NOTE: The ports on the manifold are marked for easy
identification of components. Example: RV is the relief
valve port and P1 is the gear pump connection port (see
Hydraulic Schematic in Chapter 10 -- Foldout Drawings
to identify the function of the hydraulic lines and car-
tridge valves at each port location).
