    Deutz Agrolux 60 (SAME 1000 engine) problems

    Zimmerman's Equipment in New Castle. Nice enough folks... it just seemed they were in a bit over their heads, or maybe just too busy doing easy maintenance work that doesn't require troubleshooting. I'm annoyed it took them six months to not fix it, but as they waived all the labor charges I...

    Deutz Agrolux 60 (SAME 1000 engine) problems

    Wow, over a year since I updated... got busy with other things, and the tractor worked well enough to lift things with the loader (which is most of what I use it for) so I put off doing anything about the problem. I did buy an injector pop tester, and they seemed to all test and spray OK. In...

    No bubbles in fuel coming out of lift pump... no bubbles in fuel coming out of filter... no significant fuel pressure drop after filter. Ordered an injector pop tester so that'll be my next step.

    Deutz Agrolux 60 (SAME 1000 engine) problems

    I started it yesterday to show the neighbor what it's doing, without the metal filter in the glass bowl... with the filter removed, nearly all the cavitation and air gap at the top of the bowl goes away. Just an occasional tiny bubble in the incoming fuel, that seems normal for any fuel system...

    Deutz Agrolux 60 (SAME 1000 engine) problems

    Sorry, I've neglected this thread, and the Deutz as well... had other stuff to attend to and needed a break from a project that has so far made no progress. I'm planning to test the fuel pressure post-filter, and also insert some clear line to see if the lift pump is producing any air. I'll...

    Deutz Agrolux 60 (SAME 1000 engine) problems

    There's no return line from the injectors. Fuel returns to the tank right from the pumps, with a check valve in that line. The valve seemed to be working properly when I blew through it. I replaced the return hose when I did the main hose, as they both run in the same hard-to-reach place between...

    Deutz Agrolux 60 (SAME 1000 engine) problems

    That's what I'm thinking too. My only other thought was that maybe a leaking injector is flooding a cylinder at higher RPMs. Timing could be a governor fault, or low pressure at a pump, or a faulty injector... anything I'm missing? I don't see how it could have jumped time entirely, as it runs...

    It's a 3 cylinder. The white smoke is definitely fuel (burns your eyes). I pressure tested the cooling system and the only leak I could find was a very very minor weep around one of the copper injector bushes. No signs of combustion in the coolant, or coolant in the oil.

    Reading back over this, I notice that the rough running commences at 0:28 in both videos... I didn't plan that.

    Couple more videos. There's white smoke right from the start in the exhaust one, because its 20 degrees F outside. But you can see at 0:28 where the engine speed dips and it starts the white fuel smoke. Same in this one, of the tach... you can see where the engine speed dips at 0:28. Also...

    Deutz Agrolux 60 (SAME 1000 engine) problems

    No time to work on it yesterday. I assembled a better pressure testing setup today, putting the gauge inline (with a snubber) between the lift pump output and the main fuel filter. 4-5 PSI at idle, 25 or so at PTO speed. Any change in pressure when it starts to smoke and run rough is very small...

    Deutz Agrolux 60 (SAME 1000 engine) problems

    Only checked fuel pressure at idle, but will hook it back up and see if there's any change when the engine starts running rough. Haven't worked the tractor very hard since the problem started (just pushing a little snow is all) but I've been keeping it in the heated shop at about 60 degrees. I'm...

    Deutz Agrolux 60 (SAME 1000 engine) problems

    I will try that. My thought is that air in the fuel could cause the injectors to fire late (because it compresses) which would be the same as retarding the timing, causing an incomplete burn. Willing to listen to any ideas at this point!

    Agreed. The bronze washer industry lobbied to have that put in, I suspect. SAME also thoughtfully blasted the entire engine, post assembly, with a shade of gray akin to the Death Star. Makes locating leaks and small components a real joy.

    Deutz Agrolux 60 (SAME 1000 engine) problems

    Fuel still going through lift pump, yes. From tank to solenoid to lift pump to main filter, back through solenoid and on to injection pumps. I will try to do more bypassing with clear hose, to see if bubbles appear anywhere in that path, but the banjo fittings make that more of a pain. Only...
