Abstract: The present invention includes a method and system of identifying parts prone to problems. The method includes the steps of establishing a problem threshold, establishing a part type with a problem, determining a problem level with the part type in response to the part type problem level, comparing the problem level with said problem threshold, establishing a production life of the part type, determining if the part type is within a threshold of the production life, identifying the part type as the problem prone part in response to the comparison and the production life determination.

Abstract: In the operation of wood cutting machines such as delimbing machines which use chain saw cutting devices, it is common to either position the lubricating oil reservoir above the chain saw cutting device to create a gravity-fed system or couple a pump apparatus to the chain saw cutting device. Both arrangements may limit the flexibility of placement of the components comprising the lubrication system. The present invention provides a lubrication system for a wood cutting machine in which a receptacle receives lubricating fluid from the reservoir by use of a source of supply pressure within the receptacle. A source of discharge pressure operates on the receptacle to transport the lubrication fluid to the cutting chain device.

Abstract: It is common in the operation of a construction machine to utilize several different functional modes. Some modes may predominately utilize the braking systems of the machine will other modes may predominately utilize the engine to operate the various implements. In either case, supplemental cooling of these systems is often desirable. The present invention provides a cooling system wherein each axle assembly has a cooling system in addition to the conventional cooling system for the engine. All the cooling systems communicate with a common heat exchanger. A pump is provided to circulate oil from the axle assemblies, as well as coolant from the engine through the heat exchanger to reduce the temperature of one of the fluids. A pair of sensors are engaged with the engine and the axles to selective actuate a clutch member to provide driving engagement between the engine and the pump in response to either component reaching a preselected temperature.
