Ford 5000 Fuel Screw

Heagon · Nov 17, 2020

Good Evening Gentleman,
I have what I thought was a ford 7200, but turns out to be a 5200. No turbo on it currently, was sometime in the past. I am thinking someone has turned up the fuel screw on the injector pump, it will pour black smoke when pulling. Is there anyway to tell if the screw is in the stock position? I was wanting to add a turbo but am afraid if its turned up too far Ill be searching for a new engine soon. Attached a pic of the screw if that helps.
Thanks

Looks like someone backed out the max fuel screw all the
way. Turn it back in, until exhaust smoke is a light haze under
heavy acceleration and/or heavy load. Heavy black smoke
just wastes fuel on non turbo engines.

So it is fully out? If one was to put a turbo in in the current condition would it quickly blow the motor?

The way to tell if it is fully out is to loosen the locknut and see if you can thread the adjusting screw out
(counterclockwise) any further than it already is. If not, then it is turned up all the way, and is the reason for the black
smoke.

If you decide to put a turbo on it, and don't do something with the fuel setting, you will melt that engine down in short
order.

Thanks for the info bern. So would the engine without a turbo make any more power with the screw out, than with it in its stock position? Or is it just making it smoke? Thanks

You say it had a turbo in the past, so is it a 5200 or a 7200 with not turbo.
List the model codes to find out what you have.
The 7000 engine uses different internal components to help it handle the added air a turbo puts into the cylinders.

Regardless turn the fuel screw in to reduce smoke and wasted fuel.

The model code is E2014C, all the other numbers on the hood match up, so what I thought was a 7200 is 5200. All I do with it is rake and occasionally roll some hay, so Im still interested in possibly adding a turbo kit to play with it. Im DEFINITELY turning the fuel screw down, its like a train under load. Is the stock setting all the way down, and one full turn out?

The only way to find the stock setting is by taking the pump off and sending it to a pump shop. Alternatively, you could put
the tractor on a dyno and adjust the fuel setting to the rated HP. This assumes the engine is otherwise in good condition.

If you don't wish to do either of these, turn the fuel screw way in until you notice a lack of HP and no smoke under load.
Then maybe give it a wee bit more (by turning out). You should only see a slight gray haze of black smoke at full load.

Increasing fuel without a turbo is only very marginally effective at increasing power because very little additional fuel will actually burn without the addition of more air.

Thanks for all the info everyone, Im going to turn the screw down so it wont be pouring smoke.
