The shop manual recommends draining the oil from the rear drive unit. However, if you

keep the rear drive unit upright after removal, draining isn’t necessary.

Remove rear bearing retaining bolts on the driveshaft housing. These are the two large

hex bolts located opposite one another on the driveshaft housing just forward of the

rubber boot. Since the bolt threads are covered with threadlock, it is necessary to heat

the bolts with a heat gun (BMW recommends to a maximum temperature of 120C). I

applied heat to each bolt for 4-5 minutes. Remove right bolt with a 12mm hex wrench

socket and a breaker bar (bolt is torqued to 105Nm). Remove the 30mm locknut on the

left bolt and then remove the left bolt. No muscle is necessary since this bolt is only

torqued to 7Nm.

Pull rear drive unit from driveshaft. Remember to keep rear drive upright if you didn’t

drain the oil.

Remove the two front bearing retaining bolts on the driveshaft housing. These bolts are

identical to the ones you just removed, but located opposite one another on the forward

part of the driveshaft housing. Follow same procedure.

Remove the shock absorber while supporting the driveshaft housing.

Pull the driveshaft housing off.

Pull the driveshaft from the transmission spline. Using a large screwdriver for leverage

worked well.

This is a good time to clean and inspect the splines on the driveshaft, rear drive unit,

and the rear of the transmission. Check the U-joints for excessive play. Also, check the

four needle bearings and their races in the driveshaft housing. Be sure that they are

sufficiently greased.

So far so good? Have a sandwich and change the audio tape or CD. Remember: no

Bee Gees or Manilow.

Next you need to remove the transmission in order to be able to clean and lube the

clutch splines. But, unfortunately you have to strip more stuff off of your bike.

Remove the fuel tank. See Jon Diaz’s fuel filter change instructions if you haven’t done

this before.

Remove battery.

Unplug the electrical connector for the air temperature sensor on the air box cover.

Remove air box cover & air intake snorkel.

Remove the four nuts holding down the battery tray.
