Introduction
There are three approved processes for performing the required Diesel Particulate Filter (DPF) maintenance on products equipped with a DPF.Do not perform any procedure in this Special Instruction until you have read this entire Special Instruction and you understand this information. Caterpillar does not recommend any equipment or process for cleaning the DPF other than the procedures listed in this Special Instruction.Note: The approved Caterpillar DPF maintenance procedure permits any of the following actions be taken when the DPF needs to be cleaned:
Replacement of the existing DPF with a new Caterpillar DPF
Replacement of the existing DPF with a remanufactured Caterpillar DPF
Replacement of the existing DPF with a similar DPF cleaned by a Caterpillar approved cleaning device.The DPF can be cleaned a maximum of three times or 20,000 total DPF hours.Replacement with a New or a Remanufactured Caterpillar Diesel Particulate Filter (DPF)
Refer to Table 3 for the existing part number of the filter assembly being serviced along with the corresponding new and remanufactured service kits.

Perform a "Manual DPF Regeneration"
Mark the DPF as shown below in Step 4
Perform the "DPF Ash Service" listed below.Replacement of the existing DPF with a similar DPF cleaned by a Caterpillar approved cleaning device
Inorder to maintain emissions documentationit is necessary that only the same part number DPF must be reinstalled. The cleaned DPF must have a remaining service life similar to the DPF being replaced.Inspect the DPF for markings of a previous cleaning. Refer to Illustration 1 for a typical example of cleaning markings.Cleaning the DPF
Follow this cleaning procedure for removal of the ash from a DPF. Refer to the Operation and Maintenance Manual for the intervals of service hours for cleaning of 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.
Refer to Special Instruction, REHS5704, "Testing the Diesel Particulate Filter (DPF) for Cracks and Leaks" in order to perform the crack detection test. Proceed to Step 2 if the DPF passes the crack detection test. Contact the Technical Communicator, if the DPF fails the test.
Connect the engine through the service port to Cat ET before the DPF is removed from the engine. Once the engine is connected to Cat ET, then perform a "DPF Ash Service Regeneration". The test could take up to an hour. Note: Allow the DPF to cool until the DPF can be safely removed.
Remove the DPF from the Clean Emissions Module (CEM).
