Help: Kubota B6200E died, now not starting

keljan11 · Apr 23, 2019

Hi all, newbie to the Kubota forum.

I have an older B6200E Kubota I inherited from my father in law about 8 years ago. It was used pretty regularly when he had it, mowing between the rows of Christmas trees. As we no longer have the trees, it has been pretty much just sitting, used occasionally maybe 5-10 hrs a year since I've owned it. It has 743.9 hrs at the moment.

So, a few days ago, installed the battery, started it up, and all was good. Moved it to where I needed it, when it sort of coughed a bit, then stalled. Tried starting it again, no go. Figured the way it stalled it was a plugged fuel filter (haven't changed it in a few years). Got a new filter installed, filled the filter, tightened it in, bleed the injector lines, tried starting, nothing. Turns over fine, but won't fire. Checked to see if there was power to the glow plugs, there is. Noticed the first injector line had lots of fuel leaking, nothing out of the middle injector, and bubbles out of the 3rd one then all fuel . Tried bleeding several times.

Any suggestions out there??

Is it the return from the injectors that leaks? Any leaks on the fuel system is potentially a show stopper. Old fuel?

Sorry, guess I didn't explain myself. There are no leaks. It was while I was bleeding the injectors. There was diesel at the 1st and 3rd injectors (while bleeding the air from the fuel filter change-out). No leaks once I tightened the injector nuts.

Yes, the fuel is from last summer, but I always use diesel conditioner when storing it for winter. Will drain the tank and put in new diesel, bleed the injectors, and try again (tomorrow???). Will post results if there are any.
Sorry.

Bleeded the injection pump? Good flow from the tank? If the fuel is just a year old I'd let it be, should not be an issue.

Thought this all sounded too familiar.

Some of this smaller Kubota's have a bleed point on the injection pump.

Bleed with throttle wide open. After bleeding pump, then one injector at a time.

Since it turns over, a open safety switches shouldn't be the problem. I diesel basically needs just two things, air and fuel. It's likely not a plugged air filter but just the same I'd take it off and inspect it if only to rule out the filter. That then leaves no fuel. As DaveM7040 says air in the lines is the likely culprit.

Problem is solved as posted on the orange forum

He was not bleeding the pump.
