Old Diesel Ford Tractor

[Dbonzi]

My dad has an old Ford major deisel tractor, anyway it didn't run very well, no power. We cleaned all the gunk out of the sediment bowl, and fuel filter. Well put put it all back together and now it won't run at all. It has a Simms injection pump on it, the kind where it doesn't have a throttle linkage to the pump. It does have what looks like a butterfly valve in the air intake with two pipes running to it from the injecton pump. Anyways can anyone tell me what might be wrong here. It won't fire at all now. The pump is getting fuel and there is no air in the lines and we bled the injection lines aftter the filter clean up. Haven't had much expirience with this kind of a pump.



Thanks

If you're getting fuel all the way to the injectors about the only thing that could be wrong is the battery is down to much and not cranking it fast enough.

Those are one of the first direct injected diesel tractors made. Boy do they knock. Love that sound at idle. The pump linkage is funny and I forget the details but that would be the first thing. Also, they use a compression release ( lever on the valve cover) to start. Their starter is geared to spin the engine very fast with decompression the you hit the lever while its spinnning fast and it comes to life or slows down and you start over. Make sure the compression release is working correctly. I used my friends major diesel on and off for almost 20 years and it ran great with little maintanance. The Simms pump is pretty simple and reliable, just be sure to never hose it down hot on the pump when it's running. It has an aluminum body that can crack or cause a plunger inside to seize. Recheck your fuel supply, compression release, and linkage.

We have one of these too, a 62' (I believe) Ford 901 Diesel and as far as I know has never had the head off of it, it's in dire need of freshening!

Thanks for the replies!

I also for got to mention it will run on strait either sprayed in the air cleaner and still will not run on diesel?

Dennis;

Whoa on the ether. Way too dry. Use WD-40 instead of ether to assist any engine in starting



I'm thinking the compression is way down and causing the power lose. Trying to remember the Simms pump. Some must be bled while cranking the engine or it will still hold an air lock. This might be one of them.



John Deere model "R" was the first practical open head (direct injected) diesel engined device. It predated the Fordsons by 5 or 6 years.



BTW, I have 3 GSKs lined up for this summer. You have yours yet?

JohnE:

No on the GSK's

Was thinking about it pretty seriously. But I got laid off last week so now have to watch the pennies pretty close.

Hopefully I will come up with something soon. That way I can get back to driving around in the old diesel just for fun!!

Thanks for the advise on the tractor, I'll get back to it sometime this week.

Take care

Dennis----It sounds like you have a pump that is controled by vacuum from the butterfly venturi assembly. I remember working on one about 30 yrs ago. The Simms pump is not engine lubed ,

and has its own oil in the cam box. You should have two (2) small plugs on the side,one near the bottom and the other about 1 1/2 inches above it. remove the plugs and drain the oil,if there is any left. The oil should be changed every 200 hrs, but most farmers never knew that. With out the oil the camshaft,roller tappets ,

springs etc. will be rusted and the pumping plungers will be stuck.

There is a side access cover on the side held on by two (2) screws

Remove it and crank the engine to see if the cam mechanism is operating the plungers. There is a plug bleeder screw on the high press. block where the lines connect to the pump . Bleed the air out of the fuel at the plug,then while cranking crack the lines loose at the injectors to bleed the air. GOOD LUCK. Email if you have questions. Oh forgot, fill with engine oil to the top plug.

Thanks again
