Title: 650 Bandit
Post by: Andy B on 08 July 2010, 23:33:55
My lads's mate brought his Bandit round this evening to use my garage & tools to replace his drive chain & sprockets (I didn't think there was much wrong with the old bits .... but still  :-/)
He couldn't remove the main drive sprocket .... & neither could I. We roughly assembled the chain again so we could hold it with the chain & a back wheel locked up with the back brake. There was a 4 lug 'thing' bolted to the drive shaft .... there was a sensor of some kind 'looking' at it, but the 32mm nut holding the sprocket didn't want to budge with either my windy gun or 3' breaker bar.
Any one know if we missed anything?

Are you turning the nut the right way, some applications have left hand threads so it keeps them tight when rotating.

Yes, we checked it was a right hand thread, there was just enough thread showing to check.  :y Even if we were going the wrong way, you can normally get a little movement. This was solid. :-?

Don't know if this will help, link to manuals.

Sensor will be for speedo.

Usually left hand thread with a tabbed locking washer holding it on to stop it coming loose, if no tab washer it may have been over applied with lock tight to keep it on,  no experience with that exact model though. :-/

I`ve just had a look on google and bing and come up only instructions on how to remove the sprocket on a v-strom...Hve you seen a locking washer behind the main nut and have flattened it so as to allow the main nut to spin? if not this could well be the problem so i would have look and then do the above and this should allow the nut to spin....I used to use an old flat screwdriver and gently prise it flat and then undo the nut on my old Gsx 400f....Hope this helps....Also you may have to heat the sprocket up to allow the thread locker to break...

thanks for the suggestions lads, but definitely no tab washer - no problems fitting the socket over the nut, there must be a bottle of Loctite on there. We/he gave up & left the original drive sprocket on, there wasn't much wear, but it was a shame having to keep the old drive sprocket when a new chain and final drive spocket on the wheel was fitted.  :(

There was just enoughthread showing to see it's right hand. Sprocket on near side would say that normal right hand thread would self tighten  :y

Risky that, the sprocket will have worn to the old chain.....it wont show much but it will have.

And a worn sprocket is much more likely to throw the chain.

Try warming the nut up a bit (it does not need to be much) to soften any thread lock that might have been used.

Completely agree, but time was also against us too. I'll suggest he brings it back & we can have another go. I just didn't want to break anything by forcing it.  :-?

With all the added weight and associated instability it results in when airborn......

1/4 of a ton GS's are not meant to get air-born.  ;D

A good job because the prop rotation tends to make them turn on their side when airborn

I've not even taken it off-road seriously yet  :-[

For day-day riding its great though, smooth, silent and don't have to fart around at weekends oiling / cleaning a huge chain
