SPEEDOMETER MPH TR2-3B EXCHANGE
AVAILABLE This part is available to order
Exchange domed glass TR2-3B Speedometer. We offer this service as an exchange for your old instrument, or we can refurbish your instrument if you prefer. Part number 108192 was in fact Triumph’s part number for a speedometer for use with a 3.7:1 axle ratio and 165/15 tyres, where the speedometer cable turns 1180 times for one mile covered.
We use this number with the suffix 'EX' for all Miles Per Hour TR2-3B exchange speedometers however we do encourage our customers to provide us with a calibration figure so that the instrument can be calibrated as accurately as is possible within the constraints of the mechanical movement, to suit your car. You can find out how to do this HERE.
Please note that our exchange/refurbish service assumes the unit returned is refurbishable and not scrap. Our terms and conditioned can be viewed HERE.
In addition to refurbishing old instruments, we can also provide a complete range of brand new instruments. Within this range we offer electronic speedometers, which are identical in all respects visually when mounted in the car to an original, with the exception of a small green window in the face that provides odometer and trip information. The great advantage of these instruments is that they are easy to calibrate by the user to suit any gearbox output, axle ratio or tyre size. See below for details.
