MountainClimber,

I hope this helps. Also i appologize in advance. i didn't write down the size of socket that is used for drain plug or alan tip socket that is used for fill plug.

This is the sequence that i use.
1 Remove Oil Fill Plug
2 Place funnel under Oil Drain Plug
3 Remove Oil Drain Plug
4 Let oil drain for approx. 15 minutes
5 Re-install Oil Drain Plug with (NEW CRUSH WASHER) 30 N.M. or 22 ft-lbs
6 Fill with Gear Oil (i use 75/140 SYN.) approx. .85-.95 of a quart, just
slightly below the Oil fill hole. You can see the oil level with a flashlight
easily.
7 Re-install Oil Fill Plug with (NEW CRUSH WASHER) 30 N.M. or 22 ft-lbs
8 The CRUSH WASHERS used for the Drain and Fill are different sizes.
The BMW shop didn't tell me what size they were. Just tell them what your
doing. Hope i didn't forget anything, and i hope this helps.



These are the tools that i used to change the tranny fluid.


A piece of thin Alum. for a funnel. The ratchet/socket are on the drain plug.


Self explanatory what's going on here.


The final Torque. (this is the oil fill plug)


Adios

Thanks

Kook,
thanks for the reply. 2 of the pictures loaded and 2 didn't. I know of the side plug on the tranny but where/how do you fill it?

Part of a service tutorial I did a while back:

Next we look at how to change the trans fluid and oil.

Note: I rode the bike and had it warm when I began.


On the GS remove the bash plate.


It takes a 13mm socket, and a 10mm socket. Simply loosen the nuts, and the 10mm bolt, and the plate will fall off.


Always loosen the tranny fill bolt BEFORE draining the trans., If you canít get it out, you donít want the trans empty.

The Allen is a 6mm.


The trans drain takes a 19mm socket. Just loosen and remove the bolt


Neither bolt was a magnetic kind.

Note: My trans fluid looked like new at 23,500 miles.


I used a funnel to keep the oil off the exhaust and center stand.

I let the trans drain for about 10 minute. Then I reinstall the drain plug (torque at 30nm, and filled the trans up with 75W140 synthetic gear oil. I used .8 liters, the spec is .7 to .85, or to the filler hole threads on level ground.

Reinstall the filler bolt and torque to 30nm.

Jim
