Anyone who can help, I appreciate it. I just recently aquired a 1955 Fordson Major Diesel Tractor. Very Very good condition. My uncle had it for a long time. The starter went out on it aobut 8 years ago and it has sat ever since. I have put a new starter on it(had fun finding that!), cleaned out the gas tank, new muffler, new breather. New fuel line. Problem is, I am not getting any gas to pump. There is the little glass "thing" with the pump on the bottom. I have gas to there. From there it goes up to a metal cylinder with a filter in it. This thing is filling up with gas and it is not going anywhere from there. I dont think. Am I doing anything wrong? I tried pushing in the cold weather button on the back of the Simms pump, but didnt help. I really would appreciate any help. I got the tractor for 500 and couldnt pass it up My uncle assured me it worked fine when he parked it.

Other questions....
Does this have glow plugs? Before I found this forum, I tried starting it with starter fluid. It started right up. Sounded great!!! Then I saw this forum and noticed alot of people saying to "not used starter fluid". Hope I didnt tear anything up. Is this a Perkins engine?
What is the lever on the front of the engine, at about valve cover level for? I have to push it all the way down for the engine to turn over. Anyhow, thanks again in advance for any future help. The forum has already been a huge help.

My email address is rscj@intellex.com if any of you want to email me an answer.

I have tried and tried, and it will not start. I bled the fuel line all the way to the pump. From there I took of each injector and turned over the engine and it seems like the fuel is flowing, but I am not sure. The black thing on the dash that you pull to kill the engine has a bad cable and the thing that it pulls is all the way back. Shouldnt it be forward? It feels like it is trying to start. It reminds me of an engine that isnt getting fire. How does a diesel engine ignite the fuel if it doesnt have spark plugs? Anymore help? Just out of curiosity, if I needed one, how much would a new Simms pump cost? Thanks in advance.

The "thing that kills the engine" (the small lever above the injector pump) should be facing the front of the tractor when running. When you pull the black knob on the dash the lever goes back and the engine stops.

The diesel engine has much more compression in the cylinders (Fordson Major has the comp. ratio 15:1) than a gas engine. When the air in the cylinder is compressed that much, it becomes hot. When the piston is near it's upper point, the diesel fuel is injected into the cylinder (by the injector pump) and the hot air ignites the fuel. In Fordson major there is a lever on the front of the engine. It is called the decompressor. When the lever is up, there is a lower compression in the cylinders making the engine easier to turn by hand crank. It is not meant for starting however. When the lever is down, there is the normal compression in the engine.

I've heard that the Simms pump would cost very much.

Have you checked the timing of the pump? If it's not correct it could cause the engine not to start. The correct timing for a 1955 FMD is 26 degrees before the upper point of the piston (sorry, I don't know the right term for that, maybe it was "26 deg. BTC" or something).

I hope you mean Diesel and not Gasolene. If you put gas/ petrol in the tank, dont atempt to start, the engine will self distruct.

Anyway, there are two 1/2 in screws on the top of the fuel filter (that metal cylinder), slacken the rear one of and work the lever on the lift pump untill diesel flows with no air bubble. Tighten up (dont over tight, they strip easy). Repeat with the second screw at the front of the filter. There is another similar screw on the injector pump just below the injector pipes. Bleed that one. The tractor should now start but you need to allow time for the pump to get the diesel up to the injectors

The other questions fist

>glow plugs?
nope

>starter fluid
Dont EVER use it!!

>Hope I didnt tear anything up. did you just gave it a short wiff?
or did you spray for more than one second?

>Is this a Perkins engine?
Nope its a real Fordson diesel

>What is the lever on the front of the engine, >at about valve cover level for? Valve lift lever, Not to be used with starter,
only hand cranking.

Did you bleed the system all the way to the
simms pump and the injector lines? I would check
that fist. Bleeding might take a while though.
Check and see if the timing is ok maybe the little disk from the pump drive is broken

Hope this helps

Regards

if stop lever was fully back for a number of years maybe the rack inside the pump is stuck take cover off pump and see if it moves when pulling stop lever back
