A. Release the hydraulic system pressure. Refer to Disassembly and Assembly, "Hydraulic System Pressure - Release".
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 assembliesand all tube assemblies. This helps to prevent fluid loss, and this helpsto keep contaminantsfrom entering the system.
NOTICE
Care must be taken to ensure that fluids are containedduring performance of inspection, maintenance, testing, adjusting and repair of the product. Be preparedto collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.
Refer to Special Publication, NENG2500, "Caterpillar Dealer Service Tool Catalog" for toolsand supplies suitable to collect and contain fluids on Caterpillar products.
Dispose of all fluids according to local regulations and mandates.
NOTICE
Keep all parts clean from contaminants.
Contaminationof the hydraulic system with foreign material will reduce the service life of the hydraulic system components.
To prevent contaminants from entering the hydraulic system, always plug or cap the lines, fittings, or hoses as they are disconnected. Cover any disassembled componentsand clean them properly before assembly.
Clean the hydraulic system properly after any major component exchange or especially after a component failure, to remove any contamination.
