Fuel Pump Belt

[Woz]

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
Woz

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.

That's the process in the manual, provides a lot more room to move.

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.
