Model 51 O-ring, Guide Ring Replacement - Double Acting With/Without Handwheel

- Place the actuators in an upright position for all disassembly or assembly operations.

- Ensure that guide bushing inner surface (32) is not scratched by Piston subassembly screw (31).

- The handwheel must be in the AUTO position.

- Shut off air supply to the actuator, and isolate the process pressure from the valve to prevent plug movement.

- Disconnect air piping from the Top Plate (17), Separator Plate (69), and check for air pressure in the cylinder.

- Remove the Hexagon Nuts (20), Spring Lock Washers (29), and Center Bolts (19).

- For models with Volume Chamber: Remove Top Plate (17), Volume Chamber Tube (70), Separator Plate (69), Cylinder Tube (14), O-rings (21), Guide Ring (16).

- Without Volume Chamber: Remove Top Plate (17), Cylinder Tube (14), O-rings (21), Guide Ring (16).

- Loosen Set Screw (55) in Adapter (54) and unscrew Adapter (54) from Spacer Tube (5).

Model 52 O-ring, Guide Ring Replacement - Air-to-Extend with Handwheel

- The handwheel must be in the AUTO position.

- Shut off air supply to the actuator, and isolate the process pressure from the valve.

- Disconnect air piping from the top plate.

- Remove the Hexagon Nuts (20), Spring Lock Washers (29), and Center Bolts (19).

- Remove the Top Plate (17) and Cylinder Tube (14), carefully avoiding any horizontal misalignment.

- Replace the O-ring (21) on the Top Plate (17) and the O-ring (21) and Guide Ring (16) on the Piston Plate S/A (15) with new parts. Coat the O-rings and Guide Ring with silicone grease (or equivalent). Coat the sliding surface of the Compression Bolt with industrial grease (not silicone grease).

- Replace Cylinder Tube (14), and Top Plate (17) with only axial movement. Coat the inner surface of the Cylinder Tube with silicone grease.

- Ensure the positions of the air connections are correct. Insert the Center Bolts into the holes of the Top Plate and Yoke. Mount the Spring Washers and Nuts and tighten them lightly by hand. Mount the Spring Washers and Nuts to the bottom side of the Yoke by hand. Ensure that the position of Center Bolts (Approximately +25 mm longer than others) for the accessory mounting plate, if equipped, complies with Figure 13.

- Align the holes of the Top Plate with the Yoke so that the Center Bolts are set vertically.
