Nothing unusual. Buy a bottle brush and some degreaser, and scrub it clean.

does anyone as the part number for the springs? I guess after 100s of miles they must be a little tired and not as springy as when they come out the factory?
I would like to replace them while the DV are open.
Part numbers anyone?
Thank you.
POD this is a great DIY, thank you.

The springs don't usually need replacement, but it's good to have a couple on hand in case you lose one. If it happens to drop or go flying, it could be tough to find it. There's no harm in replacing them though.

[QUOTE=Parrot of Doom;1743167]In the image above you can see the crush washer (part 7f). This needs to be removed. Insert the end of a flat screwdriver under the lip of the washer, and gently slide it out.

Now the crush washer rests on a metal collar, the collar holds a very small cylinder of metal. This cylinder, from what we could gather, when the engine is running pushes against the spring and allows a small amount of fuel up the lines, through the injectors, and into the engine. I have been repeatedly warned not to disturb this but to my surprise the collar and little cylinder were quite happy to slide around inside the pump - they can't really not move, because the pump isn't horizontal anyway, its tilted to one side.

I think what may have happened is that someone has torqued the delivery valve back down, not taking care to ensure the collar is correctly centred in that little well, and the little cylinder hasn't been able to fully move - which would probably lead to damaged seals inside the pump, and a damaged delivery valve. With respect, its easily done as 7g moves around a fair bit, and the spring is carefully balanced - so take great care here.

Anyway, we removed it just to have a look:



There appear to be no keyways or anything, the pdf file (I will link it at the end) just says "observe the installed position". There is a groove along one edge, we just compared it to the collar on valve 5 and aligned it in the same direction. The little cylinder is flat to the top edge (with a small serial number stamped in), the bottom edge looks like a phillips screwdriver blade - probably so the diesel can counteract the rotational forces applied on the top edge when it pushes against the spring.

Obviously you don't have to remove this collar or the little cylinder

Is the "Little cylinder" the injection Element? and this item would measure 6mm with mic's?

My DVs were leaking so I did this job last Spring on my '91 300D 2.5T and I was also told the springs don't usually need to be replaced. I bought a set anyway as they were less than $6 I believe. I also had the o-rings and copper washers on hand. I compared the old springs to the new ones and the new ones were 1/4" or more longer so I replaced them. Everything is straightforward - Observe cleanliness at all times. I bought the special tool to remove the DVs from the IP. Keep the valve segment centered in the injection port, then do the same with the copper washer - and again with the spring. Be careful fitting the springs as they like to jump out and fall to the bottom of the engine. Once the engine was back together I started it and to my surprise it was noisier than before! I must admit, it was really quiet before so we were upset to hear the additional noises. So I opened things up again and put the old springs in with new washers. I was told the noise would go away after a week or 2 but I didn't want to wait so I went with old springs but the engine was still loud. But there was nothing else I could do at that point. The engine actually did get as quiet as it had been before, but it took about 2 weeks to do so. One day I may go back in and put the new springs in - I'd be interested to see if my fuel economy is affected.... It's a easy job all things considered.

Is the "Little cylinder" the injection Element? and this item would measure 6mm with mic's on the 606?

Basically, yes. You can remove the center plunger from the top, and yes and it would measure 6.0mm on a 606.96x turbo engine... on all other OM60x motors it would measure 5.5mm. You cannot remove the lower portion without complete pump disasasembly, as that piece comes out the bottom after the camshaft is removed.

This is the second time changing them ,on two diffeent car though. I do not remember who I bought them from the first time. Dealer has no clue. It's a 96 E300, I can't find anyone who even lists the crush wahers for the delivery valves. I do not need the O-rings, I have Viton coming.
Please reply

Copper washer = MB part # 004-997-45-40
O-ring = MB part # 017-997-41-48

Available from your favorite MB parts / WhirledPack vendor / dealer / etc.

I will try the stealership again. I really can't stand the service at the dealers near me. Not to mention names, but they are both located in Queens NY and on Northern blvd. They are to be avoided at all cost.
Unless you are dropping several hundred dollar at a shot, they want nothing to do with you.

No need to use the stealership, you can get them from any MB/European parts vendor. Most should have them for under $1 each. FastLane (forum sponsor) has the crush washers for $0.65 each...

Would these be the same part numbers for my 95 E300D (606.910)? I am trying to find them in the EPC for my particular model and I am not coming up with anything.

I believe they are the same for all Bosch M-type pumps used on all OM60x engines (with the exception of the .98x direct-injection models - these were never sold in the USA, and these didn't have an M-type pump). So yes, they will fit your 606.910 motor...

Thanks gsxr! I read your earlier post . . .

. . . . and assumed that this was the case. I called the dealer and they were having a lot of trouble trying to find something - as did I in the EPC. I am 99.9% confident it is the same, but then I talked to them and they were telling me I should pull out the oring and washer and measure then, which I did, but now the measurements don't jive with anything they are saying. I think there is just confusion because the EPC doesn't show an exploded view of the the delivery valve injector for the USA 606.910. I did search the EPC with the part numbers you listed and found them, but not under the 606.910 - now I forget what the model number was, but it was very close - perhaps it was just the Euro model as you have indicated. I'm just going to order them with the numbers you listed as they look exactly the same as POD's pictures. I agree that these are most likely the same for all Bosch M-type pumps used on all OM60x engines - I stated that to the dealership, I think they were just hesitant because those part numbers are not associted with the USA 606.910 in the EPC.

Thanks again.
