Revision Summary of Changes
01 Title updated. Effectivity and reference added. Changes were made in problem and solution section. Introduction
The problem that is identified below does not have a known permanent solution. Until a permanent solution is known, use the solution that is identified below.Problem
Illustration 1 g06583948
Clogged diesel particulate filter
Reports have been received that the Diesel Particulate Filter (DPF) may clog at less than 300 hours on the machines listed above. The insulation from the Diesel Oxidation Catalyst (DOC) causes clogging of the DPF.These additional related problems may occur:
Diagnostic code 523602-0"Aftertreatment Regeneration Frequency" may occur
Erratic soot levels
Fuel dilution of the oil or poor oil quality at low machine hoursSolution
Do not operate or work on this product unless you have read and understood the instruction and warnings in the relevant Operation and Maintenance Manuals and relevant service literature. Failure to follow the instructions or heed the warnings could result in injury or death. Proper care is your responsibility.
In the event of failure, follow the troubleshooting procedure below:Troubleshooting Procedure
Check the fuel/water separator for water.Note: Water in fuel can cause excessive ash buildup in the DPF.
Check the air filter and replace the air filter if necessary.
Check the engine oil level and look for fuel dilution of engine oil. Replace the engine oil and filter if fuel dilution has occurred.Note: Frequent regeneration may cause fuel dilution of engine oil due to the fuel dosing required for regeneration. A failed injector could also cause fuel dilution of engine oil.
Check the coolant level.
Troubleshoot active diagnostic codes. Refer to Troubleshooting, UENR3390 on how to troubleshoot excessive DPF regeneration.
Complete a parked DPF regeneration to remove soot.
Inspect the differential pressure sensor tubes for damage.
Inspect the differential pressure sensor tubes and sensors for debris.
Bring the engine up to operating temperature and complete a fuel injector cut-out test to test for failed injectors.If the problem exists even after performing the troubleshooting procedure, create a Global Dealer Solution Network (GDSN) Product Health Service Request (SR) with Workgroup / Subsystem of “Base Machine”. Attach any pertinent photos and detailed failure information for the product group. Mention the CPI number 471218 in the CPI field (and /or) the Technical Information Bulletin (TIB) media number (M0121625) in the description prior to submitting to Caterpillar.Additional troubleshooting/documentation may include:
A photo of the DPF and DOC for identification information
An inspection of the face of the DPF for fibrous material
An inspection of engine oil sample
An inspection of the fuel sample if needed based on diagnostic codes
