Any Deutz Experts Out There?

Welding man · Jul 25, 2021

Local contractor gave our antique tractor club a nice Bomag vibratory roller. He said it had an engine issue and he wasn't going to spend any money on it. One of his mechanics started working on it and got sick, is not in good health,may not ever be able to work again, so he gave it to us. They delivered it, it has a Deutz 1011F 2 Cyl engine. has a mechanical pump and injector for each cylinder. All of that had been pulled out along with the oil cooler and a few other pieces and was in a big cardboard box. I downloaded a very poor manual from the internet and lit in on it, putting the same shims back under the pumps that came out. After a hard days work, I have concluded that the fuel lift pump is very weak, the fuel shutoff solenoid is bad and the fuel rack is not moving as freely as it should. Other than all that I did get it to run. It starts decent, but is very rich ,like it is out of time or overfueling and has little or no throttle response. An help or suggestions appreciated. I know very little about these engines but I learning very quickly.

If the air intake system is off that would rule out restricted air flow causing black smoke. Another cause on some Deutz engines is injectors installed backwards, 1/2 turn off. I've seen that before on a Bobcat/Deutz application, the return line injector outlet must be toward the valve cover, if turned 1/2 engine will start harder, have little power, and smoke more too. All I can think of right now..

That engine is very common in none operator plant such as welders and site compressors, I had some contact with them but am more familiar with the larger ones that were fitted to the Poclain, Liebherr and Atles excavators, the rack must be free and be moved by your finger tip, if the rack is sticking the throttle as to speak is sticking, the pumps must be free too, by what you are saying about the over fuelling it sounds like injector nozzle not atomizing the fuel, have them tested, that engine has a timing belt, there are two special locking pins required to set the timing, read the manual about the timing and how to loosen and tighten the camshaft gear as it is not conventional, about the lift pump and shut off solenoid, turn the engine till the pump lever has pressure on it, operate the lever with the ignition off, open a bleeder there should be no fuel coming through, switch on and see if it does, if its not letting the fuel through then take it apart and clean it, the plunger may be sticking, see how you fare.
