    Cool spline lube ???

    I am repairing a 2003 R1150RS (7700 mi on odometer) that I purchased as the infamous 'winter project'. So far everything has been repaired I read in numerous places about splines needing to be lubed. So.... are we talking the splines at the rear wheel end of the driveshaft, or the splines at the transmission end of the drive shaft (or both)?
    I have been on the IBMWR site and saw an article for airheads but must have missed any oilhead article. I have a Clymer's manual, but have found that I need to use it as a guidline as they tend to leave out some info.
    I do not trust the dealer in Portland (Or), and refuse to let them touch my bike. Any help will be appreciated. Thanks

    BMW apparently says "no need to lube splines" on oilhead...

    But I am no expert....opinion's vary all over the map....appears that most don't lube...until failure...

    Transmission input shaft splines. This is where the clutch rides.

    The splines of the driveshaft should also be lubed if your there.

    Splines

    Hello,
    I just asked the question to the service manager at BMW Fort Worth this morning.

    It's reply was: "No need to. BMW stopped reccomending spline lubes for all its models after 1998."

    I hope he's right.

    Regards,

    Alberto

    There is no recomended spline lube interval, but they do need periodic lubing. The best indicator of dried out clutch splines is difficulty in downshifting. If your bike stops downshifting smoothly without any throttle input, the splines are very likely dry and wearing quickly. I would not delay the job at this point. Some bikes got lubed better at the factory than others. My GS needed it at 8000 miles.

    most people who are really into working on their bikes say 20-25K, most people who don't wrench never do it. i'm gonna wait till fall, which should be about 35-40K, i've been doing way too much work on the bike lately..........
