3-14. STEERING GEAR MAINTENANCE (CONT)
CLEANING, INSPECTION AND REPAIR (SHEET 1 OF 2)
Dry cleaning solvent P-D-680 used to clean parts is toxic and flammable.
Wear protective goggles and gloves and use only in a well ventilated
area. Avoid contact with skin, eyes and clothes and don-t breathe
vapors. Do not use near open flame or excessive heat and don't smoke
when using it. Failure to do so could cause serious injury. If you be-
come dizzy while using cleaning solvent, get fresh air and medical
attention immediately. If contact with skin or clothes is made, flush
with large amounts of water.
If contact with eyes is made, wash eyes
with water and get medical aid immediately.
Clean all parts using cleaning solvent P-D-680.
.
a.
Put parts on clean surface
and allow to air dry; don’t use cloths to dry parts.
NOTE
If valve spool (28), sleeve (30), or housing (41) are damaged or worn, a
new steering gear valve must be installed. These parts are not available
separately.
b.
Inspect all machined surfaces for scratches, grooves, or other damage.
c. Put rotor (21) in stator (22).
Using thickness gage as shown,
measure clearance between rotor
and stator. If clearance is more
than 0.005 inch, replace rotor
and stator.
d.
Inspect end cap (15), stator
(22), rotor (21), spacer plate
(18), and housing (41) for
cracks, distortion, scoring, or
damaged threads. Replace part if
any of these conditions are
seen.
e.
Check for rough areas on ends of stator (22), rotor (21), machined surfaces
of housing (41), end cap (15), and spacer plate (18). Smooth rough areas
using 600 grit abrasive cloth. Put abrasive cloth on a flat surface that is
as flat as a piece of glass. If abrasive cloth is new, move a piece of steel
across abrasive cloth six times to remove sharp pieces of grit. Move part
across abrasive cloth six times. Check if rough areas have been removed. Use
above method until all rough areas have been removed. Be sure part is kept
flat on abrasive cloth as part is moved across abrasive cloth. Clean parts
in cleaning solvent P-D-680 to remove any grit on parts. Allow parts to air
dry.
