JD 6220SE randomly cutting out

[Muck Spreader]

I've mentioned this problem before, and thought we has sorted it 18 months ago but it has now returned. Pipes, filters, filter housings all replaced injection pump overhauled (Stanadyne DE10). The tractor can run for many hours with no problem then suddenly out of the blue will start to run erratically and stall. Give it 30secs and it can often start and run if nothing has happened or it can mess about for a while before settling down. Wondering if I should look at changing the 3 sensors that relate to the injection pump (crankshaft, temp, oil pressure) and maybe the fuel pump?

If you undo the fuel cap is there a vacuum?

Certainly get shut .

Presume the electric fuel pumps fine or you would have said
My 62 had problem with its pump but it was bad connections at battery that wasn’t the pump to run right

It is one thing I am thinking of changing. It always appears OK but I am wondering if certain conditions cause it to momentarily airlock or something. IMO it's poor design where the pump has to pull fuel all the way from the tank and though the primary filter and then push the fuel though the secondary filter to the injection pump.

You could change that, so it pulls to pump, then push to first filter, did it on my 68. lots easier to bleed!

Just copied this off a post ,About a kubota loader from tsmith 0998 Fuel issues . We had some issues with one tractor with fuel issues everything was changed by the dealer .Still could not sort it out ,so I went back to basic mechanics Starting with the fuel tank no issues in the tank ,but the pipe from the top of the tank to the filters i’ve been cable tied to a Steel hydraulic pipe a little tight ,and when everything got hot it started to break down the rubber pipe collapsing inside causing loads of problems just a basic engineering mechanics from a little farmer sorted it all out .must’ve cost thousands under warranty all the replacement items and loan tractor was given to us. The post was from me.

First thing to check is that you’ve not got debris floating in the fuel tank. Any debris can momentarily block the suction intake in the tank- tractor stops- debris floats away again- repeat.... seen this before. You’re got to check fuel supply Is consistent before worrying about sensors etc.

Don’t there’s many farmers that haven’t had junk in the tank at some point. We had one kiddy that left the cap off a 956 and it got loaded by the forager. It was a nightmare to clean out so took out the bung and pressure washed it. Let it dry and pumped diesel in a loop through a filter. Still didn’t get it clean even then so has a plastic filter in the line and just swap it out every now and again.
I guess the grass binds together as it attracts moisture.

I had the same problem with my 6220SE. Main dealer and independent repairer suspected the injection pump. I did replace the fuel pump as the commutator was completely worn out, but that didn't solve the problem. Eventually I traced it to the rubber hose between the tank and primary fuel filter being perished and drawing air. The tank was often pressurised when I removed the cap. I changed that hose and the problem has not re-appeared in over 6 months. When I replaced the hose, I used a bio-diesel resistant one from a hose specialist at 20% of the cost of a genuine part.

Now Then..
I assume the suction screen in the tank is clean,, hoses in good condition, Bosch transfer pump fitted and hosed correctly with the restrictor in place along the hose to the leak off line??
Have you checked for error codes??
Of all the controllers that John Deere use, that one is the most prone to failure and the symptoms you have. I've replaced many and keep one in the van for diagnostics..

Yep we do the same with ours. Remove suction screen from the tank and run with an easily visible and serviceable inline strainer.

I noticed one small pipe still looks like an original JD fabric one that goes between the secondary filter and the return from the fuel cooler possible problem?

It's been checked out in the past by the dealer very limited as to what they can diagnose on an SE. I gather you have to buy the ECU even if it still fails to cure the problem.

It worked all day yesterday straw carting without any problems. Did swap fuel caps over with our other JD.

You only want to worry about the fuel lines between the tank and the pump. If they deteriorate they can suck air and cause problems. After the pump they are generally under pressure and any leaks will be external and obvious. Don’t change anything until you’ve determined the hoses from tank to lift pump are good and the fuel flow from the tank is also good, ie no blockages as per posts above

I'll go and hide now.

Funnily enough I was in the Insurance office only a couple of weeks ago and they actually commented on the fact we rarely claim for anything and had not even had a tractor going on fire.

Wouldn't it be bizarre then if you welded something on the back of the tractor and accidentally fried the engine controller, or some inexperienced person tipped fuel from a part full dairy chemical drum into the tractor and damaged the injection pump.. It sounds like your way too careful for such accidents..

 

[haybob]

I have a 6220se and it also cut out while I was driving up a hill. Fuel was low but not on red mark. My mechanic friend said mine was probably air or a bit of muck. Maybe you have similar prob?

 

[Tractortech]

They still run with this much rubbish on the suction screen.. I was replacing all the fuel hoses and had the opportunity to remove and inspect this... Glad I did.
So,,,, if you have any issues, start at the beginning, eh..

Recently sold my 6220 se 04 plate, but about a year ago it would erraticly stall and was eventually diagnosed with a faulty ecu. New ecu and that cured it.
