Re: R51/3 - 1952: Which speedometer should I order?

Well I disassembled the device. The internal assembly looks ok, more or less. The strange thing is that when I turn the spindle, the dial only moves when the device is upside down, or tilted to the side. When the dial face is towards me, the rotation of the spindle does not move the dial at all. Any...

Re: R51/3 - 1952: Which speedometer should I order?

Another thing: Since I'm not in a hurry, and I have tools and time, I'll try to disassemble the speedometer and see what the problem is with it (I remember it was moving but frantically, so maybe it's fine and all the problem was with the speedo cable, which is new now). Does anyone have any idea ho...

Re: R51/3 - 1952: Which speedometer should I order?

Found stamping on the device, made by SWF.
Can someone pls explain what they mean?
I'm quiet sure my bike went through some strange changes during its time here in IL.
Already found that the stamping on the main rear gear is 35x8, hence for a R67 serie with s/c...

The solo rear end ratio for r51/3 should be 39.9 and speedo for km should be w.95 and mph 1.52 according to the chart Kurt posted
Hi Tommy,
Shouldn't it be 35:9 for a solo bike?

Re: R51/3 - 1952: Which speedometer should I order?

Evening Kurt, Thank you.
Does it means I need to know the final drive ratio on my bike?
I think that my 51/3 went through a change on that as I discovered when rebuilding my final drive and asking here some question. Is it the number that is stamped on the main big gear?
If so - then I'm in trouble.

Re: Where to locate all the rubber parts of the headlight support brackets?

Came back for update. I found the old rubber pieces inside the steel holes of the brackets, all hardened and painted with a few layers of old black paint. This explains why the new rubber could not be inserted. Gave those bracket holes a good clean and now all is installed and fine. Thank you all ag...
