Engine Mounts
Inspect - Check
Caterpillar recommends checking the engine mounts for deterioration and proper bolt torque. This will prevent excessive engine vibration caused from improper mounting. Refer to the chart Torque For Metric Fasteners in the Torque Specifications section of this publication for recommended torque values.Refer to GMC TopKick/Chevrolet Kodiak Service Manual for necessary repair or replacement procedures for engine mounts.Visconic Dampers
Inspect - Check
Inspect the dampers for evidence of dents, cracks or leaks of the fluid. Damage to or failure of the dampers will increase torsional vibrations and result in damage to the crankshaft and other engine components. A failing vibration damper will cause more gear train noise at variable points in the speed range.Refer to the Diesel Engine Repair Manual for the necessary replacement procedure.Turbocharger
Inspect - Check
1. Remove the exhaust outlet piping and inlet piping from the turbocharger.2. Turn the turbine and compressor wheel by hand.3. The assembly should turn freely.4. Inspect the turbine wheel and compressor wheel for contact with the turbocharger housing.5. There should not be any visible signs of contact between the turbine wheel or compressor wheel and the turbocharger housing.6. Visually check for oil leaks. If service is required, refer to PM Level 3 in the Maintenance Section of this publication for turbocharger service options.Cooling System
Clean and Flush
Do not change the coolant until you read and understand the material in the "Cooling System Specifications" section of this publication. This procedure is to be used for normal maintenance of cooling system surfaces to return to "like new" condition.For heavy build-up of scale and deposits, a severe acid type commercial cleaner or mechanical cleaning will be required.
Our recommended intervals for performing maintenance on the cooling system are based on experience and gathered data relative to the performance characteristics of this engine and its components. Performing maintenance on the cooling system is important because the cooling system has a direct effect on the operation and service life of the engine.Improper maintenance can result in a variety of problems that could shorten the engine's service life or result in poor engine performance.When you drain, clean, flush and replace the coolant, small particles, undesirable chemicals, scale and other deposit formations are removed. These deposits reduce the necessary heat transfer characteristics of the cooling system.Failure to clean and change the coolant as recommended will reduce the efficiency of the cooling system and, in some cases, result in an increase in fuel consumption.Total disregard for performing maintenance on the cooling system can eventually cause engine overheating problems that could result in severe damage to the engine and its components.By performing maintenance on the cooling system, spending money on repairs that could have been prevented may be avoided.1. Remove the radiator filler cap slowly and cooling system drain plug to relieve pressure.2. Remove the cooling system drain plugs or open the drain valve and allow the coolant to drain.3. Install the drain plugs or close the drain valve. Fill the system with clean water and a 6 to 10% concentration of cooling
