Section 1: Seal Replacement Instructions
1�1 Before Disassembly, Empty All the Fluid from
the Actuator
1. Empty the uid from the actuator by suspending it over a suitable catch pan, with the open and close ports down. Turn the actuator to the open and close position a few times. Carefully use compressed air to turn the actuator.
2. Leave the actuator in the closed position for disassembly, i.e., the groove on the position shaft has to be parallel to the port surface. See Figure 1.

1. Remove 3/8" plug and pull the yoke out, see Figure 2.
2. Remove the bottom cover with a pin spanner or two dowel pins and a piece of at
stock. Turn the bottom cover counterclockwise to loosen, see Figure 3.

3. Remove the spline shaft, and thrust bearing. The spline shaft can be removed by tapping the position shaft with a nylon hammer. When the thrust bearing is exposed, remove and set parts aside for reassembly. Use utmost caution to keep
all internal parts clean.
4. Make note of the marks on the spline shaft and housing for reassembly purposes, improve them if needed.

10. Should the parts, or seals, need replaced in the crossover valve, remove valve as
shown in Figure 14. The valve seat may not follow while removing the housing and stem. In this case use a small rod in the bore below the seat to assist in pulling the
seat. Seals are called out in the reassembly instructions.

Section 3: Before Reassembly Inspect All Parts
Section 3: Before Reassembly, Inspect All Parts
1. Assembly of the actuator must be carried out in a clean enviroment. Before
assembly, inspect all parts for damage and ensure they are clean. Parts must be free of burrs, nicks and chips. It is essential not to allow any dirt or debris to enter
the reassembled actuator.
2. All seals and parts must be lubricated during assembly, so have on hand some
clean system uid and some standard bearing grease. It may be helpful to lay the O-rings and X-rings in a pan of clean system uid before installing.
NOTE:
This product is only intended for use in large-scale xed installations excluded from the
scope of Directive 2011/65/EU on the restriction of the use of certain hazardous substances in electrical and electronic equipment (RoHS 2).

2. A small rod, inserted in the smaller bore under the seat, will aid in installing the valve
seat. Make sure the seat is not damaged in the process, see Figures 28 and 29.
3. Use a 13mm hex key to turn the stem counterclockwise to loosen so the valve does not hit the seat while installing the valve in the cylinder.

4. Use an open end wrench to tighten the valve housing in the cylinder.
Note:
The stem must be loosened to ensure the valve is not hitting the valve seat during this process.
5. After the valve assembly has been tightened in the cylinder, use a 13mm hex key to turn the stem in the clockwise direction closing the valve. Tighten to 27 in-lbs
(3 Nm). Most Shafer applications require this valve remains closed all the time.

Section 8: Install the Piston in the Actuator
Housing
1. Lubricate the spline on the piston and inside of the cylinder. Place the piston in the
cylinder. Turn the piston clockwise until the spline is in mesh.
2. The piston may be pushed on into the cylinder with use of an installation tool. In the absence of an installation tool, tap the piston with a nylon hammer.
NOTE:
The spline must be in mesh before any force is applied. Use a cylindrical tool (pipe) after the
hammer head will no longer reach the piston.
