The ports on the rear traction manifold are marked for
easy identification of components. Example: P2 is a pis-
ton pump connection port and RV is the location for the
relief valve (see Hydraulic Schematic in Chapter 10 -
Foldout Drawings to identify the function of the hydraulic
lines and cartridge valves at each port).
The rear traction manifold uses several zero leak plugs.
These plugs have a tapered sealing surface on the plug
head that is designed to resist vibration induced plug
loosening. The zero leak plugs also have an O- ring as
a secondary seal. If zero leak plug removal is necessary,
lightly rap the plug head using a punch and hammer be-
fore using an allen wrench to remove the plug: the im-
pact will allow plug removal with less chance of damage
to the socket head of the plug.

For rear traction manifold cartridge valve service proce-
dures, see Control Manifold Cartridge Valve Service in
this section. Refer to Figure 59 for rear traction manifold
cartridge valve and plug installation torque.
IMPORTANT: A flow control orifice (item 7) is lo-
cated beneath the hydraulic fitting in rear traction
manifold port T/OR1. If the orifice is removed from
this manifold port, make sure to label its position for
assembly purposes. When installing the orifice in
the manifold, make sure that the orifice is properly
tightened in the port.
