Smiths 140km/h speedo from a mini

Number is 780

Can someone tell me what this may have been out of?

I was reading a post on mini K speedos and would like to know that if a speedo is set to the diff ratio, can you change the calibration of the speedo to suit a different ratio.

If you are referring to the last number on the inner part of speedo face, it represents turns/Km on a KMH speedo.

Over here there was only one set of speedo drive gears used in the gearbox, so the speedo head was changed with each diff ratio.

These KMH speedos came out of big wheel Mokes.
I have 2 Moke ones, one is marked 800 and the other 860.
I'm running the `860' with a Mini K diff, 3.647:1- and it reads pretty spot on by the 5km highway distance marks.

The other one (800) will read OK with a 3.44 diff, yours would not be far out with this diff either.
But for a Mini-K with original diff, I'd try and find an 860. :wink:



note- multiply this number by 1.62 and it will give turns/MILE so you can compare with the older MPH speedos.
