4000 diesel won?t run

Brother bought a 4000 diesel a couple months ago
and it died He put new filters on and bled it out but
it won?t run. My question is it has two lines coming
off the front of the filter housing to the inj pump.
Both have arrows on the filter housing indicating
flow out. The one closest to the engine that runs to
the side of the pump has fuel but the one towards
the outside that runs to the rear of the inj pump is
dry.
I?m baffled by this thing and would appreciate any
and all help. TIA
 
Highwayman,
Both feeds coming off the filter supply fuel to the pump. Loosen the line that enters the pump vertically at the pump rotor. If no fuel flows that line is stopped up or it is not flowing from the filter itself. If this is so start at the filter first since it is easier to loosen. If fuel flows at this point tighten it then loosen the vertical one at the pump distribution head. I just performed this procedure on my new to me 73. I find it strange if no fuel flows into the distribution head from this line.

Oh make sure the fuel cap is venting. Fuel is feed by gravity to the pump. Make sure there are no vacuum leaks all the way from the tank to the pump. I am used to Dexta feed lines which have a cam operated lift pump that pressurizes the fuel filter. The Ford Cav pump does not do this. when I loosened both feeds at the pump fuel flowed as though from the river Jordan. There may also be a screen filter in the vertical part of the rear rotary head. This I am not sure of.

There is also a bleed screw that sticks out at about 1:00 on the starboard side of the pump body adjacent to the poop deck. There should also be a return line rising up from the port side (?) and joining the return line that goes to the injector top at injector one.

That is all I know. I did not have any problems with this part.
 

You will probably also need to loosen the steel lines where they feed the injectors . Swing the battery out of the way and spin it over . When a line starts to spit tighten it up . Air bubbles will compress / expand creating an air lock which is a phenomenon that at first look doesn't seem logical . The high pressure injector pump will NOT push a line full of air through an injector .

Sometimes you can get the motor running on one cylinder and crack loose the injector line on another cylinder and bleed it .

I buy clear hose at the hardware store so I can siphon and watch before getting a mouth full of fuel . If your filters are not primed it will take a lot of cranking just to get them full . You should be able to use gravity to make the fuel flow through a filter . You may be able to use compressed air to blow backwards through the system to unclog it but be CAREFUL since too much pressure can break stuff 10 - 20 psi is enough . 100+ psi and you may be replacing a lot of parts if you have not blinded yourself with diesel spray .

When I bought my 3000 it was out of fuel . Took me hours to get it going . I thought I ran it out once an found the shut off valve has a filter that was stopped up . It still had a few gallons .I bought a new valve / filter and a manual . Now it is an easy task that I can do in under 10 minutes . While in the field and in a hurry , I bumped the starter as I was standing in front of the tire looking at the filters . Glad it did not start , now I have a working neutral safety switch .

Look at your exhaust as you are cranking it , thick white smoke means you have fuel .

I also had a hard time spinning the motor over even with every thing in natural . I blocked down the clutch pedal and it spun with ease .

You may find a picture online of the air bleed plug . The 3000's may have come with a Simms or CAV pump , I do not know about the 4000's .
 
Highwayman,

From your description your Ford 4000 appears to be one with a Cav rotary pump, but there were 4000s with inline Simms pumps.

This is probably not necessary for me to say, but listen to Ken(Ark). Some people initially do not understand that in bleeding it is necessary to start at the river source and follow it downstream. This is a sequential procedure and the last step in bleeding is to crack open each fuel line at the injector nut and wait until you get diesel fuel spraying out around the fitting. I guess you will have to clip on a remote starter switch (jury-rig) if it is not running at all. Be careful if bypassing the starter switch. If you don't know how let us know.
 

To the best of my knowledge the only 3 cylinder engine that used the inline Sims pump was on the 66-69 3000.
No Sims pump is listed for a 4000 nor have I ever seen one on a 4000.
That said: a Sims pump from a 3000 can be installed on a 4000 if one uses all of the components necessary to complete the installation, it would have to be recalibrated for more fuel flow to get hp back to proper levels

You are correct about 3 cylinder 4000 all having rotary pump. My manual had a photo caption showing a Simms inline pump, but it was from a Ford 3000. Opps. My bad. Does make me pause and thing of trying to put a Cav rotary pump on one of my dextas. A new one would be cheaper than a rebuilt Simms, but I would have to machine an adapter to fit it on to the Ferkins engine or is it a Pord?
 

We has a Dexta from 66 to 80 when my brother sold it, cheapest operating tractor I ever seen but a pain to work on.
That vacuum controlled throttle system was a piece of work that never should have been invented.
 
Destroked 450,

Besides the pneumatic governor what else on the Dexta is a PITA to work on? I would include the anvil controlled steering system because you cannot get new replacement anvils. As far as the pneumatic governor I guess I should buy a supply of chamois skins to make a few extra diaphragms as the replacements are kind of expensive. Didn't Simms use a pneumatic governor on the major, new major and super major injection pumps?

By the way. I found a P4596 to replace one of the pneumatic Simms. I know I will have to recalibrate the pump timing, but I think that is within my capabilities.

Didn't intend to get off topic so back to the Ford 4000 fuel problems.
