Introduction
Diesel Particulate Filters (DPF) and Catalytic Converter Mufflers (CCM) are not applicable to all engines. Some engines contain a DPF and a CCM device that were installed as original equipment to meet engine emissions certification requirements. However, some engines may have had the devices installed during a retrofit program for emissions reduction.
Do not perform any procedure in this Special Instruction until you read this information and you understand this information.Procedure for Shipping the Diesel Particulate Filters (DPF)
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.
Place all the used Diesel Particulate Filter (DPF) center sections, regardless of condition, into a 0.152 mm (0.006 inch) thick plastic bag. Make sure that the bag is sealed before placing the DPF into a shipping container. This must be performed in order to contain any constituents from the used DPF during shipping. New replacement diesel particulate filters may come with a 0.152 mm (0.006 inch) plastic bag that can be used for wrapping the used DPF.Procedure for Shipping the Catalytic Converter Mufflers (CCM)
Seal the inlet port and the outlet port on all used Catalytic Converter Mufflers (CCM) with rubber caps or plastic caps. Various sized plastic caps can be ordered from the Cat Shop Supplies and Hand Tools catalog. Reference caps and plugs under the Shop Supplies section. An alternative is to seal the inlet ports and outlet ports with a 0.152 mm (0.006 inch) thick sheet of plastic and 50 mm (2 inch) wide sealing tape with good adhesive properties before shipping. Sealing or capping must be performed in order to contain any constituents from the used CCM during shipping.
