Hello guys,
Could those of you who have had experience removing the fuel pump tell me where to fit the timing securing socket?
I am about to attempt this tomorrow and am making very sure I am doing what I should be before commencing, to me this is the most important bit.
Thanks
Hi this may help disconnect the battery negative lead, then remove the intake manifold, remove the starter motor, undo the bolts securing the upper tie -rod to the right hand engine mounting bracket.
Remove the under tray, position a jack underneath the engine, with a block of wood on the jack head and take the weight of the engine.
Unscrew the four bolts and one nut securing the right-hand engine mounting bracket to the engine and Hydramount you may have to remove auxiliary drive belt.
Using a 17mm Allen key or a bolts with a couple of nuts locked onto it, unscrew the large access plug in the timing chain cover, the seal should be really renewed.
Slacken and remove the fuel pump sprocket nut.
Now screw land Rover tool LRT 12-178/1 into the timing chain cover, then screw Land rover tool LRT12-178 into the pump drive sprocket.
Carefully tighten the centre bolt of the tool, and free the sprocket from the pump.
hopefully you will have removed the wiring plug from the fuel pump beforehand, and removed the bolt securing the fuel pipe bracket to the oil filter housing.
Remove the bolt securing the fuel pipe to the coolant rail.
Put some cloths under the fuel pump, then release the retaining clips and disconnect the fuel hoses from the pump.
Undo the two union nuts, and remove the two high-pressure fuel pipe from the fuel pump to the common fuel rail.
Disconnect the wiring plugs from No1 & 2 glow plugs.
Now undo the three mounting nuts and remove the fuel pump, discard the gasket as a new one must be used.
Refitting is reversal but making sure that mating surfaces of the pump and engine are clean and dry and fit the new pump gasket.
Position the fuel pump, and tighten the mounting nuts to the specified torque.
Re-fit the glow lugs.
Ensure the high-pressure fuel pipe unions are clean and refit the pipe, tighten the unions to the right specified torque.
Reconnect the fuel hoses to the pump, and secure them in place with the retaining clips.
Refit the bolts securing the fuel pipes to the oil filter housing and coolant rail.
Reconnect the wiring plug to the fuel pump.
The land rover special tool used to release the fuel pump drive sprocket and hold the sprocket in position, can now be unscrewed slowly and carefully, and then refit and tighten the sprocket retaining nut to the specified torque.
Make sure the timing cover access plug is clean and use a new seal if you have one, again as always tighten to the specified torque.
Refit the auxiliary drive belt.
Refit the right hand engine mounting bracket to the Hydramount and the engine.
Fit the bolts and nuts tighten to specified torque.
Refit the upper tie rod to the engine mounting bracket and tighten the bolt, remove the jack refit the under tray.
Refit the starter motor.
Refit intake manifold.
Reconnect the battery negative lead.
Prime the pump by putting the ignition to II turn it off repeat this a few times, turn it off once more then follow below.
Depress the accelerator pedal to the floor then start the engine as normal it may take longer than usual if so operate the starter in 10 second bursts with at least 5 second rests in between, once started run the engine at fast idle to purge any remaining trapped air from the fuel lines, the engine then should idle smoothly at a constant 850rpm
Good luck and please report back maybe taking photo's as you go through the job
