How do you remove fuel injection pump gear?
Apply sufficient pressure to fuel injection pump gear (2) in a counterclockwise direction in order to remove the backlash. Lock fuel injection pump (3) in this position. In order to lock fuel injection pump (3), loosen locking screw (4) in the fuel injection pump. Slide spacer (5) into Position (YY).
How does a diesel fuel injection pump work?
In simple terms – there is a valve mounted on the rear or side of the diesel fuel injection pump. This valve has an arm attached to it that goes down inside the pump. When vacuum (suction) is applied to this valve, the lever moves and shuts the fuel flow off inside the pump. Without fuel the engine cannot continue to run.
What happens if the fuel injector doesn’t close?
If the injector can’t close, cylinder performance is compromised. Whenever the fuel injector pump’s O-rings or ball seats are defective, the timing of the fuel transfer process is disrupted. This is a common diesel fuel injector pump glitch, and usually requires a complete injection pump rebuild or replacement.
How does the fuel pump work in a JCB engine?
The crankshaft also drives a mechanical fuel injection pump via gears. The pump injects fuel via injectors, or atomisers into each cylinder in time with the four stroke cycle. Fuel is pumped from a fuel tank to the injection pump by means of a lift pump driven by cam lobes on the camshaft.
Apply sufficient pressure to fuel injection pump gear (2) in a counterclockwise direction in order to remove the backlash. Lock fuel injection pump (3) in this position. In order to lock fuel injection pump (3), loosen locking screw (4) in the fuel injection pump. Slide spacer (5) into Position (YY).
What should I do if my fuel pump is not working?
Remove the fuel supply hose and the fuel inlet fitting from the gear pump. Check the gear pump while cranking the engine. The gear pump gears mustturn. 2. If the gear pump gears do notturn, remove the fuel pump. 3. Crank the engine and check the air compressor or the accessory drive shaft for rotation.

How do you lock a fuel injection pump?
Lock fuel injection pump (3) in this position. In order to lock fuel injection pump (3), loosen locking screw (4) in the fuel injection pump. Slide spacer (5) into Position (YY). Tighten locking screw (4) against the shaft of the fuel injection pump to a torque of 9 N·m (80 lb in). Alignment of timing marks 5.
How do you remove a Perkins injection pump?
After these three bolts are removed, use a 13mm socket to remove the three nuts that hold the injection pump to the block. The pump is now free. Had you first removed the three nuts that held the pump to the block, the pump would have flopped around making it difficult to unbolt the injection pump drive gear. P.S.
Where are the nuts on an injection pump?
After disconnecting the fuel injection lines, use a 12mm socket to remove the three bolts that are located at the very front of the injection pump which holds the pump drive gear to the pump. After these three bolts are removed, use a 13mm socket to remove the three nuts that hold the injection pump to the block.
Where is the injector pump on a diesel car?
Locate the injector pump, which is typically on the driver’s side framerail. Open the drain valve at the bottom of the fuel filter/water separator in the engine bay with your hands to lower the fuel pressure. Unplug the harness running to the injector pump. Disconnect the quick-disconnect clips leading to the injector pump with your hands.
