Abstract
Agricultural activities depend largely on mechanical equipment and so availability of machines is a key component to guarantee on-schedule operations. In association with a local service provider of this segment, feasibility of predictive maintenance through oil analysis was assessed. Wear particles and contaminants were measured via spectrometry analysis which is one of most important tools for lubricant assessment. Water content and viscosity were also evaluated. Samples were analyzed by a tribology laboratory and results for viscosity, Fe content and contaminant levels were compared to acceptable limits. Results provided information about condition of engine, final reduction gearbox and differential gearbox, which are critical component for tractors. Problems like excessive wear particles and water content revealed root causes like dust contamination, defective seals and leakage in oil intercooler. Costs of repair and inspection due to predictive maintenance were compared to costs that would result from corrective maintenance. Oil analysis permitted considerable maintenance economy compared to parts and services necessary when tractor breaks down. Since unavailability of equipment may also cause loss of profit, product and clients, this predictive method can be considered effective and advantageous for agriculturists. Additionally it also benefits local service provider by selling assistance plans and increasing customer loyalty.
