Service guidance: Complete the pressure-relief procedure and disconnect power before servicing. Clean the pump block thoroughly and inspect the piston rod and cylinder for scoring or wear. Install the upper packing with the raised lip and O-ring facing down. Install the lower packing with the beveled edge facing up. Use the included piston guide tool to insert the piston rod without damaging the packings. Lubricate components as specified in the service manual. Tighten the retainer nut securely and reassemble the pump block to the housing.
