A military vehicle including a chassis, a cab mounted to the chassis and defining a rear wall, an engine mounted to the chassis, a transfer case coupled to the engine and including a driven output providing mechanical power to the military vehicle and a generator output, and an electric machine positioned rearward of the rear wall of the cab and coupled to the generator output of the transfer case and generating electrical power.

A hydraulic system of a work vehicle includes a recirculation valve which may be closed during a warm-up mode of operation so that conditioning hydraulic fluid from a conditioning hydraulic fluid pump flows through a high pressure relief valve to a conditioning hydraulic fluid reservoir and recirculates from the conditioning hydraulic fluid reservoir back to the conditioning hydraulic fluid pump. Subsequent to the warm-up mode of operation, the recirculation valve may be opened so that conditioning hydraulic fluid from the conditioning hydraulic fluid pump flows through a low pressure relief valve to a main hydraulic fluid reservoir.

A machine can include one or more kinematic linkages having pivot joints that are pivotally articulated by associated hydraulic cylinders. To determine the total joint forces applied to the pivot joints, pressure data is obtained from the hydraulic cylinders and converted to cylinder forces. The cylinder forces are analyzed to determine the total joint forces, and the total joint forces are used to calculate wear severity with respect to the pivot joints. The wear severity can be compared to a lubrication trigger value to determine whether to lubricate the pivot joints.
