Sunday is Cub Day

Last Sunday afternoon, just before going off on my last TDY trip as an Army officer, I decided to adjust the carburetor on the ’49 Cub. The manual states it to be a simple job. Just turn the adjustment to one revolution, run the engine until it is warmed up, retract the throttle and then turn the adjustment either in or out until the Cub engine runs smoothly. Advance and retract the throttle to check the adjustment. Simple; however, the engine died and was difficult to start. Once again I had forgotten to pull on the ignition switch. Finally, after fiddling with the adjustment a while and getting the engine to stay running, I drove the tractor into my Tractor building and shut it down. I was quite concerned that I was going to have to push the Cub into its parking place which is difficult to do. Usually I use the 8N Ford to push the Cub into the building. Fortunately I did not have to.

 

Today, a week later, I had charged the battery, tightened the negative cable on the battery, and was ready to try again. Instead of pushing the tractor out of the building, I decided to start it in the building with the sliding door open. I pulled the ignition switch, pulled the choke to full on, and pulled the starter ring. The Cub started up in about four seconds. Putting the choke at half choke (the carburetor is designed for this) helped the engine to run as it warmed up. Then I pushed the choke off and listened to the engine run quietly under no load. No smoke from the exhaust and no roughness in the sound. I shut it down, happy as can be. We are approaching the end of the refurbishing. In the near future I will push the tractor into the yard, run the engine until it is warmed up, and again adjust the carburetor. Once it is okay, then the Cub will go to the radiator repair man for soldering the overflow tube into its place. Once that is done, he can flush the radiator. Only then will the hydraulics be put on, filled with hydraulic fluid, and tested. The fuel filter will go on the tank and the hood will be put back on the Cub. Finally, decals will be put on and the front lights will be tested. I may have to use the ground wires on the electrical cable if the lights are not adequately grounded though the hood and frame (hood supports?). I am about ready to find some implements!

Farmall Cub Switch Replacement

By Robert Adams
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

By Robert Adams
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...

Uncle Phil Cause of Death

By Robert Adams
Phil was hit and killed by a drunk who was driving on the wrong side of the road and then left the scene of the collision. The man then hid in the nearby woods. Authorities found him, took him to a hospital, then he was arrested and jailed (in Vanderburg county) and is awaiting extradition to Wabash County. I hope he stays in jail until convicted. Uncle Phil was totally innocent, minding his own business. I have known Phil since he was fifteen years old. That is a long time, sort of.
