Governor reassembled

Tonight I reassembled the governor to the 8 N tractor and it looks good. The package from YT was finally delivered. I put a dab of grease on bolts and the housing itself then put the internals back into the cover and bolted the cover to the tractor torquing to 7 foot pounds. Literally 112 inch pounds as I have an inch pound torque wrench. I need an extension to go from ¼ inch female to something larger male. I could not get to the top bolt with the wrench so simply guessed based on how stiff the bottom bolt felt which was indeed set to 7 fp.

Next comes the rear light wiring harness, for which I have some pictures as well as descriptive text. Then the brake job which requires me to raise the rear and remove those big wheels. I must check to determine whether the 6 ton jacks will extend high enough else get some wood to build a couple platforms. I am smart enough to avoid sintered block called cinder block as it can shatter at inconvenient times due to the weight on it.

Cub wiring

The wiring harness of the ’49 Cub is now replaced along with two other wires. One of them went from the GEN terminal of the Cutout Relay to the A terminal of the generator, while the other went from the distributor to one side of the coil. The first was too thin, about 20 gauge so I replaced it with ten gauge wire. The second was old and also seemed thin so I replaced it too with a bit thicker wire. When I put on the ends to the wire, I do what I learned from my father which is to solder the connection in addition to crimping it. The wiring diagram in the owner’s manual did not match what was actually on my tractor. It seems the old Cub has a Cutout Relay instead of a Voltage Regulator and all my standard sources displayed the VR. Once again the Farmall Cub Gurus of www.yesterdaystractor.com helped tremendously. The best help was to a site set up by Farmall Bob which had diagrams of the electrical system of old Farmalls. One was exactly what I had in front of m...

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...
