steering valve. The correct alignment is illustrated
in Figure 6C-7.
4. Install the upper cover plate (22), see Figure 6C-2.
5. Assemble the seal spacer (21) and seal (20) as
shown in Figure 6C-2.
6. Grease the upper cover plate (22) and install the
assembled seal, backup ring, and seal spacer,
see Figure 6C-2.
NOTE:
If the metering package was disassembled, pro-
ceed with STEP 7. If the metering package was
not disassembled or a new one is being installed,
proceed with STEP 18.
7. Place the drive plate (9) on a flat lint-free surface,
see Figure 6C-3.
8. Place the stator (8) on the drive plate (9) and
insert the rotor (7) into the stator, see Figure 6C-3.
9. Apply a small amount of grease to the drive link
spacer (6) and install in the rotor (Figure 6C-3).
10.Place the commutator (4) on top of the rotor (7)
with the aligning pin holes facing up (Figure 6C-3).
Place a few drops of oil in each recess of the com-
mutator.
NOTE:
Make sure the pins (5) are pressed below the surface
of the commutator (4).
11. Align the five pin (5) holes in the commutator (4)
with the holes in the rotor (7) and install the pins
(5), see Figure 6C-3.
12.Install the commutator ring (3) and commutator
cover (2), flat surface down with ring screw
recesses, stator screw slots, and cover screw
holes aligned. Install eleven socket head cap-
screws (1), see Figure 6C-3.
NOTE:
Do not tighten the capscrews (1).
13.Place the metering ring (15) on a hard flat surface,
see Figure 6C-2.
14.Place the assembled metering package in the
center of metering ring (15) with the commutator
cover down, see Figure 6C-2.
15.Place a 0.007 in (0.18 mm) shim shock, 0.5 in (13
mm) wide by 1.5 in (38 mm) long in three places,
equal distance apart, between the metering ring
and metering package as shown in Figure 6C-6.
16.Tighten the capscrews (1) twice in sequence (as
shown in Figure 6C-6) to 11-13 in-lbs (1.2-1.5 Nm)
torque.
17.Remove the metering package and shims. Place
the drive link (14) large tang into the rotor
(7, Figure 6C-6). Turn the metering package by
hand to make sure there is no binding.
NOTE:
The metering package should rotate inside the
stator. If binding occurs, disassemble the meter-
ing package, correct the cause, and repeat the
assembly process.
18.Place the metering ring (15) on top of the upper
cover plate (23) with the alignment pin holes up.
19.Lubricate and install the thrust bearing spacer (18)
and thrust bearing (19) into the metering ring (15).
20.Place the metering package (17) into the metering
ring (15), engaging the drive slot with the steering
shaft.
21.Install the commutator ring (16) and seal ring (3).
22.Place the isolation manifold (13) on the metering
ring (15) with the alignment pin holes up. Install
the alignment pins (12).
23.Install three 0.5 in springs (10) into the insolation
manifold (13) and install the valve ring (8).
