First off, I hope everyone had a great Easter !! Got out to the farm today for Easter dinner with the family myself and after the dinner and egg hunt for grand daughtr and assorted nephews, I went up to fire-up the hibernating engines; 180 gasser,XT 190 and the F2. Combine fired right up(we hit 69*today ) and ran for 15 seconds and died. We have been having this issue for going on 2 seasons now but it will start fine unless it sits for a month or 2. On a hunch, I climbed up and attempted to pump the primer and pretty sure I discovered the problem-the primer leaks like a sieve!! I did get it started as well as the 2 others started and looked up a part # for a seal in the primer but the parts book says we need a 3 piece combo? Part # 74063231?
I googled that # and saw it wasn't horribly expensive in the grand scheme of parts $$ but was just surprised there just isn't a simple seal. One of the "vendors" stated that the above # has been updated ?? |

My F2 and 220 do the same. Long time parked you better pump primer first if you want it to stay running
. Put new primer assembly on 220,didn't change it. Just pump the the primer and move on. Mine don't have the external leaks but something is off. |

My 860 cotton stripper has the 2800 engine, and I have the same problem. I tried to use mine last season, and it just sprays out around the primer pump plunger when I pump it, and has no resistance at all. I was actually about to post about it, but I'm glad you did. I'll be interested to see a solution.
I looked in the 860 parts book, and it just shows the primer assembly, which I found for sale here for $250, But after looking up your part number, it seems like that plunger with the seal might fix my problem, even though that piece by itself isn't listed in the parts book for my machine. Surely the pumps aren't that much different on the 2 engines, being as they are probably about the same age.

That is EXACTLY the symptoms-sprayed every where but was able to feel "some" resistance. Got it fired up though,just didn't care for the 10-15 seconds of cranking, usually(and it will now) pop off within a rev and a half of cranking.

Right, my 2800 always starts just as soon as you hit the key, unless like you said, it's been sitting a while. When I tried to prime mine, it didn't do any good, just made a mess, and I still had to crank on and off for a long time, which I didn't like.

If you’re primer is like a 185 tractors, you can buy the rod with both the primer seal and seal for rod which stops the fuel leaking out. My son just got 1 from Willian Equipment in Charlotte MI for right at 40 dollars, about 30 bucks cheaper than the pump guys could sell one for.

Old,they are the same part #'s LOL!! Like I said, not outrageously priced, just surprised an individual seal can't be had.

Freedguy, sounds like your problem is return fitting in top o pump is plugged with rubber from governed flex ring coming apart. Time for a pump rebuild.
Needing primed after setting is the check valves inside the primer, not the seals that squirt fuel on you when trying to prime it. MACK |

I replaced my primer on my XT due to a leak. Appeared to be the original primer although I cant confirm. New Agco primer works well. I never looked into a rebuild kit. Primer should only be used due to a fuel filter change or the tank is out of fuel. There are other issues if it has to be used other than that. My XT has set for 3 months before and fires right up.

Thanks Mack, the pump was rebuilt less than 150 hours ago for that very problem, our mechanic wouldn't let us pop the glass ball out though, told us to remove the line and remove debris on "as needed basis". It was a LOOOONG harvest that fall!!

So the fuel pump needs rebuilt you're saying?
Also, Freedguy, what do you mean by the "glass ball? I don't know much about diesels. Edited by CrestonM - 21 Apr 2019 at 9:43pm |

Are the check valves something that can be done by a do-it-yourselfer with basic tools or are there special tools/torque specs involved? Thanks

Mack is referring to the main pump that has an internal plastic part that disintegrates inside of the pump and sends black plastic pieces up the fuel lines. I think the pieces are too big to enter the injectors so they end up in the return line that has a glass ball in a fitting that acts as a check valve(I think). Once the plastic pieces obstruct the ball, the engine coughs,labors,SMOKES like crazy and finally dies. It won't restart until the plastic chunks are removed. That's my understanding of the issue,hopefully one or more pro's can explain better !

That is very interesting… My engine smoked like a freight train at the beginning of the season, but only at full throttle. Any less than that and it quit. But it was blue smoke though, so that would be oil, not fuel. After a day or two, the smoke went away completely. I think that’s a whole other issue though, not related to this fuel pump. The engine always runs great. Of course, now that I say that, it will probably start doing as you say, coughing and laboring. Haha Edited by CrestonM - 21 Apr 2019 at 10:19pm |

When the weight retainer comes apart, they pull down then die. After pressure drops in pump, they will fire back up. MACK

Mack, what is the "weight retainer"? I'm trying to better visualize this all, and have been studying the pump page of the parts book, but don't see anything like that. Maybe Agco has another name for it?

Just an FYI these primer assemblies are RoosaMaster/Stanadyne. So if your local pump shop can get parts, may be an alternative to Agco dealer if they don't have. If your injection pump was just rebuilt, I wonder if your return line got blown out? The primer assy is very easy to rebuild if you get all the internal parts.

I replaced my hand primer and filter with an electric pump and dual filter setup -works great, better filtering and no more leaks. Did that to my 190XT and 7060, also installed a check valve in the fuel line.
