Both the poppet and the seat of the relief valves were inspected. Further investigation revealed that the real problem was the relief valves. The relief valves (there are four in the pump) were popping where they shouldn’t be popping, but also jammed where they shouldn’t be. They became the main suspect in what was causing the loss of pressure in the hydrostatic pump.

The pump itself only required repairs, and did not need to be replaced. The hydrostatic pump required a new seal kit, a set of piston shoes, and a relief valve assembly.

The Sundstrand hydrostatic pump was not providing the required pressure because of damaged (and malfunctioning) relief values. The required repairs were made and the pump was sent back to its owner.
