Re: R26 Black Phosphate Plating

Get two "bolt geeks" together and see what transpires. Manganese phosphate, right? I am not sure if they used Manganese phosphate on items, its more for wear resistance than simply anti-corrosion if I understand it correctly (correct me please if I am wrong). I believe that for bolts and nuts, they ...

Re: R26 Black Phosphate Plating

Jim, For the R 26 go to the parts manual in our library and you can see the finish listed for the various components. Go to https://vintagebmw.org/library_data/PartsManual_R24_1956_German_Rigid_R25R25-2R25-3R26.pdf And for an example look at page 20 (page 27 of the PDF) at number 61 which is the cla...

A full article, with pictures, is forthcoming in the next issues of Classic BMW Motorrader. The sheer amount of motorcycles on-site was staggering, 1850 motorcycles, w...

Re: Vape conversion (generator only)fuse question

I did exactly what you are doing and I put a fuse in as vape suggests. I would suggest putting the fuse inline.

Re: Side stand and foot peg finish

Bob, I do not own a R 90 S, but I back channeled to the experts and they said the stand was cad plated and the foot pegs were flash chrome. By “flash chrome” I think they mean “Matt chrome” but I am not 100% on that. They also said they use cad (if they can get it) today or silver zinc chromate if t...

Re: What is correct horn for R26?

If you are looking for a 100 point restoration, the owners manual that is available In our Library shows on page 31 of the PDF "Electric Horn Noris HE 6". I googled "Noris HE 6" and found some for sale! They are actually really cool looking! I don't have an R 26, but if I did I wold have one of thos...

Re: R50 rocker bearing shaft replacement

Ken, Two questions will set your path; is there any play in the rockers on the shaft and have you taken them apart to measure them? If they are within spec there is no need to replace them. They are likely fine and if so I would put krytox in there and go on your merry way. I have only found a few s...

Re: Replacing final drive 1959 R60

Sorry, was out of pocket for a while. Any good welder can weld the final drive. Look at this article on the R 68 case repair that will be highlighted in the upcoming issue. I have welded various items. After welding I used a grinder to get it close, then sandpaper to get it perfect, but after the sa...
