4.4.2 SERIES 304 STEERING AXLE
EXPLANATION OF THE STEERING AXLE SERIES NUMBER
4.4.2.1 DESCRIPTION
The rear wheels are steered by means of a double-acting hydraulic cylinder mounted to the steering cylinder
and the two steering knuckles with two track rod links (fixed length). The motion of the steering wheel
activates the steering control valve controlling the oil flow to the steering cylinder.
The axle body is mounted to the frame with shock mounts allowing the axle to swing on uneven ground.
The steering cylinder is mounted on the axle body with dowel pins and four bolts.
The track rod links have covered joint bearings on both ends and they are joined to the piston rod and
steering knuckle with press-in pins and roll pins.
These connecting rods have a fixed length so that the wheel alignment does not have to be adjusted.
