    1. Check the operation.


      1. Using a speedometer tester (calibrated chassis dynamometer), check the speedometer indication according to the table below.

        Reference: km/h
        Chassis dynamometer indication

        Acceptable range

        Data in ( ) is for reference
        20 km/h (21.0 to 25.0 km/h)
        40 km/h 41.7 to 46.2 km/h
        60 km/h 62.7 to 67.2 km/h
        80 km/h 83.4 to 88.4 km/h
        100 km/h 104.3 to 109.3 km/h
        120 km/h 125.1 to 130.6 km/h
        140 km/h 145.8 to 151.8 km/h
        160 km/h 166.2 to 173.2 km/h

  2. INSPECT TACHOMETER


    1. Connect a tune-up tachometer, and start the engine.

    2. Compare the test results with the tachometer indications.

      DC 13.5 V, at 25°C (77°F):
      Tune-up Tachometer indication (rpm)

      Acceptable range

      Data in ( ) is for reference
