Basic Adjustment
BASIC ADJUSTMENTThe centering lugs move through a semicircular arc. They should be adjusted in such a way that they come into contact with the rear rims of the guide sleeves and locate centrally in them.
Failing this, the movement of the top must be corrected at the bearing bracket.
Adjustment of the threaded fork upwards produces a longitudinal adjustment forwards, a vertical adjustment downwards and a slight lateral displacement.
The bearing bracket should be centrally located for basic adjustment. Displacement from this position also results in slight longitudinal and lateral displacements.
Both these adjustments affect the movement of the top mechanism and should therefore be carried out with appropriate care. If necessary the opposite side will also have to be adjusted.
A check must also be carried out to ensure that both swivel gears are operating synchronously. A loud running noise on one side during operation is an indication that the drives are out of sync.
As a check, the distance between the point of attachment of the steering arm to the thrust rod and the top frame arm must be the same on both sides of the vehicle.
Failing this, the swivel gear unit screw fastenings must be loosened and the spacings equalized on both sides.
