4.2 Loader
Undercarriage
The axial piston pump for the hydraulic drive is driven by the
diesel engine. Pressure hoses for extremely high pressure
connect the axial piston pump with the axial piston engine.
The axial piston engine is flanged to the axle distribution
gear. The torque of the axial piston engine is transmitted
by the cardan shaft to the front and rear axles, both with
planetary gears.
CAUTION
The maximum speed of the axial piston engine is governed
by settings made at the factory. Any adjustment will render
the warranty invalid.
The front axle is equipped with a wet lamella self-locking
differential (locking value 45%).
As standard, the rear axle is delivered without a self-
locking differential. A self-locking differential (locking value
45%) is special equipment.
Tires
The following tires are permitted:
12.5-18
15.5/55 R 18
and 335/80 R 18
All four tires are of equal size. For the travel direction, if
available, see Figure 4-2.
Steering system
The power for the hydrostatic steering system is supplied
via a priority valve from a gear-type pump. With a minimum
of effort on the steering wheel, the oil flow is directed by a
steering unit into the steering cylinder.
Four-wheel and rear-wheel steering can be selected.
Emergency steering
The hydrostatic steering system can also be used in a
limited way if the diesel engine fails. The loader can be
steered using a considerable amount of manual effort.
