Bush Hog 2165 manual Closed Center System

Page 35

Since the Power Beyond Kit is used with open-cen- ter tractor hydraulic systems, oil constantly flows from the pump, through the backhoe valve and the loader valve or other accessory valve, and then to the reservoir. See further in this manual for instruc- tions on proper assembly.

2.CLOSED CENTER SYSTEM: (2165)

Because a closed-center system requires no flow of oil through the backhoe control valve when the levers are in a neutral position, the 2165 backhoe must not be connected to a closed-center tractor hydraulic system. A PTO pump kit is required if the backhoe is to be mounted to a tractor with a closed-center hydraulic system.

IMPORTANT: Do not connect a 2165 backhoe control valve to a closed-center tractor hydraulic system, or serious damage to backhoe valve or tractor hydraulic system may result.

3.OPEN-CENTER SYSTEM WITH RETURN OIL NOT REQUIRED FOR LUBRICATION - Figure 19

The pressure hose (A) should be connected from the pressure port at the backhoe bulkhead connection to the pressure port of the tractor remote couplers or directly to the tractor valve. The return hose (B) should be connected from the tank (return) port at the backhoe bulkhead connection directly to a port on the reservoir, as shown in Figure 19.

IMPORTANT: Never connect the return hose to a tractor remote coupler which can be pressurized. Accidental pressurization can cause serious damage to backhoe valve.

4.OPEN-CENTER SYSTEM WITH RETURN OIL REQUIRED FOR LUBRICATION - Figure 20

On some tractors, the return oil cannot be routed directly to the reservoir because it is required for the lubrication of other functions. Check this characteris- tic with your dealer. The pressure hose (A) must be connected from the pressure port at the backhoe bulkhead connection to the pressure port of the trac- tor’s remote couplers or directly to the tractor valve. The return hose (B) must be connected from the tank (return) port at the backhoe bulkhead connec- tion to a surge relief valve as shown in Figure 20.

NOTE: The surge relief valve is not supplied with the backhoe or mounting kit and must be ordered sepa- rately to complete this type hydraulic hook-up.

Complete the hydraulic hook-up by connecting the surge relief valve to the return port of tractor remote couplers or directly to the tractor valve, and by con- necting a hose from TANK port of the surge relief valve to the tractor reservoir as shown in Figure 20. The surge relief valve is used to protect the backhoe valve from damage caused by accidental pressuriza- tion or high back pressure build-up. If this happens, oil will be vented from the TANK port of the surge relief valve to the tractor reservoir to prevent loss of vented oil.
