Morning, Ray from TN here and this is post #1 for me and its a doozy. I'm a hotrodding , motorcycling, grass cutting grand pa. I'm new to the forum but not to life.
I have problem on my BX 2200 with 1050 hours, I cut grass with it mostly. I've had it ~11 years. The post is long because I've been battling this problem all season.
It runs good while cool but once it heats up it looses power. I have found numerous posts about this on the internet, but no real solution. I'm on the trail and just about got the issue corralled, I think...
You can hear it coming, at first you can hear the exhaust note change every once and a while. The tone then progresses to become more pronounced.
You start to notice your smelling exhaust and white smoke is coming out. Its very hard to see, you need a dark back ground or better eyes than I have to see it.
It then loses major power and shakes like its running out of gas but it won't completely die. You can get off of it and let it cool, then jump back on and it runs like a top again for 20 mins then repeats the above.
This is what I've done.
1. new kubota fuel filters and fresh fuel, plenty of fuel coming out of tank at first filter, line not stopped up and looks good. Fresh air filter.
2. Modified my gas cap to assure it was venting. I took the engine side cover off for easy access and to be able to watch the clear fuel filter.
3. New electric fuel pump, good fuel flow coming out at 2nd filter by injector pump on block. It ran good for 2 cuts, I thought problem was solved then it started again.
Against my better judgement I had bought a cheaper fuel pump, so I bought a better one and new filters. It still did it again, I took the line loose at engine while it was hot and running crappy and it had great flow.
4. I bled the lines at the injectors and at the injector pump, but it still did it.
5.I bled the lines 4 more times at the injectors and at the injector pump. I bled the lines again when the problem was going on at idle. I throttle up a little and bled it again and noticed the injector line closest to the radiator wasn't getting diesel like the first two.
You noticed the engine die down and pick up when you bled the 1st two injectors but on that third one had little change. So it was getting enough diesel to idle but not enough to support more throttle.
I'm not sure if diesel vapor locks?? When a injector pump goes out does it go out all at once or can it be intermittent at first?
The engine is not too hot. Radiator is full and is not losing fluid. No oil in coolant. The oil is clean and full, this should eliminate cracked head or bad head gasket.
6. I lost my cool a little and because I had vapor lock in my head I pulled it over to the water hose when it was running crappy and put a concentrated small stream on the injector pump and as it cooled it off you could hear the engine smooth out and regain normal operation. You could operate till it heats up and do it does it again. So I did this 3 or 4 times then thought ok, maybe engine is heating up so I cooled the other side of the block, which I know is not the smartest thing to do, and no change. I again concentrated stream on injector pump and it smoothed out.
So I think I need a new injector pump but that's a chunk of cheese to invest with out knowing for sure that's it. Hence me joining this forum to pick the brains of the Orange Tractors elite professors here on Orange Talk.
