I'm having trouble keeping my tractor idling, it has the gear driven pump on the right side of the motor. If I add motor oil into the hole it does better for awhile but I have had this tractor for over 15 yrs and I thought the fuel pump gear box was fed oil from the motor sump, is this not correct? Forgot to mention its a Ford 5000, not real sure about the year but its the 8 speed model it was running great....

Hi 60shazbot, welcome to the forum!

Later 5000 does not have the breather cap (Minimec pump).
The picture was stolen from this User Manual:

Looks like the 5000's were produced for 15 years between 1964 to 1979. Yours could be 43 - 58 years old, roughly.
Plenty of time to dry or wear out o-rings a plenty. Also, looks like your fuel injector pump has it's own lubrication, separate from the engine oil.
I just pulled down a fuel delivery system in a 50yr old Kubota that could barely run, sometimes. I replaced all the o-rings, it purrrrrrs like new and I didn't alter timing a bit.
So a thought.....maybe just an o-ring leak. There are a number of ways to isolate a leak but, if you find one rat.....

Check the drain and FULL plugs..
They are normally self contained units, meaning u HAVE TO PUT OIL IN THEM, check them and change the oil at least once a year..

I would remove the cap and see oil about half up the gears so I left it alone when I first started having running problems I checked it and couldn't see any but I also didn't see any oil leaks so I added oil to the half way mark, after doing this a few times I wondered where the oil was going so I pulled my oil dipstick and it was past the full mark, is there supposed to be a barrier in the pump housing that keeps the oil inside the fuel pump??? It will crank up but within minutes start running real rough, if I increase the throttle to keep it running it throws out black smoke along with the rough idle, if I put the throttle back into the idle posistion it immediately cuts off...

I don’t know what u mean by taking off the cap.??
The FULL LEVEL is on the side of the pump.. it takes a 1/2” wrench..
It sounds like u have a FUEL RESTRICTION or starvation problem..
FP314A is the supply pump p number IF it’s bolted to the side of the pump..

is there a steel line that feeds oil into the pump body.?? If yes, the oil comes from the engine & drains back thru the front of the pump..
If no, u have add oil and there’s a front seal that holds it inside the pump..

Hey thepumpguysc,
Is it possible he has a Lehman or Dover engine replacement? They were engine fed pumps.
60shazbot, I think a pic is overdue.

 

[thepumpguysc]

I agree.. at least a nod one way or the other on the SIMMS pump picture.

Ford 5000 with an eight-speed transmission points to a Ford 5000 from the 1000-series (1964-1975). A "Lehman or Dover" (D4 or 27xx engines) can not be fitted into a 5000 (1964-1975), at least not without rebuilding most of the tractor.

Unfortunately, Ford decided to change the Fordson New Performance Super Major (1962-1964) name to "Ford 5000 Diesel" for units exported to the US, which is confusing. Only six-speed transmissions, but those can have a D4 or 27xx engine. Anyhow, here is what the possible injection pumps look like, hoping for some type of reaction:

Yeah, my pump doesn't look anything like the one in the pic-I'll get my son to help me post a photo of it-I can turn a wrench on most anything but most of the digital phone stuff is over my head.LOL...

Later 5000 (~1972-1975) had a CAV DPA type injection pump. Diesel fuel lubricated, no extra oil filling or engine oil lubrication.

Does this mean we've reached the end of "Guessing FIP Game" ?

 

[thepumpguysc]

Not yet.. at least we know it’s NOT a Simms pump..

 

[2billt]

True, 3 lubrication types are now posted, I think we ran out of guessing options from that standpoint.
A pic is worth.......???

"it throws out black smoke"
Can you theorize the reaction of a Lucas CAV filled with engine oil?

 

[thepumpguysc]

It will just get flushed back to the tank..
Depending on how much fuel is in the tank, it might get mixed with the fuel and cause a problem..
But I don’t see that happening..

So far, pressing the camera trigger has been the hardest part of this topic.

 

[thepumpguysc]

Lol.. ALL pumps have name plates on them..
Do not scratch it.. if u have some EZ OFF oven cleaner under the sink..
.. use it ..
