Hello folks,
Start laughing now and get it out of your system.
Finished? Good.
Does anyone know of an on-line supplier (other than eBay) who can supply me with a seal kit for the injector pump on my DSE?
I need it rather quickly as I'm supposed to be driving the family up to Yorkshire next weekend for the father-in-laws 60th birthday party.
Cheers,
Smiler.
Might be worth looking for a kit for a BMW as it's the same engine as the older 525d. You might have more suppliers to choose from then.
Ta, already been looking (I previously had an E34 525TDS Tourer) but not much found on the first trawl. I'll have another look at ebay (only british seller is on holiday, rest are in eastern Europe) and see if I can pick out some part numbers and try my luck that way.
I found this:
Ok, the seller is in Germany - but lists it as working on the 2.5 P38..
More interestingly though than waiting from Germany, there's a Bosch part number listed: 2467010003
Which brings up things like this:
http://www.ebay.co.uk/itm/BMW-E36-E38-E34-E39-2-5-TD-TDS-DIESEL-BOSCH-FUEL-PUMP-REPAIR-KIT-GASKET-/222079579960?
http://www.ebay.co.uk/itm/BOSCH-Repair-Kit-2467010003-/302361719195?
and a whole host of others too...
Looks like the Bosch part number is the best to search by :)
Cheers Marty, I have to admit it was rather late when I started the search so I hadn't expanded my search that far yet. I have finished work early today so will now have a look. The last link you supplied above is showing delivery for tuesday which is doable if it fixes it.
Right, got one on order. Should arrive on tuesday (it better had!).
I now need to make sure I know exactly what I'm doing. There is a surprising lack of decent youtube videos out there on this. Perhaps I should tun it into a magazine article (actually, perhaps not, that's guaranteed to jinx it).
Can't hurt to make notes on it..
Have a look also for 'Bosch VE' pump seals or something like that - I will have a look, but I think I found some pictures of one being stripped down, so if I can find it again, I'll post a link up for you.
Marty
Cheers Marty.
I just found an old Bosch training video describing the operation of the VE pump which was a great help in at least understanding what's going on in there. It appears that the entire body is full of fuel which puts my mind at rest a bit that it's not an internal seal that has failed and is flooding the thing.
I saw the word "diesel" and knew it was you! 😊
I like to be just that little bit different. 🙂
I have also found a video of two blokes repairing a similar pump from the same family with the same leaks. It looks like it's perhaps not such a big deal if you are careful (oh dear...) and know what you are doing.
From what I have learnt so far it would appear that the only real killer leak is if the shaft 'O' ring fails allowing fuel into the engine through the timing chain cavity.
I might look at buying a spare scrap pump to rebuild and create a guide for others.
Smiler.
You'll be fine. It'll be the same as refurbishing a valve block or modulator. Don't rush (although I know you have a deadline) and just work your way through.
Good luck.
Right, made a start today. The engine bay is looking even emptier!
Top half of the pump containing the fuel quantity control gubbins is all off so that'll never be the same again.
Unfortunately my pump differs from that in the video I mentioned and my pump internals are becoming unloaded before I have the O-ring under the pump head fully exposed. This is bad as it means the shims will fall out of position inside the guts of the pump. I am currently reviewing my options. I might go hunting for some small off-cuts of wood tomorrow to try to fashion some wedges from...
A bit more work yesterday evening. I try'd something and appear to have succeeded in replacing the pump head seal without loosing anything inside. The head has certainly bolted back down fully home anyway.
The quantity control lump has been refitted to the top with its new seals and the engine rebuilt around it all minus inlet manifold.
This evening I intend to bleed the fuel system and attempt a start. I may need to make very minor adjustments to the quantity controller (it is REALLY sensitive apparently) but hopefully I'll get a nice smooth (it's a diesel, everything is relative) idle and it'll respond to the accelerator pedal.
If all is good I shall refit the inlet manifold and plumbing and take her for a test drive and then come home and bask in my own heroic glory.
If I've ballsed it up I shall finish off that whisky bottle!
Good work!
If you put some light scratch marks on the bits as you took them apart, then if they all line up on reassembly, then it should be pretty close (from what I understand from the bits I've seen/read about the diesel FIP)..
Hope you took lots of pictures... I'm interested to see what's inside the FIP, since it seems to be one of those things on the diesels that if it doesn't work properly, then nothing else does!
Cheers Marty, though it might still not work yet.
I made a couple of marks on the quantity controller body but these things are so sensitive apparently that even tightening the mounting bolts changes the settings!
Lots of photos taken right up to the scary bit. Then I got too focused and failed to take any (not that I had any spare hands to hold a camera/phone.
Couldn't get any decent shots of the gubbins inside as it was in a dark hole surrounded by bright aluminium so neither phone nor camera would focus in.
Success! Turns out I really am a mechanical genius/god!
The first start was a bit shaky with no rev-counter, a high pulsing idle, a locked out EAS and an alternator failure message. But after a brief panic, a quick search on google and a check of all electrical connectors I found a plug dangling underneath the starter motor. Once it was plugged back into the crank position sensor all was back to normal.
Having said all that, I haven't actually driven it yet...
Nice work!

I think you proved that at Summer Camp by spending a day adjusting Marty's wheel alignment. Anyone else would have given up, thrown their tools in the back and told him to take it to Kwik Fit......
Thank you.
To be fair Martys tracking only took as long as it did because of the bent adjuster on the track rod.
Driving around it became apparent that it was a little more hesitant pulling out of junctions. A small adjustment with a big hammer now has it slightly more responsive than it was previously but with no adverse effect on the idle. So looking good.
At the end of the day there is only so much that can be adjusted with a diesel, there is no air/fuel mixture to worry about and no ignition timing to get excited over.
Just injection timing, set by rotating the pump body much like rotating an ignition system distributor which hasn't been disturbed; and fuel quantity which is the bit that I have been playing with. The more fuel the more revs so just back it off and then start slowly increasing it until you get the correct idle speed. Basically the equivalent of setting the idle stop on a carb or throttle body.

Ah, that was my Friday. New track rod fitted, ends nominally the same distance as the old, then up the road, stop, adjust, down the road, stop adjust, etc., etc.. Got there in the end!
Sounds like you've got the pump cracked anyway 😊
