An oil cooler is disclosed that comprises a base plate including a recessed portion defined by an interior wall and an exterior wall and including an inlet port and an outlet port. The base plate further includes a divider wall positioned in the recessed portion and extending between the exterior wall and the interior wall to separate the inlet port and the outlet port, a plurality of protrusions arranged in the recessed portion to provide a plurality of tortuous flow paths through which oil flows from the inlet port to the outlet port, and a first set of cooling fins formed on a surface of the base plate opposite the recessed portion. A cover plate is attached to the base plate so as to cover the recessed portion and thereby define a cavity to circulate the oil therethrough, the cover plate including a second set of cooling fins formed thereon.

A system is disclosed. The system includes a processing station for processing at least one of a tire and a wheel prior to joining the tire and the wheel for forming a tire-wheel assembly. The processing station includes one of a tire lubricating sub-station and a wheel lubricating sub-station. A lubrication conditioning system is fluidly-coupled to the processing station. The lubrication conditioning system includes: a lubricant reservoir, a lubricant temperature modifier arranged at least proximate to the lubricant reservoir, a lubricant temperature sensor arranged within a cavity formed by the lubricant reservoir and a controller communicatively-coupled to both of the lubricant temperature modifier and the lubricant temperature sensor.

The present invention relates to an exchangeable milling drum box for a ground milling machine, particularly for a road milling machine, a recycler, a stabilizer or a surface miner, with a milling drum rotatably mounted in the exchangeable milling drum box and a transmission, via which the milling drum can be driven, the transmission comprising a lubrication device with a lubricant, and the exchangeable milling drum box comprising a cooling and/or heating device for lubricant. Furthermore, the present invention relates to a ground milling machine having such an exchangeable milling drum box. The present invention also relates to a method for cooling and/or heating lubricant of a transmission of a milling drum mounted rotatably in an exchangeable milling drum box of a ground milling machine, the method comprising the steps: Supplying cooling and/or a heating medium from the ground milling machine to the lubricant located in a lubrication device arranged on the exchangeable milling drum box; cooling and/or heating the lubricant through heat transfer between the coolant and/or heating medium and the lubricant; and discharging the cooling and/or heating medium from the exchangeable milling drum box to the ground milling machine.
