Safety Section
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat® products.Dispose of all fluids according to local regulations and mandates.
Illustration 1 g00104545Prevent the machine from movement. Park the machine on a level surface.Attach a "Do Not Operate" warning tag or a similar warning tag to the start switch or to the controls before you service the equipment. These warning tags (Special Instruction, SEHS7332) are available from your Caterpillar dealer.Required Parts
Table 1 contains the parts needed to complete the installation of the new DEF filter.Note: Only one DEF filter group is required per engine. Use Table 2 to determine which filter is the appropriate filter for each DEF header. Illustration 2 shows the location of the DEF header part number.
