TD5 Fuel Pump Locking Ring

[DiscoCam]

Hi all

Spent this afternoon putting in a new fuel pump for my D2. For the life of me I can't seem to get the locking ring back on. I don't have the LRT-19-009 tool referred to in Rave and came very close to using the hammer that I got it off with to finish it permantly:twisted:. Deep breaths...

Are there any hints or tips for this mechanically challenged numpty for round 2 in the morning?

Thanks

are you talking pump or filter? dont remember a locking ring on the filter, just screw it on and then screw the water sensor thingy on.

Oops - Thanks Yorkie. Definitely the pump.

Yes, they can be a bit frustrating.


IF you have a helper, get them to press the pump down in place while you start the lock ring thread. Otherwise no, there isn't any easy way. I feel your pain:(

If you've got access to a welder, knocking up one of these 'special' tools will make the job a bit easier. You'll be able to press down and turn at the same time, with turning force on two sides of locking ring.

A bit of lube on the seals should also help....

Thanks guys.

Nice bit of engineering Xtreme. With my welding skills though I'd spend 5 hrs making something similar to find out it didn't quite fit.

Will apply some more elbow grease & perseverance in the morning.

naff the special tool

block of wood, cut it out so that it fits over the fittings on the pump and inside the ring.

get it all ready to go in and then kneel on top of the block of wood ontop of the pump the lock ring goes on easy

I did a pump the other day. Admittedly I have a long range tank and so instead of spinning the locking ring on, I had to fit 6 or 8 little screws. I pretty much just pressed down on the pump with the front of my shoe to hold it down and then stuffed around trying to get the screws in. That may also work for you.

Place the the heel of your boot on the center pump to push it down. Once down far enough and the ring will go on easily. Make certain that the seal is in place correctly.

I agree they can be a real pain to start.

if the rubber seal is in the wrong position you will not get it down, place the pump in position and ensure the seal is low enough....use your fingers....to contact the seal ring and it should go down low enough to start the thread on the locking ring.
there is a pictorial in here somewhere....a search (hahaha) might find it.

Oh! Also, when I replaced mine, the new pump had a tab on the side at the top - the old pump didn't have this. The new pump wouldn't seat at all until I cut the tab off. Just compare your pumps to see if thats the problem.

[DiscoCam]

Thanks again for replies guys. I wondered if I had seated the seal correctly, and it looked OK in the faiding light yesterday but will have another look this afternoon. Off to a wedding this morning - must be 10/10/10.

Think I'll try the block of wood trick too - thanks Blknight.

Will post of my success tonight!!:)

How true. Seams the seal was not seated correctly :eek: and after fixing that I had the locking ring on in under a minute.:D

Unfortunately I flattened the battery in previous starting attempts and there wasn't enough juice to start it. The pump definitely works so we should be good to go tomorrow after a night on the charger.

Thanks again

Before trying to start the engine, also make sure you've done priming sequence (ignition on & press accel pedal half a dozen times) about 5-6 times to make sure the engine has got fuel.

I'm pretty sure on the D2 at least you turn the ignition on which will activate the fuel pump. Wait until the fuel pump times out. Do this 3 times. This brings fuel up to the engine and purges any air.

Accelerator on the floor and crank engine for no longer than 30 secs at a time. The accelerator action lets the ECU you are starting with a purged engine and to let the fuel through the injectors. Once the engine gets to 600rpm I think it was then you let off the accelerator.

Getting a Pauline Hansen on the accelerator pedal part????
Whats it supposed to achieve????
Afterall, being common rail diesel and drive by wire.....

Tapping the accelerator tells the ECU to go into extended purge, which runs the pump for a couple of minutes at a go, instead of the usual 30 seconds.

When I did it, the fuel level was low, but so long as the pickup is submerged, I can't see how the level would affect how long it would take.

Yeah, the flat-to-the-floor when starting is the other half of it which I couldn't remember of the top of my head.

The owner's handbook has the exact details (for the whole lot) in it.
What I wrote was the simple version I remembered from when I had to do it a few months ago. ;)
