TR4 Electronic Speedometer with a domed glass reading KPH. A gearbox sensor (supplied separately) provides the electronic feed.


Our range of completely new electronic speedometers complements our exchange service by providing an instrument which is reliable, accurate and free from the troubles of speedometer drive cable failure. The faces are as near as is practicable to the original face with the obvious exception of a small rectangular green window in the face where trip and odometer readings are viewed.

The instruments are offered in the range that covers all eventualities from TR2-TR6. The instrument is calibrated via the trip reset button and can therefore be calibrated accurately to suit any car with any speedometer output drive ratio, differential ratio and tyre size. This will be of particular interest to TR owners who have a none-TR gearbox with an inappropriate speedometer drive gear fitted. 

The appropriate sensor we supply screws onto the TR gearbox speedometer drive output and comes with an electrical lead which drives the speedometer. A bolt counting sensor is available too for those who wish to devise their own installation.

Instructions for fitting and calibration are supplied. Calibration is achieved by using the trip reset button to find the appropriate setting which gives infinite flexibility to recalibrate the instrument in the event of changes of tyre, gearbox or differential ratio and is not restricted to available internal gears as is the case with a mechanical instrument  
 
TR's 4-6 with overdrive will find that the signal transmitter sits out slightly beyond the transmission tunnel and is slightly too large to sit within the standard Triumph speedometer cable grommet. Revington TR have manufactured a suitable 'Bulge' from fibreglass to cover the signal transmitter. It is in fact a fibre glass version of the original cover used on TR4A-6 to cover the speedometer cable angle drive. Order part number 809271FG.

The speedometer comes with manufacturers fitting instructions however additions helpful notes specific to a TR installation are to be found in Information sheet IS0061, downloadable by pressing the 'Further Reading' tab above.
