Front caster




The caster is measured between a 20° wheel angle to the right and a 20° wheel angle to the left, and varies according to the vehicle level.
Different vehicle levels therefore make it necessary to determine the specified caster value based on a caster table as follows:
Determine level of front axle and level of rear axle using the a electronic inclinometer.
The level value is displayed by the electronic inclinometer in decimal degrees only (Romess value). The details given in mm in the caster table only serve for a better understanding.
The tolerance is ±30'.
Maximum caster difference between left and right is 0° 30'.

Example:
Level at front axle (VA): 9.0° (value on inclinometer)
Level at rear axle (HA): 3.0° (value on inclinometer)
Specified caster value: 5° 36' (determined from the caster table)
