See Table 4-2 on page 22 and Figure 4.3 on page 22 for additional
Orion 3A parts information.
1. With the manifold housing mounted in a vise, turn the vernier shaft (14) clockwise until the piston is
bottomed.
2. Loosen and remove the end cap (13) using a 1-1/4" wrench. At certain points during removal, the end
cap might appear to lock up. If this occurs, rotate the shaft clockwise until the end cap is free to turn.
3. Remove the O-ring (29) from the end cap.
4. Remove the self-sealing screw (36) which acts as the piston key.
5. Extract the piston (15) by partially screwing in the threaded end of the shaft and pulling.
6. Remove the O-ring (32) from the piston groove.
7. To disassemble the end cap/shaft assembly, mount the end cap in the vise.
8. Loosen and remove the locknut (20) using the isolation valve needle housing socket (PN 68509 ) and
socket wrench.
9. Loosen and remove the end bushing (12) using the isolation valve housing socket (PN 68508) and socket
wrench. Remove the shaft (14). Remove the ball bearings (41) from both sides of the shaft flange.
10. Use a small pick or screwdriver to remove the O-ring (27) from the inner groove of the end cap (13).
Also, remove backup retainer (39) from inner groove of the end cap (13).
11. Wash all parts in solvent and blow dry with compressed air.
4.2.5 Orion 3A Manifold, Vernier Control Reassembly
Tools required:
• tube fluorinated Krytox grease (PN 55593)
• 1-1/4" wrench
• screwdriver (flat-blade)
• socket wrench
• isolation valve needle housing socket

(PN 68508)
• isolation valve needle housing socket

(PN 68509)
• torque wrench
Note

See Table 4-2 on page 22 and Figure 4.3 on page 22 for additional
Orion 3A parts information.
1. Coat all new O-rings with fluorinated Krytox grease before installing.
2. Install the small O-ring (27) into the end cap inner groove. Also, install the backup retainer (39) into the
inner groove of the end cap (13).
3. Hold the shaft (14) vertically with the end that goes through the end bushing (12) toward the ceiling.
Place a light coating of grease on the shaft’s threads. Place a thick coating of grease on top of the shaft
bearing surface.
4. Allowing grease to hold the ball bearings in place, slide the end bushing (12) over the top of the shaft and
down to contact the top of the ball bearings.
5. Rotate the shaft assembly 180°, placing the end bushing towards the floor. Be careful not to displace ball
bearings. Place a thick coating of grease on the shaft and bearing surface. Place 16 chrome ball bearings
(41) on the greased surface, allowing grease to hold them in place.
6. Install the shaft (14) with bearings (41) into the end cap.
