STEERING VALVE INSPECTION
1. Inspect the springs (7 and 10) for bent, broken, or
distorted coils.
2. Inspect the finished ground surfaces of all the
components.
3. Inspect the slot edges and surface for nicks, scor-
ing, and rounding.
4. Inspect the hex drive (11) for wear.
5. Inspect the isolation manifold (13) for nicks,
scratches, and scoring. A polished wear pattern
due to valve plate rotation is normal.
6. Inspect the drive link (14) for wear and damage.
7. Inspect the thrust bearing (19) for brinelling, spal-
ling, and missing rollers.
8. Discard all seals and seal rings.
9. Inspect the commutator cover (2) and drive plate
(9) for wear and damage. A polished wear pattern
is normal (Figure 6C-4).
10.Inspect the rotor (7) and stator (8) fit
(Figure 6C-5.)
