As the title says I need to ensure I know where the crank is exactly, or fix it.
The engine is the AJ26 and I thought that there was a peg to lock the crank when the transmission sensor is removed.
However, what I find when I remove it, and the rubber plate next to is is a triangular arrow on the plate.
Now, I'm not complaining, this should do the job, but I was expecting something to peg and hold it.
Have I been reading about newer engines perhaps?
Ive tried to upload my not very good quality photo....hope it works

There is a good photo of it at https://www.jaguarforums.com/for.um/...-bolts-109493/

 

Doh! I mean of course, the exact rotational position of the crank , not "where it is"

 

Ah, the penny's dropped.
You stick something the same size as the sensor back into its hole.

 

Based on tool JA-303-531 I think?

DO NOT USE THE TOOL TO LOCK THE CRANK FOR DAMPER BOLT REMOVAL!!!!!!!!!!!!!

You will risk damaging the torque converter drive plate timing segments.

Plenty of sad stories about this.

Perfect!
Have been back under the car with my DW turning the screw and lined up the curved hole.
Now just waiting for the tool.
(meanwhile a long 10mm socket sits there just to prove to myself that it can be done)
Thank you.

 

Thank you Motorcarman
Fortunately the pulley is off - all done from above.
What a palaver that was!
and great what you can do with angle iron, drills and bolts!

 

martinrichard, I read that you have bought the tool.

FYI for others who are interested, you can buy a complete Jaguar timing tool kit (that's how I searched for it) for less than $50 on eBay, including shipping. Some folks are selling the kit for 200 bucks, but I can't see what else you get for your extra bucks.

The kit includes (or should include) the plug(s - for AJ26 and AJ27, maybe others, you should confirm) to set the the torque converter drive plate (the tin pan with the funny shaped hole in it...), pins to hold the chain tensioners in place, plates to line up/time the camshafts, a tool to hold the cam chain sprockets in place, so you can remove and tighten them, and a special tool for doing something with the VVT that I avoided because I am afraid to touch the VVTs.

 

The AJ26 and AJ27 use the same locking tool. The AJ28 is different.

Thanks that's very helpful.
