FEED PUMP SERVICING
A. Disassembly of the Discharge Valve Assemblies:
Tools required: 3/8” Drive Ratchet; 6 mm Hex Socket; O-Ring Pick; Two slotted screwdrivers, Torque Wrench;
Needle Noise Pliers.
1. Only one valve kit is required to repair all of the valves in one pump. The Valve Kit includes new valve O-
Rings, valve seats, valves, and springs.
2. Disconnect all plumbing.
3. Remove the six socket head screws from the manifold. Remove the outer screws first, then the inner
screws.
4. Using a soft mallet, tap the back side of the Discharge Manifold from alternate sides to maintain
alignment and avoid damage to the plungers
5. Grasp the Discharge Manifold from the underside and gradually lift manifold while you pull away from
the Crankcase.
6. The Adapter/Spacers may stay with either the Discharge or Inlet Manifold. By inserting two opposing
screwdrivers between Spacer and manifold, you can easily pry them out of the Discharge Manifold. If
they stay in the Inlet Manifold, gently work them up and down as you pull away from the Inlet Manifold.
7. The Valve Assemblies are in the Discharge Manifold ports and will fall out when manifold is turned over.
A complete valve assembly includes: Retainer, Spring, Valve and Seat.
