Steering test
Necessary for the measurement of the castor and pivot pin inclination.
Two procedures are available.
- Simplified procedure + / - 10° (recommended) castor and pivot measurement.
- Complete 0°, + 10°, + 20°, -10°, -20°, -0° castor pivot and steering variance at 20°.
IMPORTANT : The brake pedal press must be used.
- The first steering test will set the inspection values the other one will set adjustment values.
Wheel alignment
Alignment at the rear of the vehicle is assessed in relation to a line drawn through the middle of
the axles. The right-hand and left-hand values are different if the angle formed by the vehicle
travel axis is not zero. Alignment at the front of the vehicle is assessed in relation to line of travel
of the rear axle. If the thrust angle is not zero, the right-hand and left-hand values will be different
when the front wheels are centred on a line drawn through the middle of the axles.
Three procedures are available
- adjustment steering centred
- adjustment steering wheel locked
- adjustment wheel by wheel.
