Manifold Removal (Fig. 24)
1. Park ProCore Processor on a level surface. Secure
machine lift axle to frame with hitch pin and lynch pin to
prevent lift axle from shifting. Make sure that ProCore
Processor engine is off. Remove key from the ignition
switch. Chock wheels to prevent movement of machine.
CAUTION
Operate all hydraulic controls to relieve system
pressure and to avoid injury from pressurized
hydraulic oil. See Relieving Hydraulic System
Pressure in the General Information section of
this chapter.
2. Make sure that Core Processor hydraulic system
pressure has been relieved before proceeding with tow
hitch manifold removal.
3. Read the General Precautions for Removing and
Installing Hydraulic System Components at the begin-
ning of the Service and Repairs section of this chapter.
4. Label all hydraulic connections for assembly pur-
poses. Thoroughly clean hydraulic connections prior to
loosening hydraulic hoses.
5. Disconnect hydraulic hoses from fittings in manifold.
Allow hoses to drain into a suitable container. Remove
and discard O--rings from fittings.
6. Put caps or plugs on disconnected hoses and fittings
to prevent contamination.
7. Disconnect wire harness connectors from solenoid
valve coils.
8. Remove two (2) cap screws, flat washers and lock
nuts that secure manifold to machine frame. Locate two
(2) spacers used between manifold and frame.
9. Remove tow hitch manifold from machine.
IMPORTANT: The hydraulic fitting in manifold port
C4 is an orificed fitting and is different than the fit-
tings in other manifold ports.
10.If necessary, remove hydraulic fittings from manifold.
Discard any removed O--rings.

Manifold Installation (Fig. 24)
1. If fittings were removed from manifold, lubricate and
place new O--rings to fittings. Install fittings into manifold
ports (see Hydraulic Fitting Installation in the General In-
formation section of this chapter).
2. Position tow hitch manifold to frame. Install two (2)
cap screws, flat washers and lock nuts but do not fully
tighten.
3. Remove caps and plugs from disconnected hoses
and fittings.
4. Lubricate and install new O--rings on manifold fit-
tings. Connect hydraulic hoses to fittings on manifold.
Properly tighten all connections (see Hydraulic Hose
and Tube Installation in the General Information section
of this chapter).
5. Secure tow hitch manifold to frame by tightening two
(2) lock nuts.
6. Connect wire harness connectors to solenoid valve
coils.
7. Operate machine functions slowly until air is out of
Core Processor hydraulic system.
8. Check oil level in tow vehicle hydraulic reservoir and
add correct oil if necessary.
