HIGH IDLE WHITE SMOKE...???

[lakebilly]

I believe my Super Major to be a 64
I had the bottom end rebuilt last year. It has been running like a beast all year. We had a lot of rain & when I went to use it, it revved real high, quick black smoke & then non stop white smoke. I am sure it was low on diesel, & I put fresh 5 gallons w/treatment. getting new fuel filter.

What would make it rev & smoke like that?

Do you have a hat on the inlet pipe of your air-cleaner? http://www.ebay.co.uk/itm/Fordson-Major ... SwIgNXlf6m

[lakebilly]

if you mean the cap, yes there is one, dented a bit, but it has always run well like that.

I just replaced fuel filter & was about to bleed lines when a torrential downpour started.

Billy,

To me it sounds like you should check your governor lines for leaks. If they suck air, you will get high revs and lots of smoke.

I had a line crack a while back and it did that.
Other thing can be a hole in the governor diaphragm.

Good luck!

Richard.

If he has a 1964 Super Major it will have a Minimec pump so no vacuum lines. White smoke can be over-fueled, blocked air cleaner, oil burning, low compression or head gasket.

All the information we have is, it blew black smoke then white and now has a fast tickover. It could be a faulty injection pump governor, we really need more information on what was happening at the time the problem occurred. Was the tractor working hard or was it just doing light work?

[lakebilly]

Update: Yesterday (8/16) installed 4 new injectors. Old injectors looked fouled, but not terrible for probably originals. Fired it up & no change. High idle & lots of white smoke. I called D&W Diesel where the pump was rebuilt & I was told that it was probably a governor issue, possibly a spring... due to an unusual amount of rain we've had....so now I need to figure out how to troubleshoot it.

Is there a step by step procedure to set governor?

Brian, I cleaned air cleaner/oil bath, new fuel filter, new fuel, w/Summit conditioner, & now 4 new injectors.
Could it have an issue w/fuel return lines leaking? they seemed a bit loose. I don't know if while running they tighten up from pressure ...
RH; The injector pump was rebuilt 9/16. what would cause a hole in governor diaphragm?

Leak off pipes leaking could be putting diesel into the oil which would give you smoke and high idle. If they are leaking that much you can get to a point where the engine will run just on the diesel in the oil. The engine will then run away out of control and you will be able to check your crank shaft bearings and pistons as, when that happens, they usually appear through the side of the block! (Seen that happen on a number of occasions over the years).

If your return line is leaking it needs to be sorted out without delay. You may find it is leaking from the soldered joints on the banjo connections. Check by blowing through the line and using your fingers to block the banjo connections. (Best if you are using strawberry flavoured diesel).

If it has leaked a lot you may need to change the oil again.

Otherwise, take the pump back to the people who overhauled it, there is little you can do to it without the proper equipment. I would be a little suspect of a repairer who blames rain for your problem unless he has found water in your diesel tank or in the pump. Water in an injection pump can ruin it in a couple of hours even if it has not been run.

If you try to repair it yourself, and do not set it up on the test rig, you stand the chance of blowing holes in the tops of your pistons, breaking rings and bending connecting rods. That is why, although I am trained in pump overhaul by Ford Motor Company, I will never advise anyone to attempt any form of pump repair. I do not want your scrap engine on my conscience and I do not want to involve the board in any legal problems by giving advice that, if not followed correctly, could result in engine damage.

Sorry to sound negative but injection pumps are the only part of the tractor that needs specialist repair, it is rocket science, the clearances between pumping elements and cylinders is measured in microns and the heat and sweat from your hands can have a detrimental effects on pump parts.

Banjo connections? is that where the return lines are connected to the injector? The return lines come apart quite easily. I wondered if they seal some how when the engine is running. They don't appear to be soldered, how are they sealed?

There is no smell of diesel in oil.

The Tech @ D&W was saying that a governor, tension spring could have been affected by rain?

The return line runs along the tops of the injectors under the valve cover. It is made up of four brass banjo fittings one for each injector and these are soldered on to a metal pipe which connects them all together. This pipe then goes to a brass fitting in the head which connects through the head to another banjo fitting on the outside, soldered to a metal pipe to the tank.

If the brass fittings on the injectors are not soldered to the junction pipe they will leak and diesel will get into the oil.

Sorry I do not have a picture.

There are no sealing washers, banjo fitting to injector.

Perhaps your diesel specialist can explain how water will affect any governor spring in a sealed housing. I cannot.

[lakebilly]

The lines that connect to each other, should they be soldered, or do they just friction fit together?

[Brian]

Yes, they should all be soldered together.

The pictures are a great help, firstly you have a 1962 Super by the look of it, what we call an "Orange Wheeled" Super. It does not have a Minimec pump so it is pre-July 1962.

Because it is a vacuum governed pump, it could have faulty pipes going to the governor as suggested in an earlier reply. Or it could have a hole in the pump diaphragm.

My advice is still to take the pump back to the man that overhauled it.

If your leak off pipe is not soldered together diesel will be getting in your oil without the shadow of a doubt.

Brian, I took some more pictures. I am looking through Allan Condie's book (pg 12 New Major E1As 1951-64) The pic shows a 6/63 that looks like mine. Maybe the new pics I posted will be better to determine year.

The Simms pump (SPE4A75S 647) (Bottom left corner; 439053) has less than 45 hours on it from last September. What would cause the diaphragm to split or be damaged? Is that something a novice could check?

I am trying to eliminate any other possibilities. The tractor ran great.

Here are some of the numbers off it, the serial plate near battery is all worn:

Left side under radiator. E1ADDN 5020 T3 D 3 H 5 11 69

Right side on block E1DDN 6015

Head 6050G
J3167

After June 1962 Super Majors had a Minimec Pump, "FL" cylinder head, drop restrictor on the front of the hydraulic lift and a different hydraulic lift top cover. Your tractor does not seem to have any of these. The picture of your Super is on page 11.



Minimec Pump after June 1962. Yours is the earlier pump.



Drop restrictor from June 1963.



Double acting Hydraulic lift on 1963 tractors. Different rear rocker and lift top cover.

The numbers you quote are mould part numbers not the tractors numbers but from them it looks like she has had a new block at some time or other after 1969. The number you need is one from under No.1 injector but, if the head has been replaced that number may not have been re-stamped.

All cast parts have numbers cast into them like A16B which will give month and year that part was made. After June 1963 the numbers went 3A12, year, month, date.

Billy,

If it Is a diaphragm problem, it could have been damaged putting it in. It's sometimes a tight fit, getting the circlip back in that holds it in place.
You can check it without taking it out, but either way, taking out the diaphragm is quite easy, and is separate from the "rocket science" side of the pump.
First though, check the lines to the diaphragm for leaks. Even tape the threads where lines go into the pump, etc.
I don't have my book here, but there is a simple way to test the diaphragm by removing the lines and placing the fingers over the holes, but Brian will be better at giving the right instructions on how you do it.
If you have an ITT Book for the Fordson , it'll tell you in there how to check.

Good luck!

To check governor diaphragm for air leaks, proceed as follows: Remove the governor housing to intake manifold air pipes, rotate stop lever at
rear end of pump as far to rear as possible and tightly cover the two openings in governor housing. If the governor spring returns the pump
rack to normal position, the diaphragm is leaking.
