Hey guys ill soon be replacing the external seal on the sprocket cover shaft to fix a oil seal. I'm just wondering what parts of the bike have to be removed if I need to replace the internal seal? Cheers

Anyone know?

I guess I am confused by what you are saying... Where exactly is the sprocket cover shaft?  There is a shaft that goes through the sprocket cover, but it doesn't have a seal.

Are you talking about the counter shaft seal?  #32 here: http://images.imagessite.com/OEM_IMAGES/suzuki_mc_images/S89GS500E16.gif  Internal seal being #35?

I don't think you would need to remove anything else, but I have never put my eyes on it.  You should be able to tell when you do the outer seal.

Yeah that's right so it the rod that the gear lever connects to

Wait. What?  Are you now talking about #29 in this diagram? http://www.ronayers.com/GEAR-SHIFTING-C147938.aspx

No its hard to tell from that diagram but when you take the sprocket cover off you have rod that the gear shift lever was connected to which goes into the engine, what you can see is an outer seal and then my understanding is on the other side there is a inner seal.

Here is a picture of it.

Does that picture make it a bit clearer?

Anybody know?

dont know really .. havent done it on my gs ... but have done it on an old Honda XR 350 ... long time ago...

can you clarify a little ... the outer seal you mention ... is the oily greasy donut at base of that shaft in the pic? ... if so ... then according to the diagram of Paulcet .. you have #29 the seal , length of shaft , pinch spring looking thing around shaft, what i call a collet? around shaft then the little plate bit with a hook on the end ....

just thinking about it all ... might this be a error of description or confusing description ... ie .. are you reading in a workshop manual something like "when replacing the outer seal make sure that the inner seal is 'clean/well seated/level/whatever' and check for leaks before continuing" ... so the manual refers to an 'inner seal' which sounds like a SECOND seal .. but what they MEAN is the inner flat surface of the seal that seats into the little 'cup' that the seal sits in .. is properly cleaned out and the seal is seated  properly so no old gunk is there to damage the new seal .. ?? OR .. the inner ring/lip of that seal is in full contact with the clean shaft and not pinched/folded .. so the thing is working properly?

the exploded diagram shows ONE seal on that shaft from gear lever to the hooked plate thingy ... i dont know that they would leave out a seal in the diagram? ... everything else seems to be there?!

I read on here a while ago that there was a inner seal. Yeah the seal that I currently have is the oily one you can see.

Maybe there is only 1 seal which would be good as I can just replace that in my next oil change

Someone said there was an inner/second seal because you confirmed that the seal you intended to replace was the countershaft seal by way of the diagram #32 in a completely different diagram.  But you really want to replace the shifter shaft seal, which is NOT a sprocket cover shaft seal.  Now you see why calling parts by the correct name and answering questions of clarification are so important?

It's probably just excess chain lube dripping out.

+1 to Jack. 
But it was mentioned in his first thread on this subject. So we're assuming he has already ruled that out.

Sorry Paul didn't mean to annoy you

Yeah I have ruled that out

This may be completely irrelevant to the discussion, but I had a bike with this problem once, and it wasn't the seals "going bad" it was the PO had put a plug in the crank case ventilation hose when he put the unipods on the carbs. Not having anywhere to put all the excess pressure, oil began leaking from the darndest places!

Dunno if you might have the same thing, dunno if the GS has the same type of crankcase ventilator, but might be worth a look?
