Introduction
Do not perform any procedure in this Special Instruction until you read this information and you understand this information.
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.
Accumulation of Ash in the Diesel Particulate Filters (DPF)
Diesel Particulate Filters (DPF) require periodic removal of ash that accumulates from engine oil.Refer to Table 1 for the recommended ash cleaning intervals.
Table 1
Engine application     Ash cleaning interval    
C7 and C9     150,000 to 175,000 mi.    
C13 and C15     200,000 to 250,000 mi.    Cleaning Procedure
Follow this cleaning procedure for removal of the ash from a DPF. Refer to the Operation and Maintenance Manual in order to obtain the proper mileage intervals and the hour intervals. The mileage intervals and the hour intervals determine when the cleaning is required.
Connect the vehicle to Caterpillar Electronic Technician (ET) before the DPF is removed from the vehicle. Once the vehicle is connected to Cat ET then perform an ash service test. This is a manual regeneration. The test could take an hour.
Remove the DPF from the vehicle. Disassemble the DPF. Refer to the engine Disassembly and Assembly Manual, "Diesel Particulate Filter - Disassemble" for the proper procedure to remove the DPF and disassemble the DPF.Note: Identify all engine fault codes if black soot is discovered on the outlet side of the center section on the DPF. Reference the engine Troubleshooting Manual for problem identification and the disposition of the DPF.
Clean the DPF. Refer to Operation and Maintenance Manual, SEBU8083, "Diesel Particulate Filter - Clean" for the cleaning procedure of C7 and C9 engines. Refer to Operation and Maintenance Manual, SEBU8087, "Diesel Particulate Filter - Clean" for the cleaning procedure of C13 and C15 engines.
