Removal
NOTE: The ports on the manifold are marked for easy
identification of components. Example: C1 is the con-
nection port from the LH decklift cylinder andCHG isthe
charge circuit connection (See Hydraulic Schematics to
identify the function of the hydraulic lines and cartridge
valves at each port).
1. Read the General Precautions for Removing and
Installing Hydraulic System Components at the begin-
ning of the Service and Repairs section of this chapter.
2. Disconnect hydraulic lines from manifold and put
caps or plugs on open hydraulic lines and fittings. Label
disconnected hydraulic lines for proper reassembly.
3. Remove hydraulic manifold from the frame using
