A wheel end assembly comprises a wheel hub support housing and a wheel hub drive assembly rotatably connected to the wheel hub support housing. The wheel end assembly also includes a hydraulic motor operatively coupled to the wheel hub drive assembly, the hydraulic motor being disposed to deliver a torque to the wheel hub drive assembly. The wheel end assembly further includes a pump, fluidly coupled to the wheel hub drive assembly and the hydraulic motor, the pump being disposed to provide a flow of hydraulic fluid to the wheel hub drive assembly.

A radiator of a cooling system is disposed within an engine compartment, between a rear mounted engine and a cab on a wheeled machine. The remaining components within the engine compartment are arranged such that they are lower in height than the radiator, the engine compartment enclosure generally angling down from the cab rearward. The enclosure includes an air intake that opens into a gap between the enclosure and cab. A fan disposed rearward the radiator may pull cooling air through the air intake and past the radiator.

Cooling system packaging arrangement for a machine

A load sense hydraulic system includes a pilot operated on/off valve disposed within a signal line which communicates a dynamic load sense signal from a steering control valve to a pressure controller of a load sensing pump. Upon actuating a brake valve or applying a brake mechanism, a pressurized fluid signal downstream of a variable flow control orifice in the brake valve is directed to move the on/off valve to its closed position blocking the dynamic load sense signal from a load sense port to the pump controller. This causes the pump controller to stroke the load sensing pump to its high pressure stand-by position so that the brake valve always functions under high pressure operating conditions.
