    1996 R1100RSL shaft/gear oil change torque

    Hi all

    I am set to do a change on the gear oil in my shaft, and the instructions I downloaded are not specific on the torque needed for my moto.
    For the Transmission Gear Oil change it mentions that a torque of 30Nm, but that some R1100 need a torque of 23Nm, which is it?

    Also, under the Rear Wheel Drive Gear Oil change it mentions using 23Nm torque, with no difference for other types of R1100?

    Does anybody know what type of R1100 I have or the torque needed for my moto? and why the different torque anyway?

    thanks for any info on this

    Ken

    BMW used two different types of plugs on the transmission. One with a taper that uses the crush washer (owed torque) and one without the taper that uses a higher torque with no crush washer.

    well, golleeee! and shazam, too.

    thanks for the edumacating, Anton.

    Do you know the correct torque values for each design? Maybe the values I posted are for one of them?

    Here's hoping 17 lb-ft is correct for the one on the left, 'cuz that's what I did Sunday....

    Okay

    It looks like this according to the pictures and information, if I pull off the plug and it is tapered and has a crush washer then I use 23Nm, without a crush washer I use 30Nm. Thanks a lot for that info!
