Start By:
- Remove the pilot oil accumulator. Refer to Disassembly and Assembly, "Pilot Oil Accumulator (Dead Engine Lower) - Remove and Installl".
Note: Cleanliness is an important factor. Before the disassembly procedure, the exterior of the component should be thoroughly cleaned. This will help to prevent dirt from entering the internal mechanism.
Note: Put identification marks on all lines, on all hoses, on all harness assemblies, and on all tubes for installation purposes. Plug all lines, hoses, and tubes. This helps to prevent fluid loss and this helps to keep contaminants from entering the system.
