First I hope that I am posting on the right forum.
I have a 1957 Fordson Major, serial # 1426564
I ordered a after market replacement coupling off the Internet and had to get some machine work done so that it would fit.
Finally got it back and put it on today and now one of the injectors does not seem to be working.
I took detailed photos and video, hoping that someone here can tell me whats going on.
When I pulled the side cover off my Simms Injector Pump I noticed a round ring suck under on of the pieces inside.
I pulled this ring out and it hit me in the nose and cut a gash in my nose. OUCH!
Then as you will see in the photos and video, one of the infectors is not working.
What should I do now? I have over 200.00 in this coupling and getting it machined to fit.
I'd really like to get this pump rebuilt but am open to ideas....
Would a pump off a super major work? What are my options at this point?
The photos I took are located at:

Thanks for any suggestions or information.

My 57 Major Simms Injector problems
Re: My 57 Major Simms Injector problems
Larry,
What you describe as a 'ring' being in the pump, is more than likely one segment of the spring. In other words you need a new spring. Your pump is very dirty and appears it may have had water through it at some stage.

Re: My 57 Major Simms Injector problems
The video clips show that the left hand spring is not being compressed, if that is the position from which you removed the "ring" then in all probability the spring is broken and the plunger is not in contact with the cam. As a consequence there will be no fuel delivered to the injector.
Refurbishing your pump is not a DIY option, your best solution is to remove the pump and take it to a specialist who can strip, rebuild and recalibrate the pump.

Re: My 57 Major Simms Injector problems
Larry,
I think you have a few options.
First a question. Do you have the engine with the throttle through the engine or in front. Because you have a setup with air lines from the outlet manifold to the pump above the temperature thermostat with different sized pipes.
I use to have that to, but those were the wrong size and the engine was idling to high. Now I have the equal size lines going under the temperature thermostat. These are from a older engine. But my idling speed is now to low.
Option one: You can by a new pump and exchange the old one. This is often cheaper than refurbishing a pump at a specialist.
Option two: Refurbishing it at a specialist.
Option three: Look for a second hand pump. Be sure that this pump is stored well or comes off a engine that has recently run.
I bought one from a running engine they say, but it was a long time ago the engine had not run for a long time and a lot of water came into the pump.
Option four: Refurbishing the pump by yourself and find another spring. I have done two. The main thing is to work very clean. Keep all parts together at the same cylinder number, store clean parts in clean diesel. Leave the rod with the four control forks in place. Do not turn on the cold start calibration and the damping valve at the front of the pump. You have to remove the camshaft to see if it's ok and clean it.You have to replace the two oilsealings.
If you want to see how I have done it look at http://people.zeelandnet.nl/hmdetroije click on repair and then repair 5.

Re: My 57 Major Simms Injector problems
You can see where the spring is broken on no. 4 plunger, in your first picture. The piece moved from there to where you found it. The spring on no. 1 doesn't look very good, either. You can see where two of the coils are touching each other.
It also looks like the the set-screws, that hold the forks on the control rod, have been turned with the wrong wrench at some point. That probably was not done by a fuel injection shop, so you should take it to a shop to make sure its calibrated correctly.
A pump off of a Super will work if its the vacuum governed one, like yours. A later Minimec pump won't fit because of different mounting holes in the block.
