SafetyCAUTION: Air to Spring actuator assemblies are under heavy spring load and must be disassembled while using extreme caution. Failure to follow these instruction can result in injury. Any unauthorized changes to the valvemayaffecttheproperfunctionalityoftheactuatorandisnotadvised.

Installation Instructions

General Information

All maintenance and servicing should be performed by a trained technician.

Delivery Status

The drive is in the factory-tested state.

Mounting Guidelines

Installation Space: Determineanddefinetheconnectionaxesbeforemounting. Mounting: Exclude tensile and compressive stress.

Assembly

Actuator should be assembled according to assembly instructions.

Disassembly and Assembly Instructions

Disassembly: Air to Spring

1. Clamp the casing (1) in a vise with aluminum (soft) jaws.2. Unscrew the two lock nuts (23) and remove the valve and bracket assembly (24).

3. CAUTION: If the piston (10) is broken, the spring (15) will assist in pushing the top plate assembly (25) out of the casing (1). To avoid injury, make sure that no one stands in front or behind the actuator.

4.Unscrewthetwoflatheadscrews(4)andremovetheflange(16).

5. Remove the top plate assembly (25) from the casing (1). (To aid in removal, it may be necessary to very carefully blow air into the “R” labeled terminal.

6. Remove the base plate/piston assembly (26) from the casing (1).

7. To remove the piston (10) from the assembly, we recommend using a lathe. Mount the shaft (17) on the lathe using soft chuck jaws and press the tailstock against the top of the piston (10). Compress the spring (15) with the tailstock enough to provide access to one of the axle (7) retaining rings (9).

8. Remove the retaining ring (9) and press the axle (7) through the shaft’s axle bore (A) and piston’s helical track (B).

12. Remove the shaft (17) from the base plate (22). The bushings (18,19) will come out on the shaft.

13. The actuator is now fully disassembled and ready for servicing.

Assembly: Air to Spring

1. Before assembling the actuator be sure to replace and lubricate o-rings (5,6,12,14) and seal (11). Ensure that all parts are cleaned and that no debris is left inside components.

2. Thoroughly grease the inside of the casing (1) and piston (10).

3. Install the bushings (18, 19) on the shaft (17). Replace shaft o-ring (20) and lubricate.

4. Insert the shaft (17) into the base plate (22).

5. We recommend using a lathe to aid in the following assembly steps.6. Mount the shaft (17), with base plate (22) installed, on the lathe using soft chuck jaws and insert the piston (10) into the top of the spring (15). Place the bottom of the spring (15) against the top of the base plate (22) and press the tailstock spindle against the top of the piston (10).

7. Compress the spring (15) with the tailstock until the shaft (17) is inserted into the bore of the piston (10). Continue tensioning the spring until the shaft’s axle bore (A) is aligned with the helical track (B) and is accessible for the installation of the axle assembly.
