Manifold Removal (Fig. 24)
Manifold Installation (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.
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 Information section of this chapter).
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 beginning of the Service and Repairs section of this chapter. 4. Label all hydraulic connections for assembly purposes. 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.
3. Remove caps and plugs from disconnected hoses and fittings. 4. Lubricate and install new O--rings on manifold fittings. 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.
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 fittings in other manifold ports. 10.If necessary, remove hydraulic fittings from manifold. Discard any removed O--rings.
