3.6.2.1. Mechanical Alignment
Mechanical alignment is done to ensure
that the fifth wheel and hydraulic steering
wheels are at the correct angle to each
other. Once done, there is no need to do
it again except for oil change and
malfunction.
3.6.2.1.1. 1.Method – Truck
It is the method in which the steering
center is brought to the reference point
(where the yel-low alignment arrows
match) by the truck. Alignment can be
achieved by following the steps below.
Trailer brakes must be relea-
sed while doing this.
1. In order to align the wheels of the
trailer, steering should be made with the
truck until the reference alignment ar-
rows on the rear of the vehicle match,
making use of the left or right maneuver-
ing movements of the truck.

2. Then, the hydraulic line of the axle
area and the gooseneck area should be
separated from each other with the help
of the arm in the picture in the goose-
neck area. Valves must be placed in the
manual alignment position. In this way,
even if the truck moves, there will be no
oil flow to the axle area and the axles will
not be steered.

3. After the axle area line is separated,
the gooseneck area should be aligned
with the help of the truck.

4.The position of the valve handle on the
hydraulic steering valve block should be
in the driving position.

3.6.2.1.2. 2. Method – Remote Control
/ Control Panel
It is the method in which the steering
center is brought to the reference point
(where the yellow alignment arrows
match) via the remote control or control
panel. It is used in places where the area
where the truck can maneuver is narrow.
By following the steps below, alignment
can be achieved with the help of the
control.
