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
A Check Engine Indicator or mileage/time intervals indicate when ash cleaning is
required. Use DETROIT Diesel Corporation's authorized DPF cleaning procedure.
Failure to follow this procedure could result in engine and/or aftertreatment
damage, causing degraded vehicle performance including excess fuel consumption
and decreased engine life. Estimated intervals shown are documented in following
section; Refer to section "Preventive Maintenance Intervals".
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. Open the drain at the bottom of the fuel tank every 30,000 miles (50,000
kilometers) to drain off any water and/or sediment.
WARNING: PERSONAL INJURY
To avoid injury from improper use of chemicals, follow the
chemical manufacturer's usage, handling, and disposal
instructions. Observe all manufacturer's cautions.
