'82 GS650GL output shaft oil seal/plug

[Guest]

I've finally tracked down the source of a pesky oil leak. It's this seal on the end of the output shaft. I really don't want to pull and split the engine just to replace this, because there really aren't any other problems. It's part number 09241-47005, #13 on this diagram. https://www.partzilla.com/catalog/suzuki/motorcycle/1982/gs650gl/secondary-drive-gear

I really would doubt that you need to split the cases. You need to get a blind hole seal puller. They cost about $40 bucks. You could make one. Look at the video. If you are good at fabricating stuff, you can make one. You will see that the tab goes right into the part of the seal that is flexible, and eventually leaks, and the lip goes into the outer inside of the seal. The seals usually pop right out, or it goes crooked, and you just work your way around.

That is an amazing tool, and I'll get one for other types of seals, for sure. However, if look at the picture in my post, you'll see that it's a cap, not a ring. Do you think the blind puller will work on that?

That is a cover for the swing arm nut. It should pop off, use something very thin (but dull) and it should pop off, and you would see a nut underneath it. Or I could be completely wrong. Could you post a pic a little further out from the bike?

Definitely not cap on the swingarm. Wish it were. It's on the end of the output shaft, which on these bikes is a pretty unique system connecting the transmission to the shaft drive.

Follow the link below. I believe that is just a cover, and the seal is underneath. You'll see on the diagram. I don't think the cases would have to be split to remove the seal, after looking at the diagram. A blind hole seal puller will pop it right out, and putting it back in, well I assume you know how to do that.
