The camber and pitch angle of the front wheels are adjusted together. Camber adjustment is performed by turning the eccentric bolts in the hinges of the lower transverse arm. The front eccentric mainly influences the camber, the rear cam changes the pitch angle of the steering axis, when measuring camber and pitch, pay attention to the following points:
When adjusting, a diagram must be used as an aid. Without a diagram, the complexity of adjustment work increases.
Before measuring, put the front wheels in the forward direction.
An eccentric washer is installed on the eccentric bolts on the bolt head, the second eccentric washer is fixed in the groove on the threaded end of the bolt.
Loosen the nut when adjusting. When tightening the nut, it is necessary to keep the head of the eccentric bolt from turning. The tightening torque of the fastening nut is 120 Nm.
When adjusting the camber by rotating the eccentric in the positive direction, the longitudinal angle of inclination of the axis of rotation also changes in the positive direction; when adjusting in the negative direction, the pitch angle of the axis of rotation changes in the negative direction. Changing, for example, in the positive direction of the camber by 0°10' by rotating the front eccentric bolt changes the pitch angle in the positive direction by 0°10'. Such permutations occur when changing in the negative direction. A camber change of 0°10' in the positive direction results in a pitch change of 0°30' in the negative direction. A camber shift from 0°10' gives a pitch change of 0°30' in the positive direction.
Optical instruments must be used to measure camber and caster. Only temporarily can small angles be measured with a mechanical instrument.
