Rework Procedure
1. Remove the cooling package. Refer UENR2328, Disassembly and Assembly, "Radiator and Hydraulic Oil Cooler - Removal Procedure".
2. Record the diesel particulate filter serial number prior to installing. The serial number is etched into the diesel particulate filter housing in the location shown in Image1.1.1. It is the lower set of digits. Send the new diesel particulate filter serial number and machine serial number to Rob McHardy (MCHARDY_ROBERT_W).

3. Replace the 389-5370 Diesel Particulate Filter section. Refer to UENR0129, Disassembly and Assembly, "Diesel Particulate Filter - Remove and Install" and "Diesel Particulate Filter - Disassemble".
4. When performing this work, replace the three 389-5373 Gaskets (metal) for the diesel particulate filter section and the 345-3579 Gasket between the turbo flange and the DOC inlet.
5. Ensure the diesel particulate filter is installed with the exhaust flowing in the direction of the arrow that is on the diesel particulate filter. Refer to Image1.2.1.
6. Cover both ends of the diesel particulate filter to ensure the ash and soot remain within the diesel particulate filter. Package the diesel particulate filter according to REHS3827, "Procedure to Handle and Ship Diesel Particulate Filters (DPF) and Catalytic Converter Mufflers (CCM)".
7. Connect Caterpillar Electronic Technician (ET). Version 2012A is acceptable but version 2012B is recommended. Go to Service Tab and select "DPF Soot Load Reset". At the next two screens select the "Reset" button in the bottom left corner.
