Crankshaft Trigger ring - CKP
Click image to enlarge
I'm putting this on the forum for future reference should anyone be searching for info on the above.
I have marked out the magnets on the trigger ring for the crankshaft sensor which show where the magnets are and where the trigger point - i assume - for the injection timing etc.
My reason for doing this is that LR want something like £120.00 for this item which they say is not re-usable (although i think it is as long as it is removed carefully without distortion and refitted using bearing/threadlock applied to the inner face for peace of mind - mine is slightly distorted now).
Bearmach do one for approx £17.00 but there are none available although listed on quite a few sites - maybe LR have told their supplier to desist from supplying
Funnily enough (!!!!) under LR's old parts numbering these items were much much cheaper closer to the BM price
Citroen/Peugeot do them for £24.04 so that is where i may look for my supply, however, i am wary that the crank timing may be different as different power for their 2.7's v D3.
I will probably order a Citroen item and if the magnet spacings correspond - which i think they should as most diesel injection points are at TDC, then i will be confident about using the Citroen/ Peugeot item for a fraction of the price and the world will be a little wiser to JLR's parts ripoff.

I think you will find most diesel injection points are before tdc.

Yes you are right as the burn/front rate of diesel is slower than petrol, but this exercise was more to see that the trigger points are the same between the LR and Citroen/Peugeot product.

They are not used as trigger points, just as reference points for the PCM; so I would be surprised if the arrangement varied on the Citroen / Peugeot part.

It would be good if they are the same, and an feeling more confident based on above comments.
Hopefully save people about £100, especially since the trigger ring has to be removed to change the rear crank seal as well.

Got the trigger ring from Citroen dealer for £22 including 'trade' discount.
So my efforts at marking out the existing trigger ring were to an extent in vain
That's because the part number inside the ring is exactly the same as the one from my Discovery
So it is indeed the same item, saving in excess of £100 from buying from Landrover.
As i am not on the Range Rover or Jaguar forums, anyone wishing to post the above information for their benefit and information, please feel free. Might be useful to the South African and Aussie forums as well.

Great news and, given how these are used by the PCM, not a total surprise. The Land Rover Tax on items supplied through them, but not made by them, is becoming a bit of a horror story.
There is just no justification for what JLR is doing with part prices and most customers will just not be aware of the huge premium they are paying for someone to put a sticker on a box. I used the ATF for the 8-speed gearbox as an example the other day:
Dealer price for LR023288 ZF Lifeguard 8 = £75 per litre x 5L = £375.00
Eurospare ZF Lifeguard 8 (no JLR sticker) = £22.36 x 5L = £111.80
All the above gets you the same identical product, in the same bottle, with the same label.
Of course, ZF does not actually blend their own oil and they just repackage stuff from Shell that conforms to the specification. My most recent purchase of this specific ATF was from Mannol:
Mannol ATF AG60 = £4.21 x 5L = £21.05
Anyway you look at it it is an astonishing difference in price.Land Rover - Turning Drivers into Mechanics Since 1948

Way way back in the 70's I needed a distributor cap for A Range Rover and was quoted something like £40 I got one from Rover for a P6 3.5s less than £5 same Lucas box same Lucas part number just plane robbery and still going on.

Is it worth putting a 'sticky' for JLR spec (or genuine) items available for lower prices but without the JLR sticker?
Oil pumps and the CKP trigger to start with.

Good afternoon, all.
Installing a Crank magnetic trigger ring seems to be a huge trade secret. I am trying to install one with the special tool.
My question is, "does the engine need to be at TDC when you install the ring?"
Please help. This seems to be a very difficult procedure.
Kind regards. Digby Leih.

If you have the special tool for fitting, then the engine does not need to be in any particular position.
The tool fits onto the crankshaft plate in a specific position only so it cannot go wrong.
