OK very briefly the FSM says to set the crank shaft to begin of delivery (so that's 24 degrees BTDC for the MW/RSF pump). Replace the 'O' ring on the shaft of the pump. Set the shaft on the pump so that the missing tooth in the spline shaft is aligned with the mark on the pump. Fit the sleeve on the shaft and fit the IP.
The one thing that does concern me about swapping to a different pump is that as you are now fitting a MW/RSF pump it relies on the engine lubrication system for oil. IF YOU ORIGINALLY had the oldest type pump on the engine the engine lubrication system will not be compatible with the MW/RSF pump. It will probably seize. The oldest type pumps had their own lubrication system that was separate from the engine. EDIT:- I've just been checking on some of the MB parts sites I know about and I think the 616.939 engine was introduced in 1982 - which would mean that there is no way the older type IP was ever fitted to the engine so I'm probably fussing about nothing!

" Fussing about nothing "..... but bringing it up may help someone else when dealing with their pump....

616.939 was motor where i have take PES4M5SC320RS107-1 ( no itself lubrication)
But the motor which I have now on the car have used PES4M55C320RS60 (with itself lubrication). You are correct i can not fit newer IP on old motor. |

This is for the first front cylinder? Or for the 4. (last) cylinder? (4. cylinder taking in gas the 1. explodes) |

Can you clarify this? 1) You used to have a MW/RSF pump (PES4M55C320RS107-1) fitted to your OM616.939 2) ...but now you are trying to fit a MW pump (PES4M55C320RS60) to your OM616.939... 3) You have not changed the whole engine for another (?) If you are doing this and you don't have the separate venturi set up on the air intake manifold (and possibly some other stuff that was fitted to the oldest OM616's) then there is no way in which you'll get the engine to run properly. The oldest IPs use a differential vacuum pressure from the air intake manifold to the atmospheric pressure as a basis or reference point for the idle setting. Without the whole system (working correctly) you'll have an engine that idles at say 2000rpm+ when warm...

The timing is always set from the first cylinder - do you understand that the camshaft on a 4 stroke engine can be in two positions when the crank is positioned at TDC?

First cylinder must be in what mode?
1. in air (0* to 180*) 2. compresion (180* to 360*) 3. explosion (360* to 180*) 4. out air (180* to 360*) Paste 24* where it shoud be. |

You should be able to see a number stamped into the engine block just below the head gasket joint at the rear of the engine close to the IP and oil filter tower. If you can't find it try posting some good pictures of your engine as it is today in your truck.

As a rough check you will see a notch on the spacer on the camshaft that should be almost (but not quite) in line with a notch on the first camshaft tower. If this notch is at the bottom of the camshaft (underneath) then you've got the "wrong" TDC

Machine numbers:616 934 10 119 367 ( made by hand)
and on motor body 616 011 28 01 (this is same for both motors) |

Is attached picture correct?

The four stroke cycle means that the piston will be at the top of the stroke TWICE in the cycle ( 360 degrees TWICE means 720 degrees in one cycle).... so the ' wrong' TDC ( which looks EACTLY THE SAME LOOKING AT THE CRANK markings ) means the next time THAT piston comes to the top of the bore will be the correct measurement time...in relationship to the injection pump.

Looks good to me - just like in the picture on the wiki
The numbers at the bottom of this picture are for BEFORE TDC But like I mentioned before you need to make sure that the camshaft is also at the right place - so that is in step 2 - looking through the oil filler hole Alternatively with the valve cover off of the engine you can see the marks on the camshaft tower and the close proximity of the notch on the camshaft spacer...

There are also many many explanations out there such as Four-stroke engine - Wikipedia, the free encyclopedia
