PROBLEM

Show/hide table

The existing 320D FM Excavator harvester hydraulic control arrangement may provide too much hydraulic flow for the work tool, that might be not completely cooled down, at the oil cooler under warmer external temperatures. In addition, the existing radiator door and engine hood might not provide the necessary airflow for hydraulic oil cooling.

Rework Procedure

Warning:

Please follow safety recommendations when working over the machine.
Personal injury can result from flame cutting or welding on painted areas. The effect of gasses from burned paint is a hazard to the person doing the cutting or welding.
Do not flame cut or weld on painted areas.

Personal injury or death can result from fumes, gases and ultraviolet rays from the weld arc. Welding can cause fumes, burn skin and produce ultraviolet rays. Keep your head out of the fumes. Use ventilation, exhaust at the arc, or both, to keep fumes and gases from your breathing area. Wear eye, ear and body protection before working. Protect yourself and others; read and understand this warning. Fumes and gases can be dangerous to your health. Ultraviolet rays from the weld arc can injure eyes and burn skin. Electric shock can cause death. Read and understand the manufacturer's instructions and your employer's safety practices. Do not touch live electrical parts.
