Steering column
The steering column pipe (4) with internal stee-
ring rod (16) is fixed to the base frame (8) with
four retaining screws (9).
The steering movement of the steering wheel is
transferred through the toothed wheel (16) to the
toothed ring (12) and steering head (13).

Steering head and wheel nub motor
The steering head (13) is fixed to the steering
bearing (11) with a castellated nut (10).
Note:
The toothed wheel (16) and the toothed ring
(12) must have a small clearance (0.5-0.8
mm / 0.02-0.03 in). At the full steering angle
(straight ahead ± 90°) the cables (14) must
not be taut and rub against the chassis.
Regularly grease the toothed ring (12) and
toothed wheel (16) (grease type 6.288-000)
in order to minimise wear.
Note:
The steering bearing (11) is tightend with
the castellated nut (10). An incorrect tightend
castellated nut can cause noises and
damage to the bearing.
