Final Drive no longer maintenance free for 2007+ models

It appears that BMW has added a drain plug and are requiring a fluid flush of the rear drive unit at the 600 mile service only.

Quote:
Ongoing monitoring and long-term tests have confirmed thatwearin the final drive can be furtherminimized overthe service life ofthe motorcycle ifthe oil is changed once during the 600 mile service. Consequently, this oil change has been incorporated into the maintenance schedule as of model year 2007.

Long-term tests have found that not all traces of certain substances used in the process of manufacturing the gearset can be removed by subsequent cleaning. The non-metallic residues of these substances are released and bind with the oil while the final drive is being run in. An oil change as part of the 600 mile service flushes these particles out of the assembly before they have the opportunity of affecting bearing wear.

Subsequent oil changes, for example as part of the 12,000 mile inspection, show no practical benefit in this respect.

A new screw for the oil-drain bore has been introduced as of construction status MY2007. A magnet integrated in the screw ensures that metallic particles are separated out of the oil during the running-in period.

Final Drive

And what might us owners of pre-2007 models do to prevent premature bearing wear??

Yes, there is a plug. What I am questioning is, is BMW going to tell us pre 07's to get it changed?

Good question, but in reality, it would appear that you should get it changed (without waiting) and get a plug with a magnet on it if the current one doesn't have one.

My dealer (Omaha) changed my final drive fluid at no charge, when I was in for a tire change.

The access plug is located on the rear side of the final drive. It is in a horizontal position and would need some sort of hypodermic device to remove the fluid. I would imagine if it is that serious BMW will have a procedure for people who do their own maintaince?

It really isn't that bad.

Short version:

You have to take off the paralever arm and (sometimes) brake caliper. you pull the speed sensor out and the drain plug (it looks like a fill plug since it is in the rear at center level.) and then rotate the housing down 90 degrees and drain it out. Then you measure the right amount to replace and fill it through the speed sensor hole. A lot more work than the old style, but really not that bad.

Make sure to use a new o-ring for the speed sensor and new nyloc nut on the paralever arm.
