- 2004 New Holland TC40DA w/hydrostatic transmission & 4wd; 1983, MF 230
This 1983 Massey Ferguson 230, w/Perkins diesel, was running well while bush hogging; then, began to seem to lose power and quickly die. I changed the fuel filter, checked for clean fuel & good fuel flow from tank and "all" lines, bled (hopefully) air from fuel lines -- but it still has these same symptoms:
It almost always requires spray starting fluid to start. It has started twice (out of around 25 to 30 attempts) w/o the starting fluid. It will idle -- or rev -- normally for a couple of minutes, or as long as 20 minutes or so, as smooth as silk... but then: will ping or knock and/or rev a bit (as if ether had been injected) and then idle again, then continue to repeat this at closer intervals until it finally seems to lose power(fuel?) and goes dead. It will even operate as usual for a very few minutes and then just seem like it runs out of fuel (when under a load).
I did think that I may have put old fuel with water in the tank just before this began happening -- but have not seen the first sign of water in any fuel throughout the system -- and, did put some "Seafoam" in the tank to try and counter any adverse reactions for that possibility. Could the additive have loosened something that is clogging the injector pump???
It just recently had a new alternator, battery, and starter installed; and the fuel injector pump was completely rebuilt ($500!) about 3 years ago.
I get a steady stream of fuel from the tank petcock valve, so I don't think the screen inside is clogged. I also get a steady stream of pure, clean fuel from any line I disconnect or loosen "anywhere" in the system, so it doesn't seem like air lock.
Does any of this sound familiar to anyone? I have been told that it "must either be sucking air somewhere, or the pump is going out." Was also told to "smell the engine oil to see if it smells like diesel -- if so, the seal is blown and will have to be replaced." Has anyone done this repair? I don't even know what/where the seal is they are talking about. Is it a "do-able" job for the average Joe?
I just wondered if anyone from the forum may have encountered such a situation and if so, what was your "cure?"
Any help is GREATLY appreciated.
