MAN — Monitoring the Fuel and Fuel Tank

Routine Preventive Maintenance Monitoring the Air Cleaner Replace dry-type air cleaner elements when the maximum allowable air intake restriction has been reached. 1. Check the air cleaner restriction gauge (filter minder) daily. 2. Check the gaskets for deterioration and replace, if necessary. 3. Inspect the entire air system for leaks daily. Look especially for torn air inlet piping or boots and loose or damaged clamps. Have worn or damaged parts repaired or replaced. Retighten loose connections. Inspect the Exhaust System as follows: Monitoring the Exhaust System 1. Check the exhaust manifold retaining bolts and other connections for tightness. 2.

Check the exhaust pipe rain cap for proper operation, if so equipped. Monitoring the Aftertreatment System NOTE: All Detroit™ Aftertreatment System (ATS) - equipped engines will illuminate a dashboard warning lamp indicating the need for ash cleaning. Periodically the accumulated ash derived from the engine's lubricating oil needs to be removed from the ATS. This ash does not oxidize in the filter during the regeneration process and must be removed through a cleaning procedure. Inspection of the Air Compressor The air compressor incorporates three of the major systems of a diesel engine (air, lubrication, and cooling). Inspect the air compressor looking for air, oil, and coolant leaks.

Monitoring the Fuel and Fuel Tank To prevent fuel and fuel tank problems, the following measures are recommended: 1. Keep the fuel tank filled to reduce condensation. 2. Before adding fuel, Refer to section "How to Select Diesel Fuel" 3. Refill the tank at the end of each day's operation to prevent condensation from contaminating the fuel. Condensation formed in a partially filled tank promotes the growth of microorganisms that can clog fuel filters and restrict fuel flow. 4. To prevent microbe growth, add a biocide to the fuel tank or primary fuel supply only as needed. 76 All information subject to change without notice.
