(7) Hold drive assembly (15) into position and place the piston assembly onto the inner and outer springs being
careful not to let the drive assembly (15) move inside the cylinder (4).
(8) Align the vertical groove of the piston (23) with the mark on the outside of the cylinder (4) indicating the
centerline of bearings (19) and place the entire actuator assembly into a press while carefully maintaining the
alignment of the drive assembly (15), cylinder (4), and piston assembly (6).
j. Place mounting adapter (2) onto the top of the piston assembly (6) aligning mounting adapter with both marks
made on the cylinder (4) during disassembly.
k. Place a sleeve around rising stem (1) so that all pressure from the press will be applied to the surface of the
mounting adapter (2).
Internal parts of the actuator can be damaged if excessive force is used to install parts.
Mounting adapter should be slowly pressed into actuator cylinder with minimal force. If
the force needed to press adapter mounting into cylinder seems great, slowly release
press and check that all internal parts are properly aligned with the grooves of the piston.
I. Slowly press the mounting adapter (2) inside the actuator cylinder (4) far enough to install the split wire retaining
ring (5) and then install the split wire retaining ring.
m. Slowly release the press.
Misalignment of coupler (3) will cause possible failure to actuator. Be sure to align coupler with
match mark on cylinder (4).
n. Install coupler (3) and spring pin (14) onto actuator cylinder (4).
