A Tachometer Angle Drive Adapter is a mechanical part that connects a tachometer cable to the engine's crankshaft or another rotating part. Its primary function is to transmit the rotational speed of the engine to the tachometer, which displays it as engine RPM on the instrument panel. The angle drive aspect allows for the tachometer cable to connect at a convenient angle, reducing stress on the cable and improving fit.Attributes: • Manufactured to precise specifications and are built for durability, and reliability• Hardened to RKW C30-46 Which increases the impact resistance and wear resistanceApplications:A Tachometer Angle Drive Adapter is used to change the direction of the tachometer cable while transmitting engine speed for accurate RPM readings.
