(d). Check the front wheel caster.
Front wheel caster standard:3.5°±30′
It is designed to keep the directional
stability of the vehicle and offer the feature
of steering return.

5. Adjust the Wheel Camber
(a). After the adjustment of the kingpin caster,
adjust the adjusting cam module of the
lower swing arm front shaft and the lower
arm rear shaft at the same time.
(b). Rotating the same degree in the same
direction ensures that only the wheel
camber is changed while the caster
remains the same. Increase the camber
by rotating them towards the outside of the
frame at the same time and descrese it
by rotating them towards the inside of the
frame simultaneously.
NOTICE:
Each scale of the cam changes the caster for
7'.Turn the adjusting cam for no more than 4.5
scales from the central line.
(c). After adjustment, tighten the retaining nuts.
Torque: 150~190N·m
(d). Check the front wheel camber.
Front wheel camber standard: 12.08°±30'

6. Kingpin Inclination
(a). After the adjustment of the kingpin caster and the wheel camber, the kingpin
inclination will be accurate, so there is no need to adjust.
