The integrated engine oil and filter system extends service intervals. This combines the oil stabilizing systems Reserve and Centinel with the Eliminator self cleaning oil filter to extend (with oil analysis) the oil change interval to 4000 hours.
The high capacity engine radiators are each cooled by a hydraulically driven fan for superior cooling efficiency.

The power train consists of two main drives. Diesel engines or electric motors can be supplied. Each of the two gearboxes drives four identical pumps which draw hydraulic oil from an unpressurized hydraulic tank. Open circuit hydraulics provide maximum cooling and filtering efficiency.
The four-circuit system features a load-limiting governor with oil delivery summation to the working circuits and incorporates pressure cut-off control. Hydropilot prioritizes hydraulic flow giving smooth hydraulic response, simple hydraulic system layout, and a reduced number of components. The hydraulic system includes six large swing-out vertical air-to-oil hydraulic coolers with temperatureregulated hydraulically driven fans.

Two hydraulically powered Lincoln Single Line automatic lubrication systems are provided as standard, complete with time and volume variable controls. Activity and malfunction events are linked to the Electronic Control System (ECS). The central lubrication and open gear lubricant are supplied by identical pump assemblies from a refillable twin container which has a capacity of 2 x 300 liters (2 x 80 gal.). Replenishment of the containers is through the Wiggins connections in the service center.
