3.2.7 ORION 2C Manifold, Vernier Control Reassembly
Tools required: tube fluorinated Krytox grease (PN 55593)
1-1/4" wrench
screwdriver (flat-blade)
socket wrench
isolation valve socket (PN 59793)
female socket (PN 65581)
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.
3. Add mylar washers (41) or (42) to each side of shaft (14).
NOTE: Part number and quantity will vary. Washers are used to adjust vertical play in shaft (14). Try one
item (41) on each side to start.
4. Apply a small amount of fluorinated Krytox grease to the shaft threads and install the shaft (14) into the
end cap.
5. Install the end bushing (12) and tighten until snug using the isolation valve socket, female socket, and
wrench.
6. Feel vertical motion of shaft (14). If motion exists add thicker washer at step 3, otherwise continue to
step 7.
7. Install the locknut (20) and tighten until snug using the isolation valve socket, female socket, and
wrench.
8. Install the O-ring (32) in the piston groove and install the piston (15) into the vernier cavity. Ensure that
the piston keyway is facing the hole into which the self-sealing screw is assembled.
9. Install the self-sealing screw (36) and tighten until snug.
10. Apply a thin coat of grease and install the O-ring (29) on the end cap/shaft assembly, install into
manifold and tighten until snug.
3.2.8 ORION 2C Manifold, Valve Seat Installation
Tools required: needle-nose pliers
tube fluorinated Krytox grease (PN 55593)
No. 43 drill
A/R solvent (de-natured alcohol)
hex wrench (.061")
torque wrench
socket wrench
3/4" socket
needle housing socket (PN 65580)
isolation valve socket (PN 59793)
female socket (PN 65581)
NOTE: See Table 3-2 on page 13 and Figure 3-3 on page 15 for additional parts information.
1. Install a new seat (7) by placing it into the seat well with the needle-nose pliers. Ensure that the seat is
centered within the cavity and gently tap it with a blunt end of a drill bit to install.
2. Install the valve needle seat (9) with the smaller diameter end facing outward.
3. Install new O-rings (28, 27) inside and outside of the valve stem seat. Coat all O-rings and back-up rings
(30, 31) with fluorinated Krytox grease before installation. Make sure that the rings are installed in the
proper order.
4. Install the valve stem seat (8) by grasping the small diameter end with the needle-nose pliers and
positioning in the valve cavity, then gently pushing with the blunt end of a drill bit.
5. For the two outer valves, disassemble the valve needle (11) from its housing (10) and check for any burrs
or dirt on the threads which might interfere with smooth operation.
6. Clean both the needle (11) and housing (10) in solvent, dry the parts and apply a small amount of
fluorinated Krytox grease to the needle threads before reassembly.
7. Assemble the needle into the valve housing and turn it until it stops.
8. Reinstall the needle/housing assembly into the valve cavity until finger tight.
