Need Help With Inector Pump

Bryce Frazier · Oct 30, 2016

Had my Ford 4400 4 cyl injector pump rebuilt, and I have it pretty much all the way installed, and I went to hook up the 3 high pressure lines, and ran into a wall. At the back of the pump, where there 3 lines hook on, the piece is twisted, counter clockwise, about 1/3rd of a turn. So, from looking at the back of the pump, instead of having a port at like 11, 1, and 3 O clock, they are like 9, 11, 1. Can I turn that piece some how, or do I have to take this @@@@ thing off and send it back down to them?? Thanks!

If a pump repair shop actually mucked it up, for gosh's sakes have THEM correct it.

In a case like this a "before" photo would be nice to have!

While I agree with Bob's advice, I am more confused than you. My only familiarity with Ford is my 655A backhoe. It has a 4 cyl. engine, I believe common with tractors. It uses an in line pump. I think the three cyl. 555 uses a rotary pump.

I looked up Ford 4400 on tractordata, and don't find it? The 4000 shows it's a 4 cyl. You say 4 cyl., but three high pressure lines? On any rotary pump I have worked on the openings around the head are evenly spaced. Your clock references are anything but. So what's really going on?

???? got me wondering too---I have seen some pumps with outlet port connectors & plugged ports, but that is pretty much 3 or 6 cyl I think???

On the three cylinder Ford CAV DPA pumps, looking at the back, all fittings are aimed to the right. Outer fitting at 3 is pointing up, the outlet at about 7 should point down, right. Outlet at about 11 points up, right.

I'm confused, why did you have a 4 cylinder pump rebuilt for a 3 cylinder tractor?

Bryce Frazier · Oct 30, 2016

Ya, I screwed that up didn't I!

It IS a three cyl, diesel tractor. Ford 4400, about a 1973 I think. It is the Utility version of the 4000, but has the same engine as far as I can tell.

There are three heads available for the Dpa 3 cyl. One has six drilled and tapped ports. Three are plugged. Second is the Roto Diesel version used on small John Deere German built tractors. These heads are hard to come by and priced like wise. The ports are turned 30 degrees from the Ford version. The last is of coarse the Ford style. I learned this the hard way by buying a ford 3 cyl. pump core and putting the head in a John Deere Roto Diesel pump. I built it, tested it, and shipped it off. Then I got a call from the owner saying he couldnt get the lines to fit. So I then had to find the correct head and build him another pump. So now I am smarter, and have Two Ford 3 Cyl. pumps here rebuilt and ready to go if some one needs one,,,, or Two!! Check n see. You may have the JD style head in your housing . They both are clock wise and work the same except port location. Good luck,, Al
