NOTE

Replacement of hydraulic hoses between hydraulic reservoir, filter, power steering pump, flow control

valve, fifth wheel lift cylinder locking valve, and fifth wheel lift cylinders is similar. The procedures

differ only in specifics: quantity of clamps supporting hoses, routing of hoses, and fittings at end of

hoses.

This work package describes replacement of a representative length of hose: between flow control

valve, located at crossmember above transmission, and right-side fifth wheel lift cylinder.

Diagram of fifth wheel lift hydraulic system is located in Figure 2 in WP 0137 00 (Diagrams).
