HOSE-DISPOSAL 6I1545 - Caterpillar

You must read and understand the warnings and instructions contained in the Safety section of this manual before performing any operation or maintenance procedures.
Under severe or dusty conditions, or where average operating speeds are less than 40 km/h (25 mph), such as inner city garbage compactors, delivery trucks or drill rigs, the maintenance interval should be reduced to 2000 Service Hours or 40 000 km (24,000 Miles), whichever occurs first.
Perform all previous maintenance as outlined in the Maintenance Intervals along with the maintenance requirements of this interval.Valve Lash and Injector Fuel Timing
Check - Adjust
Initial valve lash and Injector Fuel Timing check and/or adjustment on new or rebuilt engines is recommended at the first scheduled oil change interval or 250 Service Hours, whichever occurs first, due to initial wear and seating of valve train components. All subsequent checks and adjustments are to be made at PM Level 2. Be sure to have a qualified mechanic check and/or adjust Injector Fuel Timing. Special tools and training are required.Refer to the Diesel Engine Repair Manual for the complete procedure to perform this maintenance. The correct Fuel Timing specification is given on the Engine Information Plate. Fuel Timing specifications may be different for different engine applications and/or power ratings.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
