Hi all, can anybody help.I have purchased a second hand diesel injection pump for a freelander 2lt diesel xdi (non turbo). The problem being the shaft was not locked so the timing has been lost. Does anybody know the procedure for retiming or do I have to take it to a specialist. THANKS ALL.:mad:

Non-turbo??? Are you sure. I don't recall the Freelander being fitted NA.

According to Haynes its a dealer job if the timing has been lost. Sorry.
 
This is known as the High Pressure pump and it provides pressure to the common rail for all 4 injectors- injector timing (open and closing) is electronic controlled by the ECU. Therefore, where does the timing for the HP pump (aka Injector pump) come into the equation?
Baffled ??????????????????????/

To time that pump up you line up the woodruff key slot with a mark in the face of the pump. You will see a small score line on the face of the flange. Turn the shaft until the center of the woodruff key slot lines up and lock the pump.
 
It is stated to be an Xed. The fuel injection pump looks very much like the govenor controlled mechanical pumps, except that the govenor is the ECU. The pump also acts like a distributor on a petrol engine and selects the appropriate injector to pressurise. Therefore the 'timing' is important.

According to Haynes to remove the pump requires.

1 The pump pulley to be rotated to the timing reference position and locked with a pin.
2 The shaft lock bolt to be engaged on the pump assembly itself.
3 The lock pin removed from the pulley and then the pulley removed using a puller.
4 The pump then can be removed.

Dom139's problem is the pump he has obtained did not have its shaft lock engaged and as there isn't a reference keyway on the shaft and pulley then there is no way of finding the reference position. Haynes advises that in this situation the pump has to be take to an LR garage to have the reference position identified and the shaft lock engaged.
 
Is this a Game of state the obvious? “Dom139's problem is”
The above method is the exact way to time a pump that hasn’t been locked before removal. It is marked up when the pump is built. I have at least 2 of these every month and there has never been a problem. It’s just that not many people know that the mark is there.
The timing isn’t “important” it is critical. Without the pump being aligned up to that mark, the engine is either going nowhere or if started could cause engine damage.

MTECH is correct you need to time this pump/and engine parts . . . . .the drawing before was a td4 system and is completly different. . . . . .and yes the heinz manwell describes it well . . . . . . . .:) :) :)

Err, yes!! It is reasonable to assume that when someone asks for help they don't know the answer. Hell, I've stated the obvious again.

My response was for Dom139's benefit, oh and anyone else that reads this in the future for reference, given that within the thread it is stated 'common rail', which the L-series isn't.

Mtechuk has revealed a very useful tip about the timing of the pump so I've learnt something today also. My thanks for that.

Best of luck on your quest Dom139.
 
Hi all. Mtechuk you certainly know your stuff you were absolutely right.
I wonder if I may pick your brains again or anybody else who might know. I have fitted the injection pump with the shaft in the locked positin. Now I need to time it to the engine. I have the 2 lrt locking pins. I can see the holes on the the injection pump sprocket and back plate but cannot find the hole to lock the flywheel could anybody advise please. The illustration in the haynes manual is very vague.Many thanks.
 
Left side of engine, level with crankshaft, it's in the gearbox mounting plate. Timing pin pushes into a hole in the flywheel.

Following the wiring to the crank position sensor might help you locate it..
 
managed to find it by going to the local scrappies and having a look at a scrap engine. its nothing more than a drilled hole, no sleeve or any thing, managed to get between ird and bloch and squeeze it in! only trouble i have now is lumpy idle?????
 
You can now fine tune your pump timing. Mark all the pulleys up so you have a reference point.
Now undo the pulley on the pump end of the engine and rotate the pulley a fraction, about 1 tooth and lock the pulley back up. Start it up and see how it runs. You will not know in the beginning if your pump is advanced or retarded, it is trial and error. You will soon know my moving the pulley it will either run sweet or not at all.
