Hello,

I have a 2012 Disco 4, 3lt Diezel.

Going to attempt the Fuel Pump Belt (READ belt)

Is the belt timed? videos of the job they say it's not timed,
but the manual shows the flywheel has to be locked to lock the camshaft and
a lock on fuel pump sprocket (see attached)

Any advice from anyone who has done this job much appreciated.

Thanks

The fuel pump belt on a 3 litre is timed. The fuel pump belt on a 2.7 is not timed. The camshaft pin has to be installed before doing the pump belt. Some people will only do them with the body off. It is a doable thing with the body on, but it is very tight.

I didn't find out until after I struggled for a long time to change the belt that removing the battery and fuse panel surround and maybe the battery too reportedly makes the task a lot easier, especially when R&R'ing the belt cover.

No mention of it in my copy of the D4 WSM.

You would remove the battery box anyway to access 1 of the mount bolts for the crank case breather tube that mounts to the egr valve

Removing the coolant crossover as well as disconnecting the main harness connections from behind battery and bringing them across engine clears a lot of room. And battery box side.

Thanks for your replies,
Videos I've seen on this job are on the 2.7 ltr which explains why they say it's not timed,

I changed the timing belt this time last year but was pushed for time to do the fuel pump as well.

I have the tool to lock the flywheel from installing the timing belt, would the tool lock the camshaft in the correct position? (see attachment in first post)
Removing the starter to fit the turbo drain modification anyway.
Will just have to ensure the fuel pump sprocket is in the correct position before pulling the tensioner pin.

The manual doesn't describe removing the battery and wiring harness but that's the way they do it in the videos,
I will try it as per the manual and if it doesn't work, rip out the battery and harnesses.
The procedure is listed under 303-05 Accessory Drive TDV6 3.0L Diezel in the WSM. READ belt, Rear End Accessory Drive.

Thanks

I really struggled getting my hands in between the top of the engine and the body to manouvre the cover into place whereas with the battery removed I would expect to get at least 1 hand in through the gap at the side. I would never again attempt the task unless more space could be provided.

Hi there,

thanks for all your help, I have ordered the fuel pump sprocket holding tool today.

once the job is complete, I will report back, if I still have skin on my knuckles.

I recently made the same decision as I'm getting way past all the contortions needed to do these belts. An indie will be doing the belts on my 2016 D4 (138K) soon and then back up for sale it goes with absolutely nothing needing to be done.
And that will really be the truth not some smart arse sales talk.

This adds another level of complexity. I'm about to replace mine and didn't realise that the belt was timed. I've replaced one a TDV6 Territory and that was pretty straight forward and could be done with feel only. The SDV6 requires full visual so I think I'll need some sort of inspection camera along with the locking tools. I assume the timing isn't as critical as the front timing belt. My guess is its to ensure the pump produces a fuel pressure pulse at the optimum point for faster starting. I have noticed that there is slightly less cranking on the SDV6 compared with my TDV6.
Definitely not looking forward to this maintenance job.

Pet Budgie mirror is the better option,silicone it to a 2ft piece of 1/4" copper pipe.

I had one for years and it worked well,could bend it in any direction.

I assume the timing isn't as critical as the front timing belt.From my reading of the WSM it needs to be correct. I didn't find setting the timing was difficult although I rechecked several times before setting it in stone.

I've just looked at the WSM for this job and given the pain it is to lock the fly wheel, I think it can be done without doing so.
If I rotate the crank (with the old belt in situ) until the alignment marks are in the upper position as per the diagram from the WSM, and then place the pump locking tool in position and jiggle the crank until the locking tool fits. It should then be in the correct position. The old belt can then be removed with both the cam drive and pump in the right position. Given the effort in moving the crank by hand, there is no way the cam drive is going to move while fitting the new belt.
Any thoughts?

For those uninitiated in the dark arts of copper tubing, Scarry is referring to annealed or soft pipe, not the hard drawn tempered stuff sold in lengths vs coils of the soft stuff.

Lipstick makes a reasonable substitute for bearing blue if you're stuck and nailpolish for loctite.

Would it not be better to Silicone the budgie to the tube & then he/she could report back after all not having a mirror the poor little bugger would have nothing to do in it's absence always supposing it is a talking Budgie.

I doubt you could get a Sulphur Crested to stay on the tubing if it flapped it's wings but a Budgie would have no problem, IMHO.




Works for me.:Thump::Rolling:

Yes, and if the budgie starts hanging upside down on the tube, (and no it's not sleeping) you know you have an exhaust leak.

But if it had gripped the perch tightly before it snuffed it, it ran the risk of tipping the cage over in a Somersault Death Roll. You could lose your cage as it flip flopped down the street. Rand, I reckon you are bit weird, though I recall them using Canaries not Budgies, in Coal Mines to test for gas not budgies, though I stand corrected. That has gone out of fashion because of the introduction of Self Breathing Apparatus for Canaries but with some hesitancy, because the Canaries lived, so they were back to square one. That was created by the Ornithology Trades Unions by the Fly by Night Members & Shop Stewards Pecking Orders. I heard.
It may have been a tall Tail for all I know.[bighmmm]

just some info...

*yes rear belt is timed.
*if only doing rear belt, you dont need to lock the front crank pulleys or flywheel etc.
*battery out, battery box lower out, all that plastic round there.
*coolant cross over pipe off, or atleast disconnect from the passenger side (still need to disconnect one hose on the drivers side so the pipe will swing round to the drivers side of engine.
*pipes, brackets bits and pieces at the back, you will see them all, includes a pipe behind the belt cover.
*go down to your local tool shop and I'm sure you will find a mirror on a telescopic handle, prolly even a Kinchrome one.
*you can put a paint mark on the belt and rear gear on the pump and the housing to ensure you dont move anything.
*you wont be able to move the camshaft gear and the pump one is pretty stiff to move, so unlikely to accidently move anything.
*when doing it, put some form of cover/padding on the engine and lay on top of it with both hands down behind there.
*use your minds eye or jedi power and you will do it.
*the new belt goes on before the tensioner.
*the hardest part is getting the tensioner foot with the tab in its recessed part correctly.
*looking with the mirror spend time to see where the tensioner foot fits in.
*you will know when you have the tensioner in the correct spot as you can tighten the bolt initially up by hand.
*put a bit of loctite 243 on the bolt as all you are going to achieve is a nip up, then pull the pin.

In recently trying to find a new hpfp for my 2.7D the world of crazy irrational prices never fails to surprise. With hunting you can find the pumps for something around mid $2k but not easy to find new which in some ways seems cheap for such a technological masterpiece. I also checked with Ford dealers for the price of the belt and tensioner and they want about $1100 what a joke!!! Yes that’s the hpfp belt and not the front timing belt.

As I keep reminding 'er indoors whenever she comes home & complains about prices (on anything) This is the age of the Rip Off with Businesses trying to recoup losses made during Covid shutdowns etc. Now, whether they are justified depending on the Business is a moot point, even if they really haven't incurred those increases so it seems every Man, Woman & Dog decided to lift prices to play catchup but if they used their nouse & use this to bung prices etc up they would have kept prices low until the situation had settled down & take a hit & at least may still have a viable business.

I know,easy to say but why not. Do I perchance live in Cloud Cuckoo Land?:rulez:

What's the best way to remove the old belt? When I did the belt on my Territory I chomped thru the belt with a pair of side cutters. A very slow and awkward job. Others have suggested just remove the tensioner pulley but I was concerned it would mangle the retaining bolt on the last bit of thread.

i think you are over thinking it... the foot (for the want of a better word) of the tensioner fits neatly into a recessed area so difficult for it to fling out, but as others have said a razor blade will likely make short word of it.

You would remove the battery box anyway to access 1 of the mount bolts for the crank case breather tube that mounts to the egr valve

I'm attempting to do the fuel pump belt on my D4 for the second time, the first attempt I just gave up after getting the crossover pipe out. I've rallied some more courage and this time gotten to the point in the WSM ( step 12 picture E123760). Is this the crank case breather tube you mentioned? This must be one of the obvious differences between the 2.7 and 3.0 motors as all the Youtube videos based on the D3 don't mention this tube which must be removed to access the cover.
I must admit the WSM covering this job has scant detail, just pictures of various bolts and clips to remove with little detail on what to do or why you are doing it.
Has any one written up a procedure on this job?
