DOWEL 4N0684 - 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.The following maintenance is to be performed at the interval specified in the Maintenance Schedule for the engine being maintained. Before proceeding with this maintenance, perform all previous maintenance requirements.Air Filters
Check Restriction
Never service the air cleaners with the engine running, since this will allow dirt to enter the engine.
Maintain the air cleaner as per the manufacturer's instructions.As the air cleaner element becomes plugged, the difference of air pressure between the inlet side (dirty side) and the engine side (clean side) will increase.The filters should be inspected frequently when restriction reaches 2.5 kPa (10 in H2O) and fuel consumption begins to increase slightly. The Differential Pressure must NOT exceed 8 kPa (30 in H2O) before replacing air filters.If the air cleaner differential pressure exceeds the above values at any time, clean the filter element or install a new air cleaner element.* Clean or replace the elements using the air filter differential pressure gauge as the basis for establishing this maintenance interval.* Keep spare filter elements on hand for replacement.* Inspect the air system for leaks. Make all repairs to leaky air ducts immediately, to avoid dirt and debris from entering the engine. Dirt and debris could be induced into the engine causing damage to the turbocharger and engine components.Replace Air Cleaner Elements
Refer to the air cleaner manufacturer's instructions for replacing paper type air filter elements. If your air cleaner element becomes plugged, the air can split the element filter material. This allows unfiltered air into the engine which would drastically accelerate internal engine wear.Contact your Caterpillar dealer for the correct filter element to fit your engine and application.Cleaning Air Cleaner Elements
Do not clean the filter elements by bumping or tapping them. Engine damage could result.
For more information on air cleaner element cleaning, refer to the OEM manufacturer's reusability requirements for cleaning of air filters.Fuel Tank
Drain water and Sediment
This maintenance should be performed Every Week (or as necessary) to remove water and sediment. Water in the system could freeze, corrode internal parts or cause the fuel system to malfunction.Drain moisture and sediment at each running shop (terminal) inspection.1. Open the drain valve on bottom of tank (if equipped) to drain water and sediment.2. Close the drain valve.Refer to Fuel Specifications and Cold Weather Operation topics in this manual for additional information on fuel tanks and fuel lines.Scheduled Oil Sampling (S O S)
Refer to the information in the Scheduled Oil Sampling section found previously in this publication regarding the description and specifications for acceptable sampling.Obtain Sample
To compliment a good preventive maintenance program, Caterpillar recommends using S O S at regular scheduled intervals to monitor the condition of your engine, the engine oil and to help determine the maintenance requirements of your engine.Normal test results from the oil samples will be used to develop a "baseline" which will be used as a basis for determining the oil change
