82 GL1100:Final drive oil leak

Postby happycat » Thu Jul 29, 2010 9:40 pm



I just had my tire replaced and I've got 90weight leaking out of the bottom of my final drive hub. I've looked at the diagram in the manual, but am a little vague about what seal is likely to have gone bad. Any suggestions as to the most likely culprit? Has anybody else had this problem and fixed it? Any advice would be appreciated.
Thanks,
Ed

There are seals in there that can go bad and cause it to leak. Do a search here, I know there was another member who had the same problem, and ended up taking it apart, replacing seals, and fixing the problem.

Did you replace your FD fluid with a synthetic gear oil? In older BMWs I have owned, synthetic oil caused the seals to shrink and leak a bit. This was corrected by going back to a pure dino lubricant.

Did you overfill it? If there's too much oil (i.e. if you filled it while it was on the side stand), it will vent oil out the vent at the top of the final drive, which will leak down the tire like you show in your picture.

The oil should be filled to the bottom of the fill hole when the bike is level on its center stand. Basically just squirt it in there until it starts running out, then put the fill plug bolt back in.

Hi.My FD was leaking.I don't know what oil I inherited but replaced it with EP 90 mineral oil; as per the manual which,rumour has it restores the seals.A week or so later the leak stopped.A month later still no leak.Worth a try and a cheap and easy fix if it works.

I'm having a similar issue with my 81 GL1100 final drive. I opened the fill hole to check the level and gear oil started coming out, which I guess would mean it is overfilled. However, I'm a bit confused because it looks like the leak is from the bottom of the final drive, where there's a little gap (see image) instead of from the top vent. Additionally, I'm not sure how it would have been overfilled since I filled it using the fill hole while the bike was on the center stand. I'm thinking since I have plenty of the 75W-90, I would try draining it and refilling it just to see if I did somehow overfill. Before I go and waste gear oil, though, I wanted to see if that seemed reasonable or if I'm way off on my diagnosis. Thanks.

I went ahead and tried draining and refilling the final drive oil and there is still a leak. I think I'll try the non-synthetic gear oil mentioned earlier to see if that solves it. Is "Millers Oils 5007JC Green Gear Oil 90, GL1 non-additive" a good alternative to the gear oil mentioned in the "How to replace the gear oil in your final drive" article? I found it on amazon at http://www.amazon.com/Millers-Oils-5007 ... ingdocs-20

It would probably work - but for $2 more, you can get the synthetic Valvoline gear oil that pretty much everyone uses, and is known to work very well:

Admin I think he wanted to try the non synthetic as he thought the synthetic may have shrunk the seal. I have no idea how to quote on here LOL. I am challenged with this tech stuff :lol:
Thanks to all who answer and help. It is greatly appreciated!

You're exactly right, sportsfreaked. The gear oil that I put in and that is now leaking is the synthetic Valvoline gear oil mentioned in the how-to article. I was hoping to try a non-synthetic based on

I hope to get away with not having to pull the final drive apart and replacing a seal. I just don't want to put in something that's going to cause damage to the final drive or worse. The Millers Oils is what came up when I searched for EP90 gear oil on Amazon. Does anyone have any experience with it or have a recommended non-synthetic gear oil to try?
