No idea where to go next with this thing.It has the 3 cylinder diesel with the CAV injector pump.
I replaced the fuel filter on it, re-primed and got it to crank. Running great. So I take off to start cutting a field and in the middle of the 3rd pass it drops power and dies about a minute later. I re-fire it and it will only run for about 45 seconds to a minute before dying again. I get tired on messing with it for the day and tow it back to the shed. I wasn"t able to get back to it for about a month.
I assumed there was some type of trash blocking the flow so I started with the small line filter screen on the side of the pump, it was full of crude. Next I remove and check the fuel filter that I had just replaced a month earlier with only about 30 minutes of run time on it. It was about 75% full of WATER. So it got replaced again. Drained the fuel tank and it had about a gallon of WATER in it. Cleaned the screen filter in bottom of tank, flushed tank, and blew dry with an air compressor. Also blew out all the lines going from pump to tank.
Refill the tank with clean diesel and go through the priming process.So this is where the questions come in since I don"t really know how it is IDEALLY supposed to be as far as fuel pressure goes.
When you loosen the primer screw on the pump, is the fuel supposed to be squirting out a strong stream or just a constant weak flow?
When you take the fuel line off the injector, should the fuel be a strong squirt or steady drip?
What will water do to a pump if it gets into the fuel system?
We got the system primed with all the air out, but couldn"t get it to fire. So after several attempts we decided to pull it around for a bit. It finally fired! However at FULL THROTTLE it wouldn"t rev any higher than 1200 rpm. We let it set there and idle for roughly 10 minutes before it died. We pulled it off again just to park it back under the shed. Same result. Ran a few minutes at a 1200 rpm max and then died again.
We are thinking the pump maybe bad. Pump was supposedly just rebuilt before we bought the tractor a year ago. Open to any ideas at this point.
thanks in advance
