well be the same, thanks all....Mike

You may find the sprocket nut loose! I have found that a few times, with only the locking unit keeping it from spinning off! 8O

Loose? Crescent wrench? Wow... I wish mine had been that way. I'm still trying to figure out how to break mine loose. Last night I was standing on the rear brake, leaning on the back of the bike, and pulling on the double cheater bar with all my might and STILL couldn't get it to break free. This thing isn't left hand threaded is it?

It is 32mm (at least on my 1100). Mine wasn't loose at all - in fact I can't get the bloody thing off. This weekend I'll be picking up an electric impact wrench especially for this task.
