8N Starter and Solenoid

Today I tried an experiment. I removed the cable from the starter. It goes to the starter solenoid. Then I ran a 12 volt battery cable from the positive post of the battery and touched that post on the starter. The starter turned over just like it is supposed to. So now I know the starter is good. I took an ohm meter and checked the starter switch, starter button, and small wires from the solenoid to the ammeter. All were sound. The starter button made a connection when I pressed it down which is just what it is supposed to do. So I now know for certain the problem is the starter solenoid itself.

What I do not know for sure is whether a six volt solenoid will work with a 12 volt system? That is the question. I will go out to the net and see if there is a 12 volt starter solenoid with three posts. If there is not, then I will replace the dead solenoid with the six volt new one that is in the box in picture 413. Picture 412 is the solenoid. Picture 411 is the starter showing the post I put full 12 volt positive connection to.

Farmall Cub Switch Replacement

It was a cold, wet, dreary day in Central Texas. Perfect weather in which to replace the light switch I replaced last week. The first replacement was blowing a 20-amp fuse in less than a second when turned to the farthest right position. Fortunately, I had added a separate fuse holder to the circuitry when the replacement did not have a fuse position. I spoke with the nice folk at Farmall Cub Forever and ordered a three position six-volt switch which arrived a few days ago. This time I took pictures so you can see what I was doing. Again, I replaced one wire at a time. The switch has a protrusion which fits in a notch in the console, and I replaced it so the two were properly aligned. I discovered it was easier to take the console off this time, and I did not need a small monkey to reach in the confined space. I did; however, forget that I placed a piece of board between the hydraulic housing and the hood/fuel tank. So, when I started up the Cub to see how well it would run, there...

Farmall Cub greasing

Replacing gear oil and greasing the ’49 Cub ought to be a straight forward task(s). Well it hasn’t been. The transmission fluid was tan, looking like tan paint. Folks on Yesterday’s Tractor Farmall forum said it meant water had got inside the transmission. I wonder whether this tractor was under water at one time. I bought a Spectricide brand insecticide pump, put kerosene in it, and flushed the transmission, then refilled with 90 weight gear oil. The gear oil looked like and had the consistency of thin honey. Pic 1300 shows the transmission filler plug. A lot easier to reach than the plug for emptying the transmission. Note it has a square head. All of these plugs are square headed. Three and a half pints later, the transmission was back together. After the transmission, I decided to check the steering gear oil. It was not tan. It was black as could be so I flushed the housing with kerosene again and refilled with ¾ pint of 90 weight gear oil and replaced the filler plug. Pic 1301 s...

Cub gas tank and hydraulic pump

Sunday I was going to put the fuel filter and shut off device onto the gas tank of the ’49 Farmall Cub. On the bottom of the gas tank which is an integral part of the hood, there is a brass hexagonal adaptor threaded on the inside. The fuel filter does not fit on this hexagonal adaptor. The shape is different and the size is different. I will ask help from some knowledgeable people to solve this. As soon as I have this solved, the hydraulic lift can go in place. The fuel tank on the hood becomes THE fuel tank for the tractor. The hydraulic pump goes on the left side of the Cub engine near the bottom. A cover plate is removed so the pump vanes can be put in their place. Two bolts of 5/16X28 and 1 .75 inches long are needed to hold the pump together. Two longer bolts hold the pump to the tractor. I need to buy the shorter one or cut a longer one off myself to fit. Tractor Boy.
