3038e keeps dying

[jasonlebleu]

Hello all,

Enthusiastic newbie with a 2012 3038e that is absolutely amazing. I'm using it to clear a future homestead and its perfect for removing saplings and grading the washboard effect out from under reforested pines. I have a fantastic dealer that sold it to me, too. Just one annoyance that neither of us have been able to crack the code on though- After a little use, it will just die and I have to set everything back out of engagement and then crank it twice. The first time it will just crank or crank and fire momentarily and die again. The second time it will fire off and I'm back at it for just enough time for me to forget about it and then it will happen again. It was suggested that it was the seat cutout, but I've ruled that out because it will also happen if I leave it running disengaged to jump off and do something else for a moment or two. The auto primer circuit is clicking away nicely when this is happening, so It just seems like a fuel flow issue, but before I start getting into things myself because that's what I do in these situations, I wanted to ask the voices of experience out there.

Details that may matter:

bought with 186 hrs
now at 220 hrs
There was mention by the dealer of water intrusion in the tank that was apparently dealt with before the sale
I've drained the white plastic fuel bowl/access port on the right lower side of the engine multiple times


As I type it makes me want to drain the tank and confirm for myself that there's no more water, but that aside, any other thoughts?

Thanks, Jason

My first thought is a foreign object in the tank. Perhaps a dead insect that momentarily closed off the tank outlet but then jiggles off to allow fuel flow.

Thanks! That makes sense. I'll check that first thing, as well as a suggestion to see if the fuel cap vent is plugged, also causing a flow change due to vacuum. I'll report back on those.

Jason,

Read these threads. The problem is more common than the forum would indicate because the posts are scattered among many sub-forums and you wouldn't pick up on it easy. I've had the same problem TWICE on same tractor over a period of years, and on a bulldozer many years ago.

Thanks folks. My money is now on some sort of debris because its just like those folks said- could be a few minutes, could be 3 hours. Also, if I wait a while, it may start better- or not and it may not do it again for a long while- or not. More to follow...

Update?

 

[jasonlebleu]

Well, it's not the fuel cap and I haven't been able to spot anything in the tank. That said, I can't see in there well at all, so I'm running the fuel down and plan to pull the tank this weekend.

You might want to rig a light in the power side wire going to the fuel shutoff. That would indicate power interuption which would cause a problem like yours.
If the light goes off while the switch is on you have a problem.

I ended up with it back at the dealer for an unrelated issue and they dug into this problem, too. Haven't gotten it back yet, but they said that the port at the bottom of the tank was all but blocked with debris, so I'm buying that for a dollar until I get to ops check it.

Please report back the final resolution.
