NOTE: The ports on the filter manifold are marked for
easy identification of components. Example: P2 is the
gear pump connection port and T is the connection for
the hydraulic reservoir return port (see Hydraulic Sche-
matic in Chapter 10 -- Foldout Drawings to identify the
function of the hydraulic lines and cartridge valves at
each port).
