as the owner or 2 (yes I know !) discovery TD5's I'm always busy .
Doing the black autos head gasket and found this !!!



Difficult job ? I can see the crank pulley and front engine casing need to come off and I believe the sump none of which fazes me apart from the crank pulley !! Any tips ?

I understand it is F tight, ideal would be a realy good impact gun. I have seen posts where people make a brace from angle iron or similar bolt it to the pulley then jam this against the ground and use a huge bar or even hire a big torque wrench which will remove the bolt and allow them to torque it up correctly when it goes back.
Try a quick Google and see if you can find some inspiration.

I used an old sepentine belt and a 5ft Scaffold pole to undo the crank pulley bolt
I've got a photo somewhere, I'll try and dig it out

Here you go

That was to tighten but just reverse the belt to slacken

(That was on a 300 Disco)

Now , as the heads off I have the engine timed up ( crank locked with the bell housing tool ) will that be enough to hold it ?

Not sure how strong the pins are but If it takes a 5 foot pole to move the pulley bolt that would be quite a bit of force, don't want to bust the pin or worse damage the bell housing.

What ever you improvise be aware that the crank damper's bolt is(should be) tightened to 460Nm and you need a new one dont reuse the old

On the plus side it will allow me to do the oil pump bolt at the same time

Absolutely not! The locking pins and the holes they locate in are not designed to take that kind of load.

Bought a flywheel locking tool in the end and a hand (hammer actually) impact wrench designed especially for crank nuts .
3 blows and it was cracked , easy !
