NEW ELECTRONIC SPEEDOMETERS

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 below, with correct 120mm diameter cases, 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 gearbox 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. This sensor, part number RTR8558-1 needs to be ordered separately when ordering the speedometer. We can also supply a sensor that counts the Propshaft rotation, for those who prefer not to us the original speedometer output drive.

TR250, 5 and TR6 owners should note that the new cases used for our electronic speedometers do not have provision for the voltage stabiliser to  be attached to the case. We suggest the voltage stabiliser is attached to one of the two studs that are used to clamp the instrument to the dashboard, secured with knurled nuts.
