10.3.1.5 Installation of AR Valves
The suction valve must be installed before the discharge valves. The following
reassembly procedure is applicable for both.
1. Select a new valve assembly.
2. Carefully clean the taper in the fluid cylinder and on the valve seat with a
cleaning solution and a clean cloth. Small scratches can be removed with
steel wool or 100 grit emery paper. Remove all dirt, grease, oil, water, or
other contaminants from the surfaces. Do not oil the seats or the seating
surfaces in the fluid cylinder. Confirm that they are dry before installation.
3. Position the valve assembly directly over the mating taper in the fluid cylinder.
4. Let the valve drop into the taper. Check to see that the seat is sitting in the
taper properly and not cocked to one side. If the valve drops straight, it will
seize on the taper. When correctly seated, it cannot be pulled up by hand.
5. Place the small end of the knockout tool, part number P504436 through the
hole in the cage onto the center of the valve body.
6. While applying downward pressure on the tool, strike the end two times with a
hammer to seat the valve. Be very careful not to strike the cage as this will
cause the valve to be damaged and fail.
7. Verify that the valve body moves freely.
8. After the valve is secured in the fluid cylinder, verify the cage is torqued to
30 ft-lbs (40.7 N-m).
