Grease on rear tire

Postby reb54 » Thu Oct 30, 2014 7:05 pm



Have a 1981 1100 standard and have grease coming from the bottom of the differential. This slings all over my rim (right side) and on the sidewall of the tire. This happens if I travel at highway speeds.
I recently changed the rear tire and cleaned all of the grease from the inside and used the moly 60 paste on the splines. I then pumped 10 good pumps of grease into the zerk fitting for the drive shaft. The grease that is coming back out is the same grease that I pumped into the zerk fitting.
I keep wiping the mess off of the rear rim and tire but am wondering if there is a seal that needs replacing. I can not find any reference to a seal in my manuals. Has anyone else had this problem? Any solutions?

Thanks / Randal

Is it grease or gear oil? My 81 developed a leak from the differential while on the side stand, it will leak from the weep hole on the bottom of the differential if it's gear oil. I ended up replacing the outer ring gear seal, not a big deal..

Thanks for the reply. I originally thought it was gear oil but the color and consistency is grease and the color is black, like the color of the grease pumped in. I have checked the gear oil level just to make sure and it has been fine. I park mine on the center stand and it is only when I get the bike up to speed that the "slinging" occurs.
Do you think 10 pumps of grease is too much for the drive shaft zerk fitting and it will eventually stop?
Besides the mess, I am concerned about the safety of a greasy rear tire.

Between the differential and the swing arm there is a grease seal. If you have grease leaking then that seal needs replacing. Too much grease shouldn't cause your problem.

It depends. If there was already a lot of grease in there, pumping 10 pumps more could easily push the grease past the seal and cause the problem you're seeing. I'd be inclined to pull things off and clean it up a bit, as well as check on the condition of the seals.

Thanks again for the replies! I now have more information to look into my problem.
I have learned a lot from this site, good to be around individuals that appreciate the "older" motorcycles.
