Information:
Until recently, engine maintenance and repair management involved changing the oil when it was convenient and repairing the engine when it was damaged. This seemed to be the accepted way of managing a maintenance operation.However, due to a variety of circumstances, increasing competition have caused users to look for ways to prolong equipment life and lower operating costs so that they could be competitive.To assist Caterpillar engine users in prolonging engine life and reducing operating costs, the
