Speedometers 

These speedometers are calibrated for use on the models shown, so long as original wheel and tyre 

dimensions are also used and the original ratio final drive (differential) is fitted. Any variation from 

standard wheel dimensions or final drive ratio will probably - unless you are very careful - change the 

overall gearing of the car and will result in the speedometer requiring recalibration. 

Somerford Mini can offer if necessary, for those customers with a non-standard car, a bespoke 

speedometer recalibration service. For this, we would obviously require from you as much 

information as possible in order to get the calibration correct for your particular set-up. 

Information needed includes the rolling radius of your wheel/tyre combination, final drive ratio 

and the number of teeth on the speedometer pinion, if any of these differ from standard for your 

year and model of car. Please contact us to discuss details. 

Some speedometers are available as outright new purchases. Others are not and in these instances a 

reconditioned unit may be offered, in exchange for your old speedometer assembly. This process is 

dependent on your old speedometer being in a reconditionable state; if it isn’t, or you have no old 

speedometer to exchange, a surcharge will be levied. Remember to remove your voltage stabilizer from 

the back of the old speedometer before exchanging it! Please see our price list or contact us to find 

out whether your speedometer is available new or as a reconditioned exchange item. 

To identify your old speedometer before ordering a replacement, you will find an ‘SN’ number in small 

print on the face of the instrument. This is the original Smiths Instruments part number and is the 

easiest and most accurate way of establishing and ordering your replacement. For academic reference 

or for those who recognise speedometers by BMC/BL/Rover part numbers, we have also included the 

these numbers in brackets in the ‘Remarks’ column. 

By the way, the ‘TPM’ figure also displayed in small print on the face of the speedometer refers to the 

number of turns per mile it is calibrated for. Those of you with a mathematical inclination will be able 

to use this figure to work out whether your speedometer is correct for your tyre/final drive/speedo 

pinion combination; for the rest of us, it’s just nice to know that another speedometer with the same 

TPM figure will work just as effectively in the same car. 

Note that while originally centre mounted instruments had silver faces (very early models) or black faces 

(all other models), we now offer a selection of new original style speedometers, fuel gauges, temperature 

gauges and oil pressure gauges with attractive magnolia coloured faces, for those wishing to dress up 

their Minis with something a little more individual.
