BLEEDING Bleeding procedure will remain basically the same regardless of whether dual or single filters are used. The following is based on the tractor being equipped with dual filters and when bleeding models with single filter ignore reference to rear and front filter bleed screws. Open rear bleed screw on filter head and actuate hand (priming) lever on fuel lift pump until fuel flowing from bleed screw is free of bubbles. Close the rear bleed screw and open front bleed screw on filter head and actuate primer lever until bubble free fuel flows from opening. Then close the fuel filter bleed screw, open front bleed screw on fuel injection pump and actuate primer lever until fuel flowing from bleed screw is free of bubbles. Close the pump bleed screw while actuating primer lever. Loosen the fuel injector lines at the injectors and crank engine until fuel appears at all injectors, then tighten the fuel injector line connections and start engine.
