Start By:

  1. Remove the implement, steering, pilot and braking vane pump. Refer to Disassembly and Assembly, "Vane Pump (Implement, Steering, Pilot and Braking) - Remove".

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 an identification mark on the outside of the pump for assembly purposes.
