    Hey folks,

    Before someone jumps all over me, I did search!

    The patient: 1983 R100RT (with oil cooler in case anyone asks)

    I did an oil change last night. Everything was going good until I put the oil filter in. It's about 1/2" too short in total, and slightly smaller in diameter than the old one. Of course, grease and oil covered hands, I didn't take a picture of the two side by each. I ended up re-installing the old filter, since otherwise I would be bike-less for about a week.

    My first thought was that the dealer sold me the wrong filter. I did some checking, and BMW part 11 42 1 337 570 is the right filter. On the box it had 11 42 1 337 570 and on the filter it also had 11 42 1 337 570. Yet it doesn't fit.:huh

    Anyone else run into this problem?

    You need to do a bit more of that checking.

    Well played sir. I checked your website (after I had a coffee I might add) and I find that I need 11 00 9 056 146.

    So, I've been proven a fool four times.

    1) When I went to the dealer without the proper part number
    2) When I trusted the parts person at said dealer to know what he was talking about
    3) When I tried to do an internet search before coffee
    4) When I posted my stupidity to an internet forum for all to see, additionally before coffee.

    I think I'll either get that part number engraved or tattooed somewhere.... By the way, I wasn't always this stupid.

    Part numbers change, but the main thing is you need the long filter if you have a cooler. And always check that there isn't an old O-ring stuck on the bottom of the pipe.

    Thanks Anton. I always look in the cannister. I even found an O-ring in there once. Glad I caught THAT. Anyway, I'll be picking up the proper filter this weekend. A few days of fresh oil on an old filter won't hut that much. And the filter was in good shape anyway.

    Just as a follow up, the dealer asked for my VIN to do a "vehicle search." According to BMW Canada, my bike takes the short, hinged filter. :huh

    At least they have the right filter in stock.

    I guess the moral of the story is to do the research before and don't count on the manufacturer/dealer knowing what goes in a 30 year old machine.

    Use the MAX BMW online fiche for looking up part numbers. For your RT, that page is:

    http://www.maxbmwmotorcycles.com/fiche/DiagramsMain.aspx?vid=51649&rnd=05012012

    and shows that the oil filter w/ oil cooler is 11 424 1 337 575.

    And if you go back to the "Change Model" page, there is a box where you can enter your bike's VIN to "verify" model #.

    Remember, your bike is likely older than most of these kids in the parts dept...

    The oil filter for a bike with an oil cooler will only have one small o-ring on one end not both and as you learned it is longer because it does not have the extra aluminum cap behind the outer cover..
