NOTICE
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, "Caterpillar Tools and Shop
Products Guide" for tools and supplies suitable to collect and contain
fluids on Caterpillar products.
Dispose of all fluids according to local regulations and mandates.
Note: Cleanliness is an important factor. Before you begin the disassembly procedure, the exterior
of the components should be thoroughly cleaned. This will help to prevent dirt from entering the
internal mechanism. Precision components can be damaged by contaminants or by dirt. Perform
disassembly procedures on a clean work surface. Keep components covered and protected at all
times.
Note: Put identification marks on all hoses, on all hose assemblies, on all wires, and on all tube
assemblies for installation purposes. Plug all hose assemblies and all tube assemblies. This helps
to prevent fluid loss, and this helps to keep contaminants from entering the system.
1. Remove the work tool. Refer to Operation and Maintenance Manual, "Work Tool Coupler
