CONNECTOR 5338493 - Caterpillar

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 Particulate Filter or Catalytic Converter Muffler. Failure to do so could result in personal injury.
The muffler, catalytic converter/muffler, and diesel 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, catalytic converter/muffler and diesel particulate filter.
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 a DPF. Refer to Operation and Maintenance Manual for the intervals of service hours for cleaning of the DPF.
Connect the engine to the electronic service tool before the 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 DPF to cool until the DPF can be safely removed.
Remove the 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 DPF. Refer to Troubleshooting for problem identification and the disposition of the DPF.
Clean the DPF. Refer to Special Instruction, NEHS1109, "Compact DPF Cleaner" for the cleaning procedure.
Reinstall the 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 DPF volume back to the "Clean State". The resetting will allow the regeneration of the DPF to function properly.
Use the electronic service tool to access the configuration parameters. Select "Service" from the top menu and highlight the "Service Procedures" from the menu in the service tool.
From the "Service Procedures" menu, highlight "DPF Ash Service". Select "Start".
Select "Ash Service Reset" to start the test procedure.
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:
"Filter cleaned and reapplied", a DPF that has been cleaned and reinstalled.
"New filter replacement", a new DPF replacement.
"Remanufactured", a remanufactured DPF replacement.
Once the reset is completed, the "DPF #1 Hours since last ash service" will show zero.
