Actuator Housing Reassembly

Use the AccuValve Actuator rebuild kit.

2. Install the new O-rings on both ends of the shaft. Make note of the O-ring sizes and their

location.

3. Install the Poly seal ring on the actuator piston with the lip on the seal facing in the right

direction

4. Install the O-ring on the bearing cap

5. After inspecting and cleaning, replace at least: exhaust vent, two O-rings on the Actuator Shaft,

1 lip seal on Piston OD, and all six springs.

NOTE

: The Poly Seal ring should be oriented on the piston so that the lip side of the seal is

facing down toward the air cylinder area of the actuator.

6. Align the Retainer Cap tabs with the slots in the Housing.

7. Place the assembled parts with the Retaining ring in place, into a vise to hold the assembly

together.

8. Tighten the vise until the outer diameter of the cap just aligns with the inner groove on the

housing.

9. Squeeze the retaining ring with the snap ring pliers and insert the ring inside the groove in the

housing body.

10. Release the retaining ring and let the ring snap into the groove.

11. Work the vise in and out slightly to ensure that the retaining ring is, seated securely.

12. Loosen the vise and remove the actuator.
