1-1/4" open end wrench
screwdriver (flat-blade)
socket wrench
isolation valve needle housing socket (PN 68508)
isolation valve needle housing socket (PN 68509)
NOTE: See Table 4-2 on page 34 and Figure 4-2 on page 35 for additional 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) that 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 34 and Figure 4-2 on page 35 for additional 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 backup retainer (39) in inner
groove of the end cap (13).
3. Hold shaft (14) vertically with end that goes through end bushing (12) toward ceiling. Place light coating
of grease on threads of shaft. Place thick coating of grease on top of shaft bearing surface.
4. Allowing grease to hold ball bearings in place, slide end bushing (12) over top of shaft and down to
contact top of ball bearings.
5. Rotate shaft assembly 180˚, placing end bushing towards the floor. Be careful not to displace ball
bearings. Place thick coating of grease on shaft and bearing surface. Place sixteen chrome ball bearings
(41) on greased surface, allowing grease to hold them in place.
6. Install shaft (14) with bearings (41) into end cap.
