Air Compressor
Inspect/Rebuild or Exchange
Do not disconnect the air line from the air compressor governor without purging the air brake and auxiliary air systems.Failure to purge the air brake and auxiliary air systems before removing the air compressor and/or air lines could cause personal injury.
Inspect the air compressor as instructed by the truck/vehicle manufacturers' instructions or for more information on how to check your air compressor, refer to the Service Manual for this engine.If you decide to inspect your air compressor, be sure to observe the following actions.* Release the air pressure in the air tank until the air pressure is zero.* Visually check for fluid leaks and listen for air leaks.* Remove discharge fittings and inspect compressor discharge port and discharge line for excessive carbon deposits. The discharge line must be cleaned or replaced and the compressor checked more thoroughly if there is excessive carbon build-up in either the discharge line or compressor discharge port.For more information on how to check your air compressor, refer to the Engine Service Manual.
DO NOT store alcohol in the cab. Alcohol is highly flammable and toxic.
In arctic conditions, use alcohol injection to prevent moisture from freezing in the air system.Removal and Installation
Refer to the established procedure in the Service Manual to Remove and Install the Air Compressor, or contact Caterpillar for assistance.Water Pump
Inspect/Replace
* Inspect the water pump for leaks. The water pump seal is lubricated by coolant in the cooling system. It is normal for a small amount of leakage to occur as the engine cools down and parts contract.Check for unusual noise and/or wobbling of the pulley bearings.Removal and Installation
If the assembly should require disassembly, refer to the established procedure in the Service Manual to Remove and Install the Water Pump, or contact Caterpillar for assistance.Fan Drive & Water Pump Belt Tightener Assembly
Inspect/Check Fan Drive
Inspect the fan drive pulley assembly for excessive looseness or wobble. It should be difficult to detect movement of the shaft in the bearing. If the shaft is loose in the bearings, an inspection of the internal components should be made.The bearing end play should be 0.03 to 0.23 mm (.001 to .009 inch). The radial play should be no greater than 0.13 mm (.005 inch).If the assembly should require disassembly, refer to the Service Manual for the procedure.Inspect/Check Water Pump Belt Tightener Assembly
Inspect the belt tightener assembly. Check for unusual noise and/or wobbling of the pulley bearings.If the assembly should require disassembly, refer to the Service Manual for the procedure.Starting Motor
Inspect/Check for Proper Operation
Caterpillar recommends a scheduled inspection/check of your starting motor. Refer to the established procedure for inspection and specifications in the Service Manual, or contact Caterpillar for assistance.Alternator
Inspect/Check
Caterpillar recommends a scheduled inspection/check of your alternator.Refer to the established procedure for inspection and specifications in the Service Manual, or contact Caterpillar for assistance.Turbocharger
Turbocharger bearing failures can cause large quantities of oil to enter the air intake and exhaust systems. Loss of engine lubricant can result in serious engine damage.Minor leakage of a turbocharger housing under extended low idle operation will not cause problems as long as no turbocharger bearing failure occurred.When a turbocharger bearing failure is accompanied by a significant engine performance loss (exhaust smoke or engine speed up at no load), DO NOT continue engine operation until the turbocharger is repaired or replaced.
Inspect/Rebuild or Exchange
An inspection/check of your turbocharger will minimize unscheduled downtime and reduce the chance for potential damage to other engine parts.For example: severe damage to the turbocharger compressor wheel could cause pieces from the compressor wheel to enter the engine cylinder and cause additional damage to the pistons, valves and cylinder heads.Turbocharger components require precision clearances and balancing due to operation at high rotational (torsional) speeds. Severe Service Applications can accelerate component wear and may suggest the need to Inspect/Repair/Replace the cartridge at reduced intervals to ensure maximum reliability and retention of full core value.The following conditions can indicate severe service operation.* Operation above 36 320 kg (80,000 lb) gross vehicle weight (GVW) and other high load factor operation such as off-highway.* Frequent high altitude operation above 1525 M (5,000 ft).* Extended operation at low idle (cab sleeper).* Arctic operation (regular cold starts at temperatures below -18°C [0°F]).* Extending lube and air system maintenance intervals.* Frequent hot shutdowns (minimum cool down periods after high load factor operation).Caterpillar Recommendation
To minimize downtime, Caterpillar recommends the use of a Remanufactured turbocharger. There are two levels of pricing for Remanufactured turbochargers.* The first level is primarily based on damage to the turbocharger before failure.* The second level is primarily based on damage to the turbocharger or engine after failure.If you choose to operate your engine until the turbocharger fails, your repair cost could be as much as ten times the repair before failure cost due to additional turbocharger and engine damage that could have been prevented.Removal and Installation
Refer to the established procedure in the Service Manual to Remove and Install the Turbocharger, or contact Caterpillar for assistance.
