    I am suspecting that you are on to something. Even though I definitely saw an O-ring in the pic of the above mentioned frame of the R100/7 microfiche, it is not listed below with a part number. Perhaps they used a common pic for the microfiche and simply didn't include any number because the R100/7 didn't actually use it? In any case, it is shown on the R75 fiche as the original poster said he had.

    Just to be clear. You are not an a$$ any more than I am!!

    I think questioning these types of things helps us all learn more - from all sorts of perspectives! Keep up the great work!

    Or maybe the fiche is just wrong. Do you really think they used the O-ring on nearly every other bike with that flywheel but deliberately didn't install it on the R100/7? Do a 'where used' on the O-ring and see if anything clicks.

    Oops! I guess I am not into all those animations. Duhh!

    I, speaking for myself alone, still do (or say) some dumb-a$$ things! Just ignore me when that happens.

    Could be...can't say as I've ever found it wrong when I needed something...who knows. Here's a RealOEM cross-reference search on the part number. Interesting that the R80/7 shows up but not the R100/7.

    Now check the Euro models, or use MAX which includes the Euro models.

    RealOEM lets you search for European models...I've just been putting in specific VINs.

    Max's fiche doesn't let you search by part number...that I can see. So, I used VINs from various model years and distribution (USA and rest of world). I found the issue. If I use a VIN from say 1979, both RealOEM and Max show the o-ring being called out. Anything from say the early 1978 models, like mine built in 9/1977 or even European bikes built in 9/1977, the o-ring is not called out. So does that mean the BMW didn't use it for a while and then decided they needed it later? Sort of like the transmission circlip?? Doesn't sound like an error...sounds like a running design change.

    Here's the part listing from Max's fiche. It says from 9/78.

    Max's does allow you to search by part number in several ways.

    SPECIFIC MODEL:

    Supposing you want to search by Model: Go to that model's microfiche page. Then up at the top, and click on "Parts Catalog" THEN go to the top of new page, and click on "Search" - This will bring you to a screen where the Model number that you were on will automatically be filled in and then you can enter the BMW part number(s). It will then retrieve each fiche drawing that has that part number for that Model.

    =================
    ALL MODELS:

    If you want to search all models at once, follow this procedure (though there may be a better one there somewhere):

    Go to your model number microfiche page (for example R100/7).

    Then go up and pick "Change Model" button which moves you back so you can choose a different model. However, here, don't pick another model, but go and pick "Search" (same screen as the previous example above)

    Now, the "model number" box will be filled in by "All models" - proceed and enter part number(s) and you will be given each fiche page from every model that has that part number.

    Actually the second "all model" method was shown to me by Rusty at Max's. I find this very helpful. For me, I knew a part number of a carb part (not shown on the R100/7 as it was a flat-top carb) and by using the part number on "all models," I was able to find a corresponding part on a different model bike that matched. This carb part issue was due to the fact that BMW messed up somehow (go figure!!) and Rusty said that one had to look for those flat top carb parts in the R75 fiche.

    Hope this helps!

    Wow...is that cumbersome! I did the search at Max's on the specific part and it brings up quite a display that is quite "tall"...I really have to scroll to find anything. I guess that's why I like RealOEM. We each get used to what works...

    I notice that in the final search results, Max's has the fiche screen for each place that the part has. However, if you look, there are a lot of duplicates of the same screens on that results page. This is typical of some search engines, because they "search" from several perspectives, they get returns from each perspective - sometimes the same return may show up in each of the perspectives - thus a single result will or may turn up many times. Better search engines will examine the results and "weed out" duplicates before showing the returns to the viewer.

    I have in the past just scrolled down through the multiple results pretty quickly fixing my eyes on the location of the bike model location (or whatever I am looking for) and look for the characters quickly to see if what I want is there. In the current example, I looked down through the whole listing in just a few seconds (approx. 30) and saw that the R100/7 did not appear at all. Lots of R100S's and RS's if I remember correctly.

    What is the realOEM website address? I want to add it to my "motorcycle" list of favorites.

    MAX isn't very cumbersome, but I think the description was a bit cumbersome. From the fiche home page there's a search option that takes you to the list of diagrams that use that part. Simple as that. You can optionally limit the search to certain vehicles, and pre-load the currently selected vehicle by going Parts Catalog -> Search. That's about it.

    The duplication is often that you see the ECE models as well as the US vehicles, but all duplication is valid. It's a separate use of the part.

    Check the Resources Link...there's a section for on-line fiche. There are others, though not mentioned much, like Bike Bandit? In the end, all of the on-line fiche are (hopefully) last generation data from BMW is the way I understand it...Anton probably knows more. BMW gets new data, the other places get the last version...Max being a dealer might reformat the data for their own use...I have no clue. I just know that when I go to my dealer, they use something that I've never seen on-line.

    There used to be a "bootleg" version of the parts catalog called ETK. I really liked it but the last time I upgraded to Win7, it wouldn't run anymore. I gave up trying to make it work and just began to rely on the internet and found one program that works well for me.

    I have my browser set so that when i go to Max's, I always go to my specific model bike's fiche. So my instructions are from there, - just showing him the two ways I often use search. I never go to "home page" to start anything.

    Bottom line, it's all about the user interface or GUI in the software world. The data behind it all is basically the same. So, it's how the data is presented or accessed. We each find an interface that we like and have figured out how to get around to get what we need. Beyond that, it's all a matter of opinion.
