Hi Me again sorry to take up space :oops: But there are more requests

I see in the parts book there are two different batteries, one for the tea cup type head lamp and one for the saucepan type, the one for the teacup lamp , page 25 part num. 2835 appears to have a regulator and isolation switch on the side, and the nical platted brass wound flexable conduit plugs in the bottom. this is what I appear to have .... the only thing is that although I have the regulator and its box,the battery box to which it was attached has long ago rusted away , does any one have ony info photos or dimentions of this unit.

Also sorry to be a pain I would love some dimentions for the key that goes into the headlamp as its the only way to select the two different globes for "country' and 'city' running also off and on....I havent yet seen any for sale....

Kind regards peter G

I can't help with the battery holder as mine is missing also,along with the regulator. I do have an original key. If you want to PM me with a surface mail address I can send you a drawing. Could you send me the deminsions of the regulator box? Dan

Hi Dan if you look in the Motor cycle Buyers guide by Stefan Knittel on page 18 and 19 look under the seat you will see the voltage regulator box mounted there this looks the same as mine with the brass conduit coming out of the end, im not sure if this one was fitted with a key or not....My box is mounted verticaly on the rear down tube next to the battery. My battery strap is also different in that it goes over the battery in the other direction ...that is from front to rear and has an over centre clip for quick release

Does anyone know what ever happended to this bike I wonder .....would be very nice to get some close up pics of this set up , and to find out wheather there was a junction box anywhere to terminate all the flexable coduits because there is two from my headlamp each containing one wire and a larger one for the horn carring two wires... then a conduit from the regulator to the generator which is clearly visable .....

regards PeterG

I went poking through BMW's historical archives and found a couple pictures that might be of use. Unfortunately, I don't really know what I'm looking at, but maybe you do! Wink

BTW, I kept looking at the top photo, thinking, boy, something is weird about that... And then, while previewing this message with the bottom picture to A/B against, I could see that the head is very different (not to mention the front fender, which looks like it came off an R32). Is that from a Zuendapp K500? I'm amazed that anything else would fit such a strange shape...

good a/b'ing there, darryl. i also noted that the floorboards on the top picture are the later post 1931 version that includes the heel tubecoming out of the rear mounting bolt...making me think that the picture was taken about five years after it was made, sitting in some owners backyard...

maybe.

Interesting following this... Isn't the bottom really a drawing? How much would that come into play trying to compare the two?

sorry kurt, that actually is a photograph! what you're seeing is a serious amount of retouching; bmw tended to do this with all their official production pictures.
just think of it as the 20's version of photoshop!

and dan-there's an original almost untouched R42 in the bmw dealer in san francisco one can use for reference; i know that you're not anywhere near there, but the manager of the motorcycle dept. is usually quite happy to take pictures of details if you write to him. because there's no battery in the bike, you'd get a clear view of the bracket.

Yes, they did, and it's quite frustrating. Didn't they realize that in 60-80 years people would be spending hours looking at these photos trying to determine where the wires and cables went, and what all of the little bits looked like?

If you hunt through the historical archives site, you'll see lots of photos like this:

[img]http://darryl.crafty-fox.com/mcpics/vintage/r12/other%20r12s/00004522_m[1].jpg[/img]

and this:

[img]http://darryl.crafty-fox.com/mcpics/2004/r52/r52%20info/00004770_M[1].jpg[/img]

In both of these cases, the photos were taken with the idea of eliminating the background for use in advertising and also in manuals. I think the top view of the R12 above was intended for the manual, to show where all the controls were.

Darryl.... some great pictures....How do you get to them???

the top pic does seem to have an early fender, probably used up the old stock? notice the flat mounting brackets instead of the round ones from R32 so it seems to be a mix of both....

.Also note the three lugs on the rear carrier what for Tool box perhaps? Early saddlebags Big Grin The foot rest tube could be an attempt by the owner to create a stop for the kick starter as I notice most of the pics that I have , the stop lug is brocken from the foot boards. Now a little more research reveals that the battery in the top photo (which I thought was the one I want) is held in place with three bolts , (according to the parts book) it has no strap over the top. So my Battery carrier is different to any I have yet seen, and yet it appears to be unmolested. Better word than "original"
Wink : And what about the seat on that R12 is that poss a Pagusa???? and indeed it appears to be the very pic that is in my Genuine R17 hand book depicting the controls etc. Page 10 even shows the same seat I often looked at that seat and wondered, now I look a Darryls pic and imagen I can see a Logo where Pagusa would be ...or am I imagening it .... :roll: Darryl we need mor pics mate.

As far as the pictures go, there's no secret to it. Follow this link to the Historical Archives. Once there, you can select English (at the bottom of the page) and start searching.

I will say that the searches that have worked for me have been about the least intuitive ones, but at least the current incarnation of this site is faster than it used to be. I suggest that you not bother with the image search and instead use the advanced, regular search, on Products, and then select the year that you're interested in. This is how I've found most of the images you've seen.

And there are all kinds of tantalizing documents listed too -- but alas, I haven't been able to actually fish one out and read it. I suppose I should try ordering some of them and see what happens...

Archive Search

I have good luck searchng as follows:

Select advanced search.

Select "product"

Searchfield = '"description"

Operator = "contains"

Your Searchterm = insert your year of interest

After you click on "search", you should get a list of Resultlist of bikes, cars, engines, etc.

If you double click on the name of your item of interest, you should get a Dataview of that product. On the right side of the Dataview you can click on items like "the product is shown in the following images." When you do, you will get thumbnail views of the available images. Pointing to a thumbnail will cause a short description to be displayed.

Unfortunately, none of the workshop literature is actually displayed online.

However, I visited the Archives a few years ago armed with a list of R5 workshop literature that I obtained from this website. They were kind enough to hand me several folders of information and access to a copy machine.

The Montage-Anweisungs, or Assembly Instructions, are especially interesting and useful because they document the changes, modifications and fixes for problems.

They are continually adding more photos so it pays to check the Archives every few months.

Happy searching!

Bruce

Sounds like you're doing about the same thing I am. You'd think that: image search -> keyword R42 (for example) would bring everything up, but that finds nothing at all. But persistence pays off.

Perhaps I'll get another chance to visit the archives and get some of the assembly instructions as well, for my R52. Or maybe I'll try to put in an order for it and see what happens.

i've found that i sometimes get more results if i type it this way:

BMW R 42

or:
BMW R/42

it seems to like the spaces between the keywords-sometimes! there's no consistency in it, as though different people at bmw put the keywords in as to their liking.

so much for german engineering!

Say, Peter, you're right! I just dug up my R12 manual (an nth generation photocopy of the English language book) and so far as I can tell, this is the same photo as in the book, with that odd seat, and all the very early bits like the Wallentacho (drum speedometer) and the ignition twist grip. The only difference I can see is that the front brake lever is fully extended in the book, and the lighting seems more even than in this photo. Perhaps this was a test shot.

it might be; pagusa did exist by the mid thirties. it also might be from a company they used at the time call Bruninhous. i've come accross a few original seats-front and pillion-for sale through the years that were from them, though i believe that bmw first went to that style for the R5-officially, that is.

just something else to mess up your search...

I look at pictures in the Archives, Handbuchs and Ersatzteillistes with a bit of skepticism.

In addition to the odd seat, if you look through the Archives' photos, you will discover pictures of some R12/R17 with R11/16 tanks with the speedo in them.

The Ersatzteilliste for the R12/R17 (all the versions that I have seen, at least) shows the R12/R17 tank to have an indentation for the nose of the seat like an R35.

I have no way of knowing if any of those items were ever used in actual R12/R17 production, but they would certainly be rare.

Postwar, BMW is reported to have made mockups for their Handbuchs/Ersatzteilliste photography using configurations that never went into production. It is quite possible they did the same for prewar.

Best regards,

Bruce

You may be in luck, then!

This is a homebuilt airplane with an R63 motor in it!
