Information:
Inspection of Components
Inspect the following components according to the instructions that are in Caterpillar reusability publications. Refer to Guidelines for Reusable Parts and Salvage Operations, SEBF8029, "Index of Publications on Reusability or Salvage of Used Parts".
Camshaft
Crankshaft
Crankshaft vibration damper
Driven equipment (alignment)
Engine control module
Front gear train
Oil screen
Rear gear trainInspect the crankshaft for any of the following conditions:
Deflection
Damage to the journals
Bearing material that has seized to the journalsCheck the journal taper and the profile of the crankshaft journals. Check these components by interpreting the wear patterns on the following components:
Rod bearing
Main bearingsNote: If the crankshaft or the camshaft are removed for any reason, use the magnetic particle inspection process to check for cracks.Replace the crankshaft vibration damper if any of the following conditions occur:
Engine failure due to a broken crankshaft
Excessive wear of the front bearing for the crankshaft
Excessive wear of the gear train that is not caused by a lack of lubricationInspect the gears of the gear train and inspect the gear train bushings for the following conditions:
Worn gear teeth
Unusual fit
Unusual wearIn addition to the inspection of components, inspect the alignment of the driven equipment. See the Application and Installation Guide for the engine or see the literature that is provided by the OEM of the driven equipment.Inspection, Reconditioning, or Exchanging of Components
Inspect the following components according to the instructions that are in Caterpillar 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.

Clean the oil cooler core and the aftercooler core. Then, pressure test both of these cores. For instructions on cleaning the cores, see this Operation and Maintenance Manual, "Aftercooler Core - Inspect/Clean" topic.Clean the oil suction screen. Also, remove side covers to clean the oil sump. For instructions on removal and installation of components, see the Service Manual, "Disassembly and Assembly" module.Obtain a Coolant Analysis
For a conventional heavy-duty antifreeze/coolant solution, check the concentration of supplemental coolant additive (SCA) regularly. The concentration of SCA can be checked with an S O S coolant analysis (Level 1). A more detailed coolant analysis is recommended periodically.For example, considerable deposits are found in the water jacket areas on the external cooling system, but the concentrations of coolant additives were carefully maintained. The water in the coolant probably contained minerals which were deposited on the engine over time.A coolant analysis can be conducted to verify the condition of the water that is being used in the cooling system. A full water analysis may be obtained from the following sources:
Cat dealer
Local water utility company
Agricultural agent
Independent laboratoryCaterpillar recommends an S O S coolant analysis (Level II) which is a comprehensive chemical evaluation of the coolant. This analysis is also a check of the overall condition inside the cooling system. The following services are provided:
Full Level 1 analysis
Identification of the source of metal corrosion and of contaminants
Identification of buildup of the impurities that cause corrosion
Identification of buildup of the impurities that cause scaling
Determination of possible electrolysis within the engine cooling systemA report of the results of the analysis is provided. Maintenance recommendations are based on the results.For more information about S O S coolant analysis, consult your Cat dealer.Overhaul (Major 2)
Refer to this Operation and Maintenance Manual, "Maintenance Recommendations" to determine the maintenance interval for a Major Overhaul 2.The need for a Major Overhaul 2 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 require service. An increase in the levels of noise and vibration indicates that rotating parts require service.Note: Oil analysis may 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.An Overhaul (Major) 2 includes all the work that is done for the top Overhaul (Major) 1 and Intermediate Overhaul. A major overhaul 2 includes more parts and labor. More parts and labor are required to rebuild the engine.For the Major Overhaul 2, 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 Cat dealer can ensure that the components are operating within the appropriate specifications.Inspection of Components
