Speedometer Head: Description and Operation
Speedometer Head
DESCRIPTION
NOTE: The following information covers only that service on speedometers which can be performed by the average service man. Repairs on the
units themselves are not included as they require special equipment and extreme care when making repairs and adjustments and only an experienced
speedometer mechanic should attempt such servicing.
The speedometer has two main parts: the indicator head and the speedometer drive cable. When the speedometer fails to indicate speed or mileage, the
cable or housing is probably broken.
