Fuel Delivery Valve Leak - Where to get parts? - PeachParts Mercedes-Benz Forum

no-blue-screen · #1 07-21-2006, 09:16 AM

Hi all,

I have a small Diesel leak at one of my fuel delivery valves on the 82 300D Turbo. It appears to be leaking up through the threads of the delivery valve. I would like to at the very least replace the crush washer that sits in the bottom of that hole, but I can't find it on any of the parts sites. I actually wouldn't be against replacing the other parts of the delivery valve as well, but I would settle for the crush washer.

The dealer has no clue what part or part number I need.

Does anyone know where I can find these crush washers for the Delivery valve on my 82 300D Turbo?

Thanks.

no,

Your dealer must have a lousy parts man. I was always able to get these parts from my MB dealer.

Is there a Diesel injection service shop in your area? Look in the Yellow pages under: Engines, Diesel fuel injection service and parts. They should have or be able to get the parts U need.

Where abouts in PA are you? I am near Baltimore, MD. I have called a couple of places around here and they are total idiots. Do you know of someplace near you, I don't mind driving? Or have you ever dealt with anyone in my area?

This is really frustrating. The Diesel leak is so small, that I have been putting it off for a while, but the corresponding injector makes a kocking noise...almost like it is misfiring. But it is fine once the engine is warmed. This is a pretty simple fix, but finding the parts is the PITA about this job.

no,

I live in NE PA on the NY border, a long way from U.

I haven't done any business in your area so I'm no help there. Maybe if U go to one of the Diesel injection shops, they will help U. In an area as large a Baltimore, there should be at least one Diesel injection shop and maybe more.

EXCELLENT!...I will check them out.

I'd been told, and so far, I concur, that no crush washers are needed, just replace the O-rings. There's an EXCELLENT post on the wikki forum thing on how to do the job, by the maestro himself, jbach36, though it's for a W124. VERY helpful, and VERY thorough instructions ... if I don't mind saying so myself!

For the o-rings as well as the crush washers, http://catalog.peachparts.com/.
617-0109 is the splined socket necessary to torque down and remove the delivery valve.
Going to have to do this myself as soon as the o-rings and socket arrive, #1 delivery valve on my '87 300D is still leaking even after a week of not being driven.

What O rings, I think on that pump its just the delivery valve sealing rings, (crush washers) could you be thinking "Euro pump" or are there O rings I should have changed?

Also, I don't see these parts on ***************. Maybe I am not looking under the correct catagory, but I don't see them either under Diesel injection or the fuel delivery section for my 82.

Would it be one of these seal rings?

The US W123s IP doen'nt have "O" rings, The Euro cars do. I would call Phil or Rusty, they should have the sealing rings (crush washers) that go under the delivery valves.
