CLEANING INSTRUCTIONS - Continued
10.
Mated Surfaces.
a.
Remove old gasket and/or sealing compound using a wire brush and solvent cleaning compound.
b.
Lightly coat with oil and wrap all parts subject to rust before storing.
11.
Rusted Surfaces. Clean all rusted surfaces using wire brush and crocus cloth.
12.
Oil-Bathed Internal Parts. Wipe oil-bathed internal parts clean with a lint-free cloth.
13.
Air-Actuated Internal Parts. Wash air-actuated internal parts clean with a lint-free cloth.
14.
Externally Exposed Parts. Wash externally exposed parts with soap and water. Rinse thoroughly and air dry.
15.
Hydraulic Cylinders.
a.
Care in handling of parts and hydraulic system cleanliness cannot be over stressed.
b.
Use ONLY the oil type and viscosity ranges specified under "Lubricants and Capacities".
c.
Wash all metal parts including cylinder in solvent. Dry all parts with filtered compressed air. Protect
components with a light film of oil. Flush cylinder with oil to remove all traces of solvent and protect
cylinder walls from oxidation.
d.
Check cylinder bore and rod surface for scratches and/or abrasions that may have been caused by grit
deposits in the cylinder packings. Carefully remove small rough or sharp surfaces with a fine-grained
stone. The closer these surfaces are to a mirror finish, the more efficiently the new packing will operate.
END OF TASK
INSPECTION INSTRUCTIONS
1.
General. All components and parts must be carefully checked to determine if they are serviceable for reuse,
if they can be repaired, or if they must be scrapped.
2.
Hydraulic Cylinders.
a.
Inspect all surfaces for burrs, scratches, nicks, scores and other abrasions. Stone or lap all burrs.
If scoring is deep enough to produce excessive leakage, replace valve assembly. Stone or use crocus
cloth on small scores.
b.
All parts with sliding fit must move freely in their bores.
c.
All grooves and passages must be free of foreign matter.
d.
Replace springs if they are broken or distorted.
e.
Replace all o-rings, seal rings, and gaskets.
f.
Listed below are instructions that must be followed to ensure correct installation and effective sealing
of o-rings.
(1)
Seal counterbores must be thoroughly cleaned.
(2)
o-rings, plungers, and counterbores must be lubricated on assembly.
(3)
o-rings must be free of molding defects and handling damage.
(4)
o-rings must not be stretched beyond the yield point.
(5)
Extreme care must be taken to avoid "rolling" the o-ring into the counterbore. (A twisted
o-ring is not likely to straighten itself after installation and is almost certain to leak.)
