I must be missing something. Is there only one picture? Or are there two? The one I see looks like the gear oil sample I took from my tranny which tested fine. Here is what it loked like, very similar to the picture the OP put up.



Then again, my computer has some image loading issues sometimes, and I'm probably missing the boat here. Please set me straight.


Ladies, if a man says he'll fix something, he will. There's no sense reminding him every 6 months or so.

Well it's always hard to tell from a picture, but basically what you drain out should be substantially the same color as what you put in (i.e., look like new gear oil.) A noticeably darker color is often the harbinger of a problem.

Oil analysis discussion primarily involving a 96 RT transmission HERE. The anaysis is from Blackstone as I've been using their service for a couple of years.
I'm sure there are factory shops that do excellent work, but Anton Largiader is an independent who can take care of your trans in the least amount of time and well within the cost you would pay a dealer's service shop (not inexpensive no matter how you do it). He's about a 3 hr drive away, in Charlottesville, or will accept the trans shipped in and can ship it back to you. I drove mine down, watched him disassemble it as noted in this transmission thread, and drove back down to pick it up when he was finished. The wait was because my damage was not immediately apparent and a bearing set had to be ordered.

To determine which transmission you have go to the "Anton" link in the reply above. From the page that opens go to "Back to Index" then under "Transmission, Clutch and Final Drive" go to "R1100 Transmission". There you will find out where to locate the serial number of your transmission and from that how to identify which one it is.

I have a riding buddy with an '02 1150RT who had this happen two years/30,000 plus miles ago. His tranny is still running fine. He changed the transmission oil until it cleaned up, and just continued riding. The bearing is lubed by transmission oil now, instead of the original grease.

Mere lubrication of the bearing is not the issue in this case. In the 1100 transmission (subject of the original post) a seal failure in the rear input shaft bearing is usually caused by failure of the bearing itself. If this is what has happened the problem will not go away, and if not repaired eventually a catastrophic failure will result.

BMW changed the design of the input shaft in the 1150 and it doesn't seem to be affected by this particular problem, so whatever happened to your friend's bike is likely a different matter.

Update on my transmission.
Took the trans. up to Anton at Va. Motorrad in Charlotesville for inspection/repair. Once inside it was found that the Input shaft gear had pounded itself into the bearing and broke the bearing seal releasing the bearing lube into the the gear box. That' what caused the discoloration.
And it turns out that this is a good thing. Had the lube not been discolored I wouldn't have known I had a problem as the transmission wasn't showing any other symptoms.
The gear isn't cheap at $240. With bearing and seals and 4 hours labor the bill came to a tad over $600. Less than I expected.
Anton has a small, cluttered shop on the back of his house. He's hoping to expand soon, but with the economy as it is he's waiting to see how things go.
That aside, after watching him work I was very impressed with the attention to detail. The shimming of these trans. is an art unto itself. I will be taking more work to him if needed.
I've enclosed a picture to show what went bad.

Here's another picture of the bad gear and bearing. The previous picture was the new gear (left) and damaged gear.
You can see how the gear impacted the bearing, breaking the seal.
If not repaired the bearing would soon disintegrate causing a lot more damage.
