Oil Leak

[Erich Z]

I have a really small oil leak from the shift lever. Two or three spots of oil all winter long. What needs replaced there to make it stop, and would it be worth it to fix it?

->gear shaft oil seal (part #28 in the picture). it can easily be replaced the next time You overhaul clutch / transmission / crankshaft...

meanwhile, You just have to live with it. It is annoying but will not leak much.

Clutch pushrod seal are also a very common leak (had both on my old 450). I suggest replacing both at the same time.

OK I need to revive this thread. I now have a leak that is coming from the clutch pushrod seal (a large seal that runs between the crankcase centerline that the clutch actuation rod fits in the middle of).

Obviously I'll have to take off the countershaft sprocket and the triangular bracket that fits across the seal, but is anything else required to get that seal out and replaced?

I would be greatly interested in anyone's horror story or procedure on replacing this seal.

BTW, this is on a '85 GS700.

I've never replaced the clutch push rod seal on a GS but I did do it on a Yamaha 650....and it was really easy. If you look at the schematic, you can probably get a pretty good idea what you're in for.:?

I replaced the clutch and shift lever seals on my old 450. Pretty easy job. Work the old seal out with a pick tool or some people shoot a screw into it and pull it out with pliers. Press the new seal in with your fingers – a little non hardening sealer on the outside of the seal makes it slide in easily.

Hope this helps.

Excellent - thanx gentlemen. It's oil change time anyway, so I'll just kill the 2 birds at one time then.

[psyguy]

make sure you have the right tool for pulling those seals or try that trick with the screw
i didnt know of either of those when i did mine and pulling those two seals out with a screwdriver and pliers proved to be a real pita

I fully expect the PITA part of the equation - seems like nothing is ever "easy" on these things. But as long as I know it can be done without cracking the crankcase - I'm good to give it a try.
