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.
Monitoring the Exhaust System
Inspect the Exhaust System as follows:
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.
