I need to change the output shaft on my 03 GS500e. I am guessing to do this I'll need to take the gearbox apart.
Someone said to me that rather than strip down from the top, I might be able to turn the engine upside down and take it out fro the bottom. The advantage being that I would not need to take the pistons/ crank/ etc, out.
Is this right? Can it be done without stripping down everything?
Thanks,
Jonny

Yep the cases split from the bottom,so no need to do a total strip

what would indicate the output shaft on the way out, mine seems a bit noisey down that area if the chains slack or loose

on the bike i did last year, the shaft was er.... shafted where the front sprocket sits, the splines were gone. Probably because the sprocket had not been mounted correctly at some point. Usually shafts don't wear, it's the bearings that get noisy. And usually the bearings become bad from an overtightened chain.

I went to change the front sprocket and found the splines had worn down and there was movement on the sprocket. A quick trawl through the 'interweb' showed that it is not unusual for this to happen on GS500's for some reason.

i know its an absolute cardinal sin but if the shafts going to need changing in the near future, can i weld the new spocket to it just to keep me on the road till i have the time to pull it all apart

the shaft may become so hot that the seal behind it gets damaged. Other than that it's no problem

One naughty trick we used to do(a long time ago) when selling a bike,was to push needles in and snap them off flush.This took up the slack Would never dream of doing it now.
