is at ambient temperature.
f. Allow the exhaust gas cooler (NRS) to settle in
order for the air that is trapped to escape.
g. Observe the exhaust gas cooler (NRS) for air
bubbles that indicate a leak. If air bubbles are
seen within 3 minutes, this indicates a leak with
the exhaust gas cooler (NRS). Note the location
or the origin of the leak. Record this information.
h. If no bubbles are detected after 3 minutes, the
exhaust gas cooler (NRS) is reusable.
i. Remove the exhaust gas cooler (NRS) from the
water. If the exhaust gas cooler (NRS) does not
leak, the problem may be elsewhere in the
cooling system or the engine. Refer the service
manual in order to check for leakage. If the
exhaust gas cooler (NRS) does leak, the
exhaust gas cooler (NRS) should be replaced.

Diesel Particulate Filter - Clean
Wear goggles, gloves, protective clothing, and a
National Institute for Occupational Safety and
Health (NIOSH) approved P95 or N95 half-face
respirator when handling a used Diesel Particu-
late Filter or Catalytic Converter Muffler. Failure
to do so could result in personal injury.
The muffler, catalytic converter/muffler, and die-
sel particulate filter will become extremely hot
during engine operation. A hot muffler, catalytic
converter/muffler and diesel particulate filter can
cause serious burns. Allow adequate cooling
time before working on or near the muffler, cata-
lytic converter/muffler and diesel particulate
filter.
The wall flow Diesel Particulate Filters (DPF) require
periodic removal of ash that accumulates from
engine oil.
Cleaning Procedure
Follow this cleaning procedure for removal of the ash
from the wall flow DPF. Refer to Operation and
Maintenance Manual for the intervals of service
hours for cleaning of the wall flow DPF.
1. Connect the engine to the electronic service tool
before the wall flow DPF is removed from the
engine. Once the engine is connected to the
electronic service tool, then perform an ash
service test. This test is a manual regeneration.
The test could take an hour.
Note: Allow the wall flow DPF to cool until the wall
flow DPF can be safely removed.
2. Remove the wall flow DPF from the Clean
Emissions Module (CEM). Refer to Disassembly
and Assembly for the correct procedure.
Note: Identify all engine fault codes if black soot is
discovered on the outlet side of the center section on
the wall flow DPF. Refer to Troubleshooting for
problem identification and the disposition of the wall
flow DPF.
3. The wall flow DPF must be cleaned. Contact your
nearest Perkins distributor for assistance.
4. Reinstall the wall flow DPF onto the Clean
Emissions Module (CEM). Refer to Disassembly
and Assembly for the correct procedure.
Reset the Engine Ash Model
The engine ash model must be reset whenever the
filter is cleaned or replaced. Reseting the ash model
places the wall flow DPF volume back to the “Clean
State” . The resetting will allow the regeneration of
the wall flow DPF to function properly.
1. Use the electronic service tool to access the
configuration parameters. Select “Service” from
the top menu and highlight the “Ash Service
Calibration” from the menu in the service tool.
2. Choose the correct replacement type of diesel
particulate filter in the menu that appears. The
types of replacements for the diesel particulate
filter are the following:
• “New filter replacement”
• “Remanufactured filter replacement”
• “Filter cleaned and reapplied”
Note: If a new filter or a remanufactured filter is used,
the new serial number must be programmed into the
electronic service tool.
Note: For the “Filter cleaned and reapplied” option,
use the electronic service tool to perform the “DPF
Ash Cleaning” reset.
Note: For the “New filter replacement” option, use
the electronic service tool to perform the “DPF
Replacement Reset” .
