This is what Phil came up with for my 99 E300 (OM606.962)

0179974148 Injector Seal $.40ea

0049974540 Delivery Valve Washer $.90ea

It's correct that the o-rings and copper washers are the same as those for the OM603 such as the 87 300D. I don't know why these parts are not being carried for the OM606.

I didn't know that one is supposed to replace the compression springs when doing this job. I don't even see these in the catalog. I also don't know why but after each time I did this job I got more nailing at idle, but it should subside eventually. It took my '96 about a month after this job to get rid of the idle knock when warm; there's still some when the engine is cold but it was there before the job too. Also I don't see any need for taking out the pressure valve and carrier while doing this job, only what's above these parts.

Anyone out there with a clue as to spring p/n or supplier? Good thread. Thanks. You guys are diesel gods.

Get the number off of the side of the injection pump and take it to an authorized Bosch distributor and they can sell you the spring (along with anything else needed for the pump). I have found the local MB dealer kind of useless when it comes to parts for the Bosch fuel injection pump.

The MB PN for the delivery valve springs are A 001 074 21 93 and they list for $6 each from MB. I don't think they routinely need replacing though unless you lose one or find one broken regardless of what the WIS says.

Great Post
We need more of these.

Johnhef · #12 12-22-2006, 09:54 PM

Be careful though! don't remove anything below the copper washer- if the cylinder comes out and you don't line it up correctly on installation and still torque everything down on top of it, you can damage the pump! :fork_off:

When I did my ip gasket job on the euro the part numbers that i got from Phil,the dealer, and Bosch were all different. I measured them with my digital calipers and they were different by a couple of tenths of a mm in both ID and OD. I wouldn't use anything that wasnt from Bosch directly for euro versions. The Bosch service person told me that the gaskets for different engine groups may not be interchangable.

I'd bet they are the same parts but variations in rubber molded o-rings would allow for a tolerance like that. The fact is that none of these are "custom made" they are stock metric o-rings and they are made to within 1MM sizes of varying thicknesses. A couple of tenths of a mm is just the dimensional tolerance of a rubber part.

I am talking about the gaskets not the o rings. The o rings are the same. I wouldnt use the wrong gaskets. it is possible that they effect the operation of the pump. This info comes straight from a bosch diesel injection specialist . my ip is for a euro 240d and the gaskets are specific to this pump. They may be interchangable with some, but not all. when I asked him how much of a difference it would be, he didnt know. the gaskets go up in size accordingly to the part no. All of them are easily purchaced through Bosch. To me it makes sense. Those gaskets have to seal perfectly. If they dont match with your delivery tube there may be internal leakage. After i removed the washers that were not for my pump one seemed to stick inside of my delivery tube like the washer was too large. I am hopeing nothing internal was altered. It still runs fine. I have done some research on this. these things look identical to the naked eye. They must have a reason for being different otherwise Bosch wouldn't make them that way.
