Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the machine. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids. Refer to Special Publication, NENG2500, "Caterpillar Tools and Shop Products Guide", for tools and supplies suitable to collect and contain fluids in Caterpillar machines. Dispose of fluids according to local regulations and mandates. |
NOTE: Put identification marks on all lines, on all hoses, on all wires and on all tubes for installation purposes. Plug all lines, hoses and tubes. This helps to prevent fluid loss and helps to keep contaminants from entering the system.
NOTE: Cleanliness is an important factor. Before the removal procedure, the exterior of the component should be thoroughly cleaned. This will help to prevent dirt from entering the internal mechanism.
NOTE: Perform Step 1 to machines equipped with the optional Autodig system.
