Repair Costs

Owning & Operating Costs

11

As stated, repair costs are affected by applica- tion, operating conditions, ownership period, maintenance, and age of the equipment.The most significant effects on cost will be those factors affecting major component life.A second significant factor is whether the repair is performed before or after catastrophic failure. Repair before a major component fails can be one-third of an after failure repair with only a moderate sacrifice in life (see graphs). Oil analysis and other diagnostic tools, maintenance inspections and indicators, and operator notes are vital to determine the optimum repair point and thereby achieving lower hourly repair costs. Maintenance practices are significant because they affect component longevity and the percentage of scheduled, before failure repairs.
