2N Solenoid???

[Nmccumber]

Hoping someone can help me out.

What is the large cylinder on the front of the steering box? I assumed it was the original solenoid being it has terminals and old wiring. Everything I see online says the part below it is the solenoid but Im pretty sure thats what is connescted to the push button start.

Online world also says the 2n didnt have a solenoid... ?:?

Thanks,
Nick

That is the original starter switch activated by the push button located by the shifter. The other piece hanging in front of it is a solenoid that has been added probly when original switch failed. You are correct the N's didn't come with a solenoid from the factory. I just replaced a starter switch on a 2N last fall, they are still available and prevent the tractor from starting in gear.

It looks like someone "jury-rigged" a VERY dangerous Ford solenoid to start the tractor. Get that outta there! Next, you need to buy the IT shop manual and you'll see how easy and affordable it is to fix things right.

Hi Nick, the "large cylinder" is a 9N 10505-B generator cut-out.
Voltage regulators didnt show up till 8n.
Edit:
I'd forgot about the early 9ns having voltage regulators--- my bad. Thanks MF

Thanks for the replys! So if I want to keep this original as possible (this will be a shed tractor) what do I replace it with?

 

[HarryVanderpool]

New wires.

The original starter switch is the part at the bottom of the housing with the two large electrical terminals. One terminal should go to the starter, the other from the battery. The switch is operated mechanically by the button in front of the shifter. The two are an IMPORTANT safety feature as the mechanical starter button only operates if the gear shifter is in neutral.

Battery terminal will depend if the tractor is: 1) still original 6V+ ground w/generator---> - battery terminal, 2) 6V- ground w/generator (generators can be run + or - ground, have to polarized correctly)----> + battery terminal, 3) or is it converted to a 12V system w/alternator? in that case it would be a - ground and switch connected to + battery terminal. See pictogram.

The other round can is as mentioned a voltage cutout for a 6V 3-brush generator. The 3-brush generators did not utilize a voltage regulator and output is adjusted by moving the 3rd brush physically by a screw on the generator. 1 wire comes from the generator, the other goes to feed the battery at the junction/resistor block that also holds the resistor to the coil.

We would need to know if the tractor still has a generator, and if so is it a 3-brush/1-wire (bottom pictogram in attachment). The other type of generator /2brush has two wires and uses a voltage regulator which doubles as a cutout and output is regulated by the regulator (top pictogram).

Pictogram by member JMOR. He blessed us with lots of wiring diagrams for various setups

Alternators are wired differently depending on what type.

Post a picture of your generator or alternator to figure out what you have/need.

I hope my explanation was not (too) confusing

The cutout is sold on this (YT) site. You need to paint it gray to look original. They also have the starter switch, but not the push button or rod.

I have read here that the starter switch assembly wears down to the point where it won't work. The fix is to drop a coin in it. Apparently the coin goes between the back end of the rod 9N11512 and the lever 2N11515 that pushes it. I have yet to see a post that actually says where to put the coin, but that seems to be the only place for it. The parts are illustrated on the bottom of page 123 in the FO-4 manual. The link in the post for a push rod from Steiner is a valve train part.

You do have the 1 wire generator? Some 9N and 2N tractors were refitted with a 3 wire 8N generator that used a voltage regulator, and not the cutout.

The coin goes on the starter switch.

The coin goes on the starter switch.

My point exactly.

In the picture below, the starter switch is circled in red. The coin is the yellow thing that is on the starter switch. I have not tried it, but I am quite confident that while it is exactly as described, it is not as intended and will not work. It would fall off as soon as the engine started, but since the engine will not start, it may stay there. The push button is circled in blue and the yellow coin is between the lever and rod. If you can jamb it in there, it will stay put, but whether it will work, I don't know.

I worked for a place that makes satellites for a few years. Our technicians were the world's greatest experts at misunderstanding written instructions. The term deliberately obtuse comes to mind. Perhaps this ability to misunderstand instructions has rubbed off on me. Judging from the thumbs up, Mad Farmer understood what you meant. Before I worked there, I might have understood it too.

My understanding has always been the coin goes on the starter switch as follows

1. Remove starter switch
2. Affix coin to end of pushbutton using an appropriate adhesive
3. Reinstall switch

I think I'd use a REAL COPPER penny so if the coin comes loose and makes it's way into transmission........
