Gear Oil on my tire GS650GLX ...Still

[WilliamGLX81]

Hey everybody. I love my 81 gs650gl, but it's leaking gear oil onto my rear tire and it's a real bummer. It's unsafe to ride until I fix it
Anyhow, I got all moved up to my new school.

It didn't leak until I replaced the oil gear oil. Then I noticed oil smearing along the center hub of the rear wheel and also dripping in big blobs directly onto my tire.

I found out the crush washer for the drain hole was missing and replaced that. In the process, I drained the gear oil I had put in and refilled it carefully.

I think I shot oil into the breather system the first time I replaced it. Would that be showing up in a big glob like that?
I can follow the advice I've been given and pump some compressed air through the pumpkin (if I can borrow a compressor). Does it have to be a good seal, or will the air flow pretty easily?
Is there another way to clean it? I need to pull the wheel off and put real 40%(?) moly paste, not 3% grease on the drive splines anyway, so I'll have the tire off.

Happy Rides!

I assume you are talking about the final drive?
Make sure you did not over fill it, if it is over full it will push the excess oil out through the breather.
Over full, it will also run hotter due to the extra drag of too much oil.

Same goes for the primary drive.

Hi,

Yes, an over-full final drive unit will leak. Clean your tires with Simple Green or other non-toxic grease cutter. Rinse well. The GS650G does not have separate gear oil for the secondary gears, they share the crankcase oil.


Thank you for your indulgence,

Thanks for putting me straight on that Cliff, I did not know that the 650 shares the engine oil, my GS1000 has seperate gear oil for the secondary gears, and will not tolerate being filled to the full point, it will spit a bunch out until it is about half inch below, and then live happily there for ever.

Does sound like you overfilled it, it takes about 1/2 qt. fill just to the bottomof the threads of the fill plug. It's not cheap but you might consider replacing the seal # 16 on parts fisch

Hmmmm. Are there any issues with running below full? I could just let an ounce or two out of it and see if that resolves it....

I made sure to not get above the threads when I refilled it. The angle is pretty awkward when filling it on the center stand.........

Hey wait! Do I fill it on the center stand or side stand?? The side stand is there, but the small metal piece that you catch with your foot broke off one day when I was parked on a steeply crowned road. I've been using the center stand at all times. I need to weld or JB weld the piece back on.

Sorry for being unclear - it's the final drive oil that's leaking. The 650 does share its engine oil with all of the trans. Might be nice if it didn't, but everything has pros and cons.

Fill it on the center stand , on a level piece of ground.
just let a bit out, so the level is just half an inch below the threads, no more than that, see if it resolves the problem.
It will not do any harm, ther is still plenty oil in there, as I said, mine prefered to be there, it would throw the rest out if it was filled to the thread, and it was worse if you were riding fast and hard.
Let us know how it goes.
