Here is an interesting one.
No markings at all, not on the front, and not on the back, OR inside.
This speedo was jerky, and making all sorts of noise, like a bad bearing... the car had sat for a long time, over 4 years, before I got it.
I greased the cable, thinking that was the problem, but it didn't help.
I found this post earlier this week, so when I took it apart to fix the speedo (just needed disassembly and lubrication) I looked for the correction factor.
No factor, anywhere.
I am not sure what this speedo is out of, as it is NOT the stock speedo for this car, this speedo was installed when the car was imported, back in 1985, into the US. The mileage was matched with the old speedo when installed. This was done by a company to "Federalize" the car for US regulations.
The speedo is not the stock one, and it is not a 1982 US spec 320i speedo either... not sure WHAT it is, but it isn't marked.
It's also not correct, according to my GPS, it is about 5 miles an hour off, go 50 and you are really going 45, go 80 and you are going about 74, 100 is about 93.5 (smile)
The odometer is off too, but not as badly, it is .1 mile off, every 7.5 miles, or one mile at 75 miles, in other words, go 75 miles and it is reall y 76 miles.... Strange that the Odometer would be incorrect in the OTHER way. Speedo registers TOO FAST, Odo registers TOO SLOW?
strange...

..and with Mile scale:Muke wrote:0,911 = 4,10-differential (315)
0,911 = 4,11-differential (316-1,6, 318)
0,866 = 3,91-differential (316-1,8, 318i, 320/4, 320i-1,8i)
0,808 = 3,64-differential (320i-2,0, 320/6)
0,762 = 3,45-differential (323i)
number: range: model: diff:
1,465 0-120 315,316,318,318A 4,10 or 4,11
1,393 0-120 320(A)/4,316(A)1.8,318i(A),320(A)1.8i 3,91
1,300 0-140 320i(A(US)),320(A)/6 3,64
1,220 0-140 323i 3,45
1,360 0-140 320i(1.8i)US 3,91
1,266 0-140 320iA(1.8i(US)) 3,64
Btw 0,854 is from 520/4 or 520A/4
