WARNING
DO NOT remove the relief valve cap (24) without reading the instructions below for disassembling the relief valve.
The relief valve contains a powerful compressed spring (29) that may cause injury or death if released suddenly
• WARNING! Relieve all internal fluid and air pressure inside the pump before disassembly.
• WARNING! Take necessary precautions to prevent the pump from rotating while working on the relief
valve.
• WARNING! Fluid may spill out of the pump when the relief valve faceplate (23B) is removed. Take all
necessary precautions to protect yourself, others, and the nearby area from any harm this fluid may
do.
You should have already checked the drawings in Figures 5.4 and 5.5 to find the correct way to position your relief
valve, based on the pump’s direction of shaft rotation and position and the location of the inlet and discharge ports.
If you have not checked, do it now to decide whether or not you should change the position of our relief valve.
If the relief valve position needs to be changed, follow the instructions below and refer to Section 14, PARTS LIST
and the RV STYLE RELIEF VALVE drawing shown in Figure 5.6.
1. Turn off pump and lock out energy source to driver.
2. Close inlet and discharge valves.

case. Remove faceplate.
5. While viewing faceplate (23B) from end with relief valve cap (24), turn faceplate so that orientation of relief
valve cap to pump matches DIRECTION OF ROTATION drawing previously selected from charts in
Figures 5.4 and 5.5.
6. Install two hollow dowel pins (J) on faceplate end of case (19A, B, C, D, E) if they were removed during
disassembly. Place appropriate number of case gaskets (20) on end of case. Align faceplate (23B) on
hollow dowel pins, maintaining proper orientation as determined above. Secure faceplate to case using
