Repair 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.
