Information:
Refer to this Operation and Maintenance Manual, "Maintenance Recommendations" to determine the maintenance interval for a major overhaul.The need for a major overhaul is determined by several factors.
An increase of oil consumption
An increase of crankcase blowby
The total amount of fuel consumption
The service hours of the engine
The wear metal analysis of the lube oil
An increase in the levels of noise and vibrationAn increase of wear metals in the lube oil indicates that the bearings and the surfaces that wear may need to be serviced. An increase in the levels of noise and vibration indicates that rotating parts require service.Note: Oil analysis can indicate a decrease of wear metals in the lube oil. The cylinder liners may be worn so that polishing of the bore occurs. Also, the increased use of lube oil will dilute the wear metals.Monitor the engine as the engine accumulates service hours. Consult your Cat dealer about scheduling a major overhaul.Note: The driven equipment may also require service when the engine is overhauled. Refer to the literature that is provided by the OEM of the driven equipment.A major overhaul includes all the work that is done for the top end overhaul. A major overhaul includes more parts and labor. More parts and labor are required to rebuild the engine completely.For the major overhaul, all the bearings, seals, gaskets, and components that wear are disassembled. The parts are cleaned and inspected. If necessary, the parts are replaced. The crankshaft is measured for wear. The crankshaft may require regrinding. Alternatively, the crankshaft may be replaced with a Cat replacement part.Your Cat dealer can provide these services and components. Your Caterpillar dealer can ensure that the components are operating within the appropriate specifications.Replacement of Components
Replace the following components during the major overhaul:
Camshaft bearings
Connecting rod bearings
Crankshaft seals
Crankshaft thrust washers
Electronic unit injectors
Gear train bushings
Gear train bearings
Main bearings
Piston ringsInspection, Reconditioning, or Exchanging of Components
Inspect the following components according to the instructions that are in Cat reusability publications. Refer to Guidelines for Reusable Parts and Salvage Operations, SEBF8029, "Index of Publications on Reusability or Salvage of Used Parts".Recondition the worn components or exchange the components, if necessary. Your Cat dealer can provide these services and components.
