Good luck from me too, you'll be going well if you do it in a day, it took me closer to three days as it's a biggy.

Hi Guys, I replaced the clutch in my TD4 recently and took note of the list of jobs to do. Not many photo's I'm afraid but hopefully enough. This was how I did it, I'm not claiming it is the right way or best way but it worked for me. It would be great if others shared their experience and maybe say where I could have done it better or easier. Make sure you have the Rave manual open (at page 627 I think) for the correct procedure.
I didn't undo the lower ball joints on the wishbones as I didn't want to damage them and they didn't pop out by hammering the end of the strut so I unbolted the wishbones at the rear bush and front pivot bolt. This meant I could get the drive shafts out by pulling the whole strut out. It might have been easier if I had loosened the nuts on the top of the struts but it worked anyway.
0. Unbolt propshaft from IRD and tie up.
1. Disconect battery and unbolt the battery tray.
2. Remove engine cover and air duct feed to the EGR.
3. Remove starter motor (I just took the bolts out and left it sitting.)
4. Jack the front of the car up as high as you can and get it on axle stands
5. Take the wheels off.
6. Take the undertray and side panels off.
7. Drain the coolant.
8. Drain the gearbox oil. Not sure if it must be done but I was intending to change the oil anyway.
9. Unbolt the wishbones front and rear supports and leave them still attached to the ball joints but supported on a bungie.
10. Unbolt the lower end of both drop links.
11. Remove the two remaining bolts holding the subframe and it should drop down. (Note I had sprayed around the mounts with paint earlier so that I could see where they should go when refitting).
12. Using a pry bar pop the drive shafts out. The struts should swing out enough to let you get them out of the way but you might need to turn the steering to get the upper ball joints in the right position or they can hold them back. Support them with a bungie and pull an old rubber glove or similar over the ends to protect them from dirt. I also jammed clean rags into the drive shaft sockets.
13. Release the two coolant hoses on the IRD and catch what water is still in the system. (note this might be easier done after lowering the engine but this was when I did it)
14. Pull the breather pipe out of the top of the IRD.
15. Remove the bolts holding the lower engine tie bar and remove the tie bar.
16. Remove the lower tie bar brackets and RHS IRD bolts.
17. Remove the four bolts holding the IRD to the gearbox (the top two are very awkward and will need a swivel on a long extension bar) and wrestle it off the splines, it’s very heavy, be careful. (Note this is the order Rave says but it might be easier to lower the engine first)
Now would be a good time to drain the IRD oil if it hasn’t been done in a long time.
18. Disconnect the clutch hydrolic line at the connection just above the gearbox. It has a plastic sleeve which slides in to release the connection and out to secure it (a bit like fuel line connections). I used very long nose pointy pliers to squeeze the sleeve in and release it.
19. Disconnect the first and reverse gear electrical sensor connections.
20. Pop the gear linkage ball joints at the gearbox end. I used a claw hammer for this which worked well, I didn’t take the linkage off even though Rave says you should. It made removing the gearbox a bit more awkward but still do-able. As I had removed the subframe and dropped the engine a bit I had just enough room.
20a. Unhook the front two exhaust support rubbers. (Rave says to unbolt it from the manifold but I didn't need to)
21. Find some way to support the engine as the next step is to unbolt the N/S engine/gearbox mount. I used an engine hoist and lowered the sump onto a piece of wood that was on a milk crate.
I had the inlet manifold off too but this shouldn't be necessary, I was doing other stuff at the same time.
22. Remove the N/S engine mount and allow the engine/gearbox to sag down onto a support (approx 2-3 inches).
23. Remove the support bracket from the gearbox.
24. Attach a hoist to the gearbox. (I used an eye on the top of the gearbox)
25. Remove the bolts holding the gearbox to the engine.
26. Remove the small bolt that was behind the IRD (10mm) holding the thin metal plate to the gearbox. I hadn’t done this and the plate caught on a dowel causeing a bit of grief until I realised what was happening..
27. Lever the gearbox off the engine and wriggle it out of the gap. The gear linkage will catch on the chassis leg but if the engine has been lowered enough it should come out with a bit of twisting and pulling. I used an engine hoist to support it and lower it down, If you don’t have one then you’ll need help.
28. Replace the slave cylinder and thrust bearing.
29. Remove the pressure plate and friction plate.
30. At this stage I cleaned the flywheel and scuffed it a bit with a wire wheel on a grinder. I didn’t replace the fly wheel, maybe I should have but it wasn’t showing any signs of failure and felt tight when I checked it. Time will tell if this was a stupid thing to do but I didn’t fancy paying out another £300 for a new flywheel. Some say the flywheel should last as long as two clutches, I hope they’re right.
31. Bolt on the new clutch parts making sure the friction plate is centred. I cobbled together a tool to do this using a roll of tape and a couple of sockets. Allan bolts should be 25Nm, don’t know if it was overkill but I used threadlock.
Once in and the bolts tightened a bit I double checked checked the friction plate was centred by measuring from the centreing tool I'd thrown together. (a 1/2" socket adapter with some tape wrapped round it
32. Refit everything in reverse order.
I used a trolley jack to lift the IRD into position before raising the engine and gearbox. I think it was easier to access the bolts with the engine lowered.
I should have refitted the IRD breather too but forgot and only remembered while typing this up. Doh!
33. Bleed the clutch.
At this point hopefully you have a good working clutch, unfortunately my master cylinder gave up while bleeding so I'm waiting for a new one.
