5. Remove the accumulator by sliding out.
6. Loosen the fitting nut at the intensifier end of the long 1/4" diameter tubing section which connects the
solenoid valve to the intensifier. There is no need to remove the tubing.
7. Remove the two clamps and the intensifier.
8. Using a 7/16" wrench, remove the vent port to the Orion 3A manifold vent outlet (1/8" dia.).
9. Loosen and remove the tubing connections located near the bottom of the Orion 3A manifold that go to
both panel output ports.
10. Remove the panel knobs from the pressure (coarse), vernier and vent valves using the .061" hex wrench.
11. Loosen and remove the two panel screws (PN 60837) from the panel front which secures the manifold to
the panel.
12. Remove the five retaining nuts and lock washers which secure the chassis to the panel.
13. Lift the chassis enough to allow the Orion 3A manifold to clear. Then, remove the manifold.
14. Reposition the chassis over the mounting studs and secure with at least two nuts.

Note

See Table 4-2 on page 22 and Figure 4.3 on page 22 for additional
Orion 3A parts information.
1. Secure the manifold by its center portion, in a bench vise, with the valve knobs pointing upward.
2. Using the .061" hex wrench, loosen and remove the knob inserts (4) from the pressure and vent valve
stems.
3. Loosen the 3/4" locknuts (1) on the pressure and vent valve threaded needle housings (10).
4. Using the needle housing socket (PN 65580) and torque wrench, loosen and remove the needle/housing
assembly (10, 1).
5. To disassemble the isolation valves (two inner valves), first remove the valve needle (18) by turning the
gear clockwise.
6. Loosen and remove the valve housings (19) using the isolation valve housing removal socket

(PN 59793) female socket (PN 65581) and torque wrench.
7. Remove the valve stem seats (8) and valve needle seats (9) using the needle-nose pliers.
8. Remove the inner and outer O-rings (28, 27) and back-up rings (31, 30) from the valve stem seats. Wash
all parts in solvent (de-natured alcohol).
9. To remove valve seats (7) from either the pressure (coarse), vent or isolation valves, try blowing
compressed air through the inlet and outlet fittings. If unsuccessful, continue with the following steps.
10. Using the electric hand drill with the No. 43 bit, carefully drill out the seat hole, ensuring that the drill
does not touch the hole in the manifold housing directly beneath the seat.
11. Blow out any chips from the seat area using compressed air.
12. While holding the 4-40 tap steady and perpendicular to the seat, slowly turn until the tap starts to engage
the seat.
13. When the tap has engaged into the seat, use a small hammer and gently knock upward against the tap
handle to extract the seat.
14. After the seat has been removed, blow any remaining chips from the seat area.
