Steering - Husqvarna PT26D Workshop Manual

The injection pump pumps fuel at a high pressure to the injectors, which are opened by the pressure and
then spray the fuel into the prechambers, where it is ignited by the compression heat.

Steering

Husqvarna PT 26D is equipped with a hydraulic control system. A pump (8), located on the side of the
engine behind the injection pump, provides the pressure supply.
The pressure is adjusted by a pressure limiting valve in the control unit (4) under the steering wheel.
The control unit (4) is connected directly to the steering wheel and runs the steering cylinder (3), which is
connected between the chassis and the rear axle, in and out.
If the engine stops, it is still possible to steer, but the wheel is heavy to turn.
The hydraulic tank (14) supplies all hydraulic functions on the machine.
