PLATFORM STEERING HYDRAULICS (CONT)
INSPECTION
WARNING
Compressed air used for cleaning/drying can create airborne particles that can
injure the eyes. Always wear eye protection. Pressure must not exceed 30 psi
(207 kPa) or injury to personnel may result.
Dry cleaning solvent (P-D-680, Type III) is used to clean parts and is potentially
dangerous to personnel and property. Extinguish all smoking materials and do not
allow sparks or open flames near the work area. Use skin and eye protection and
work in a well-ventilated area. Flash point of dry cleaning solvent is 200F (93C).
1.
Clean inside of hoses with compressed air. Clean outside of hoses with wiping rags. Clean all other components
with dry cleaning solvent.
2.
Inspect hoses for kinks, splits, deterioration, chafing, cuts, and loose fittings. If hose is defective, notify DS
maintenance.
3.
Inspect tubes for kinks, deterioration, chafing, gouges, and loose fittings. If tube is damaged, replace tube.
4.
Inspect other components for nicks, burrs, corrosion, stripped threads, broken castings, and pitting. If parts are
defective, replace as required.
INSTALLATION
CAUTION
Apply pipe sealant compound to the all male pipe threads of hydraulic fittings,
using only enough compound to coat the threads. Do not allow compound to
enter a component/fitting or the compound may restrict or block fluid passages
and damage to equipment or equipment failure may result.
Note positioning/orientation of fittings on the illustrations. It is important to have
the tightened fittings positioned as shown so that hoses are not too short and
fittings do not interfere with one another or damage to equipment may result.
1.
At streetside front, remove caps/plugs. Apply pipe sealant to all male threads. Install tube tee (38), reducer (37),
coupling nut (36), tube (35), tube nipple (34), and tube (33). Install tube tee (32), reducer (31), tube elbow (30),
and tube (29).
2.
At curbside front, remove caps/plugs. Apply pipe sealant to all male threads. Install tube tee (28), reducer (27),
coupling nut (26), and tube (25). Install tube tee (24), reducer (23), coupling nut (22), and tube (21).
