See the Pic showing the O-ring (at the base of the red arrow) that goes in an internal groove in the Pin Bore. The One without the Roller also has an O-ring in there.

The one you got from Phil is the one I have pictured and Mercedes sells it as a Valve Kit. And, that kit comes without the 30mm Plug Gasket and no O-ring.

When I did Mine I got the Right sized O-ring from a Local BMW Dealer and I simply put a gasket sealer on the threads at the base of the Plug and left the Copper Crush Washer Alone.

Mercedes sels the 30mm Plug Crush Washer as a seperate part.

One of our Members in another thread came up with the Mercedes O-ring part and He said they are now Viton.


If you want the complete Kit in one of the Threads one of our Members bought that kit from a Bosch Fuel Injection Shop.

Thanks for posting this



The "turbo" lift pump parts do look different.

Do you happen to know if the lift pumps fitted to the non turbo MW IPs were the same as the turbo versions? Or is it more complicated than just a difference between M / RSF and MW pumps?

Here's a picture of a "MW" lift pump I've got





This is a MW IP that was fitted to an early OM617 / 300D

Stretch - What are the 2 types of IP pumps you have posted - year of car and pump type?

First IP picture has that rectangular brass colored access port (?) and what i will call the newer fuel/lift pump with 3 holes on top, while the second IP picture has the lift pump with fuel inlet port on right side of fuel/lift pump.

Are the roller bearings associated with non turbos or type of pump?

Thanks

Chris

The partly taken apart one is from My Turboed 300d and off of an MW Pump.

The M pumps have the 2 holed Flange and look like the one this thread was about.

After that my experience is too limited. I only have My own Vehicle and what I read on the various forums.

When I worked in the Fuel Injection Shop about 1975-1980 all of the Bosch Lift Pumps I can remember had the Roller Tappet in them. But, the Pumps I saw were mosly for truck applications or the Older Mercedes Cars and Thermokings with Mercedes Engines.
The Mercedes Diesel Cars made in 1975-1980 that had any Fuel Injection or Lift Pump issues would have been taken care of under the Mercedes Warranty. Meaning that I would never have seen those Pumps in the Shop Where I worked.

Didn't know the roller bearing section was serviceable or about the o-ring location.

Just finished tearing down my extra pump...thanks for showing the exploded view of the roller section. Now to chase down 2 more parts.


I didn't find ANY of the 3 o-rings shown above during my tear down. I did locate the small o-ring, 003 997 82 45, in my rebuild kit. Do i need the other 2 o-rings Stretch shows or just the crush washers?

Does the small o-ring just sit on the shaft during reassembly?
How do i extract the piston, toward the roller bearing or towards the 30mm plug? After looking at the cylinder section with better light i see a stepped section on the roller side preventing travel so towards the plug, right?

The little O-ring is the only O-ring on the Turbo MW type Lift Pump that uses the Kit I posted the pic of with the hard Plastic T Valve in it (turbo MW Fuel Injection Pump).

Ask Stretch to be sure but I am guessing the 2 larger O-rings are used on the Lift Pump that has the Disc Valves like the one this thread is about (Valves similar to the Valves in the Vacuum Pump).

FYI... Thanks for the picture of the rebuild kit as my local dealer was having trouble sourcing one for me!!! I wish I had found this thread a week ago, it would have saved me a lot of trouble. I did end up finding a Bosch gasket kit that seems to be for all the FP/K feed pumps. It has all the parts shown in the rebuild kit and more. including the 30mm washers.

If you still have it how about posting the Bosch Kit part number and how much the kit cost.

Also there is other threads that have the same info posted in this thread on the Valve Kit.

Stretch, can you easily source a good working or rebuilt lift pump like this one, for the M- injection pump on a euro spec 617 NA?
If so please PM a cost and shipping to USA if possible

I can do an advert locally for you to see if I get any takers. They don't come up for sale that often. I don't "do a Charlie" and visit yards as mostly they're a waste of time over here.

Is your Fuel Injection Pump missing the Fuel Supply/Lift Pump?

If your Fuel Supply/Lift Pump is not missing or damaged there is a rebuild kit for it.

I forgot to mention if you look in the non turbo FSM chapter 07-001 there's a list of lift pumps fitted to IPs and engines. Some of the OM616 M pumps look quite similar and probably made it to the US of A

The M Pump Fuel Supply/Lift Pumps have Disc Valves in side instead of the Solid Plastic sort of T shaped cylindirical Valves with separate Springs that are on the MW Fuel Supply/Lift Pumpumps and the Hand Primer is on a different spot on the Body of the Pump.
I thin the M Pumps Fuel Supply/Lfit Pumps also use only 2 studs or bolts to hold them to the Fuel Injection Pump; the MW uses 3 studs or bolts.

Indeed - pictures on the first page show two bolts (slightly bent)

Refreshing an older thread ...

Does anyone know where one can buy the kit for the NA ("M") styled pump (it has a fastner on the L&R sides and not 3 (in the shape of a triangle -- sort of). I've looked a bunch and no dice ... Thanks in advance.
