Overhaul Information
An overhaul is replacing the major worn components of the engine. An overhaul is a maintenance interval that is planned. The engine is rebuilt with certain rebuilt parts or new parts that replace the worn parts.An overhaul also includes the following maintenance:
Inspection of all the parts that are visible during the disassembly
Replacement of the seals and gaskets that are removed
Cleaning of the internal passages of the engine and the engine blockMost owners will save money by overhauling the engine at the intervals that are recommended in this Operation and Maintenance Manual. Do not wait until the engine exhibits symptoms of excessive wear or failure, as waiting is not less costly to . A planned overhaul before failure may be the best value for the following reasons:
Costly unplanned downtime can be avoided.
Many original parts can be reused according to the guidelines for reusable parts.
The service life of the engine can be extended without the risk of a major catastrophe due to engine failure.
Achieve the best cost/value relationship per hour of extended service life.Overhaul Intervals
Top end overhauls are determined by the projection of exhaust valve stems. Major overhauls are determined by cylinder compression, crankcase blowby, oil consumption, and results of S O S oil analysis.Some other factors that are important for determining the overhaul intervals include the following considerations:
Performance of preventive maintenance
Use of recommended lubricants
Use of recommended coolants
Use of recommended fuels
Proper installation
Operating conditions
Operation within acceptable limits
Engine load
Engine speedNote: To avoid oil problems, engines that are turbocharged and aftercooled must be operated at a minimum of 60 percent of rated load.Generally, engines that are operated at a reduced load and/or speed achieve more service life before an overhaul, when properly adjusted, operated, and maintained.Overhaul Inspection
Refer to the Service Manual for the procedures that are necessary in order to perform the required maintenance on the items that are listed. Consult your Cat dealer for assistance.To determine the reusability publications that are needed to inspect the engine, refer to Guidelines for Reusable Parts and Salvage Operations, SEBF8029, "Index of Publications on Reusability or Salvage of Used Parts".The Guidelines For Reusable Parts and Salvage Operations is part of an established Cat parts reusability program. These guidelines were developed in order to assist Cat dealers and customers reduce costs by avoiding unnecessary expenditures for new parts. If the engine parts comply with the established inspection specifications, the parts can be reused. New parts are not necessary if the old parts can be reused, repaired, or salvaged.If the parts are not within the inspection specifications, the parts should be salvaged, repaired, replaced, or exchanged. The use of out-of-spec parts could result in unscheduled downtime and/or costly repairs. The use of out-of-spec parts can also contribute to increased fuel consumption and reduction of engine efficiency.Your Cat dealer can provide the parts that are needed to rebuild the engine at the least possible cost.Overhaul Programs
An economical way to obtain most of the parts that are needed for overhauls is to use Cat remanufactured parts. Cat remanufactured parts
