The bank valve (loader) is located on the right frame rail under the cab floor. The standard bank valve (loader) contains the following components:
- Inlet manifold (4)
- Lift control valve (2)
- Tilt control valve (1)
The inlet manifold (4) contains a load sense relief valve (3) and a flow control valve (5). Load sense relief (3) controls the system pressure for the loader and backhoe systems. This valve is adjustable. The LS pressure is generally set stalling the loader bucket Lift function. The LS drain relieves the pressure in the load sensing line when there is no call for pressure. The load sense drain valve is not adjustable.
The inlet manifold (4) for the bank valve (loader) also contains the steering priority valve (6) and the outlet to the tank. The lift control valve (2) controls the lift circuit. The tilt control valve (1) controls the tilt circuit.
The linkage rods connect the valve sections to the operator control levers. The loader control lever controls the lift circuit, the lowering operation, and the float detent for the bucket. The loader control also controls the bucket dump and bucket tilt function. If the machine is equipped with an auxiliary circuit, an auxiliary control lever is installed and connected to the auxiliary control valve.
The loader lever also contains transmission neutralizer button. When the button is pushed, the button disengages the transmission. Disengaging the transmission allows more power to be available to the hydraulic system.
