Problem with rear tire removal - 78 gs750

[newrider]

Hi All-

I am trying to remove my rear wheel to have a new tire put on. I am unable to get enough slack on the chain to get it off of the rear sprocket (even with the axle pushed all the way forward). I recently had a mechanic work on the bike, and he put on a 42 tooth sprocket with a new chain (which I think has the clip removal mechanism, but I am unsure hot to get it open).

Any tips or tricks for getting the chain off and/or removing the clip would be greatly appreciated.

Thanks!

As long as you can get enough slack in the chain, you should be able to turn the wheel backwards and just let the chain come off the sprocket. You may need to remove the chain guard. If that doesn't work, then you could remove the chain by dropping the axle. The only thing with this is that you may not be able to replace the wheel once the tire is replaced.

If the new chain has clip-type master link, you could replace the wheel and then put the chain in place with chain "broken". You would just have to be sure to replace the clip on the master link. Once they are removed (the clips) they need to be replaced with a new clip.

The backwards trick did not work. not enough slack I guess. I got the clip off of the chain, but am unable to pop open the link. Do I just put a screwdriver in there and pop it off, or does it need to be done a certain way?

Newrider,

I have a 42 or 43 tooth sprocket on my 78 750 and have no problems getting the tire off. You certainly have to remove the chain guard, but as long as the front of the tire is shoved all the way against the swingarm, it should come right off. The axle has to come out though. Make sure you can suspend your rear caliper with a bungee cord or something and remove the axle completely. Pay attention to which spacers go where so you can reassemble without question.

PS. Pulling the masterlink is unecessary unless someone took a link out of your chain making it too short.

Yeah, I agree should come right off. I took mine off about a week ago to put on new tires and it came right off. The rear is obviously suspended and I think I just kicked the tire in a couple times. That gave 'nuff slack to feed the chain off the sprocket.

Finally, it is done and back on. The chain that the mechanic put on (630-96) is too small for the 42 tooth sprocket. That is why I could not get it off without breaking the master link - next time I will try the whole thing myself with a slighlty larger chain.

Putting the clip back on the master link was a bear. I spent 3 hours trying to get it on yesterday - cursing and screaming after the first hour. Finally, last night I read a post in here about drilling the holes slighlty larger on the plate so it would fit on the link better, and it took all of 3 minutes to drill and get it on this morning. Made sure to tap the plate towards the clip and used blue RTV to seal the clip on........


Thanks for all the great advice and info posted on this site!

Your chain is going to be too short and will wear out quickly. It is also going to put a lot of stress on the countershaft bearing and seal. Get a longer chain or add some links to the chain you have. You will not regret doing this,
