STEERING
6C-10
3. Install a new retaining ring (24) on the shaft (26)
and attach to tube (27).
4. Install the upper cover plate (23).
5. Assemble the seal spacer (22) and seal (20).
6. Grease the upper cover plate (23) and install the
assembled seal, backup ring, and seal spacer.
7. Place the drive plate (9) on a flat lint-free surface.
8. Place the stator (8) on the drive plate (9) and
insert the rotor (7) into the stator.
9. Apply a small amount of grease to the drive link
spacer (6) and install in the rotor.
10.Place the commutator (4) on top of the rotor (7)
with the aligning pin holes facing up. Place a few
drops of oil in each recess of the commutator.
11.Align the five pin (5) holes in the commutator (4)
with the holes in the rotor (7) and install the pins
(5).
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 the eleven socket head cap-
screws (1).
13.Place the metering ring (15) on a hard flat surface,
see Figure 6C-3.
14.Place the assembled metering package (17) in the
center of metering ring (15) with the commutator
cover down, see Figure 6C-3.
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-7.
16.Tighten the capscrews (1) twice in sequence (as
shown in Figure 6C-7) 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-7). Turn the metering package by
hand to make sure there is no binding.
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).
NOTICE
In the following assembly steps, it is important to
align the components for proper operation of the
steering valve. The correct alignment is illustrated in
Figure 6C-8.
NOTICE
If the metering package was disassembled, proceed
with STEP 7. If the metering package was not disas-
sembled or a new one is being installed, proceed
with STEP 18 (Figure 6C-4).
NOTICE
Make sure the pins (5) are pressed below the sur-
face of the commutator (4).
NOTICE
Do not tighten the capscrews (1).
NOTICE
The metering package should rotate inside the sta-
tor. If binding occurs, disassemble the metering
package, correct the cause, and repeat the assem-
bly process.
