Dieselmeken shows how to fix leaking pump
Dieselmeken shows how to fix leaking pump
This is a small clip showing how you can do to fix leaking deliveryvalveholders while the pump is still in the car.
Take care if you planning to do this operation

I just did that on my 300sdl but I did it one cylinder/delivery valve at a time
Dieselmeken,
thanks for the great videos!
would love to see a MB "M" pump complete disassemble reassemble
video explaining along the way.
for too many people the inside of injection pumps is a complete mystery.
I for one really appreciate your contribution to the community
keep up the good work!
Thank you goran. I don't know how you do it working and operating a camera

thanks again, I need to change a d-valve also (because my car shakes a lot after complete rebuilt),not only
copper washers,..so I have to let bosch guys do it..?
cheers
before going into the ip first check the injectors.
Compression is o.k.?
Valve job done?
Depending on what you define "shaking" you might want to search for damper screw (on the back cover of the ip).
Where from Europe are you?

hi tomnik,
engine has been rebuilt 15 days ago
compr/valve is ok, 5 injectors pop at 125-127 bar,...
yes,I have ordered rack dumper still waiting to come...
(is it possible to change it without taking oil filt.housing off?)
but few days before rebuilt I have taken pump to some bosch guys
and they told me that my elements are worn a bit, and in some
near future I have to change them ... do you or Goran have any
experience with DTP MW elements (made in Germany??) over here I can
get them 40e a piece ???
and my d-valves also had to be changed ....
btw I'm from Serbia ...

Hi,
rack damper can be changed with all in place.
Are you sure you can get the small MW elements 1 418 414 001 from DTP?
Your Bosch guy, can you trust him?
There must be much to wear a diesel pump element (if fuel filter was in use and not too much red diesel was used).
Are you sure that he can not adjust the balance of the elements?
Take the pump back and install it. Then you turn the flange of cylinder 5 until idle is better.
Wait until larger MW elements are available (6 months).

Its not so that you have missed the overflowvalve so that you dont have any pressure in the pump? seems quite odd that the pump would bee worse after a test & adjust in the Boschshop.
Have you timed the pump correct? Dont turn the barrel if you are not sure that you have the fault there.
Do you have a turboengine and need aalot of power? If not you dont need any bigger elements, you just need a proper adjustment.
Is the engine ok timed in crankshaft / camshaft?

To mee it sounds like a balance problem. It runs on all 5 cylinders what I can hear. Maybee Tom has another opinion.

I agree with Göran- balancing.
(I mixed up the cyl. 5 issue with another post).
Assuming that the pump has to go to a diesel shop for proper adjustment anyway, you could measure the glow plug voltage OUTPUT when the engine is running and the glow plug common socket is disconnected.
In the socket (where the it goes into the glow plug relais) you can take the voltage (mV only) and compare the individual cylinders among each other.
Then you carefully rotate the flange of the cylinder with lowest voltage.
The other voltages will then change also but in general it should be better than before.
This is not according to any correct instruction but can help.
Can you check timing with a strobe lamp at a Bosch service to confirm what the guys did?

I have to do some more tests but the MW elements will be >6.5mm.
