A while back I was stuck in the mud with my Farmall Cub tractor. I was furiously running the throttle up and down, back and forth trying to get enough momentum to break free and get the tractor moving forward instead of downward into the mud. I eventually drove out (with the help of some come-alongs), but I had bent the throttle rod slightly. I thought that I could bend it back, but when I tried the throttle adjusting lever that connects the rod to the governor broke off. Ooops!
The solution at the time was a washer and some cold welding compound. I used J-B Weld, which seems to always do the trick. The first two photos show the piece with the welded washer.
This worked for a while, but I knew that I had to get in there and put a new piece in before the snow starts to fall and before it gets too cold to want to mess around with small parts under the hood of an antique tractor.
The unfortunate thing was...I had to remove the hood/gas tank to get the old part off. After unhooking the lights and a few bolts, off came the hood.
While I was in there I was able to tighten up a squeaking belt by adjusting the alternator, so I was able to get two tasks done at once.
I wanted to replace the belt on the alternator, but that required removing the fan, the main drive belt, and a bunch of other things that were in the way. Simply tightening the belt, however, worked out in the long run.
Once I had the hood off, I thought that I could easily slip off the broken piece on the throttle lever/governor unit. No so. I had to take off the entire governor. I was a bit nervous, but it went right back together. I snapped several photos to be sure to have evidence of where everything went in case I got lost on the re-assembly.
I wish I had the luxury of having the hood off when I was wiring the tractor up for lights, switches, and the amp meter...everything is so easy to get to! I remember bashing my knuckles trying to remove the manifold with the hood on. It would have been alot easier with the tractor like this!
Here is a close-up of the welded piece. It served its purpose, but I didn't think it would last the winter with the workout that plowing snow puts on the tractor.
Below is the new piece all attached and ready to receive the throttle rod. They don't manufacture this piece anymore, but I was able to find a used one, all sand-blasted and painted, from a used tractor parts dealer in Texas.
The next shot shows the extent of my dismantling...I had to remove lots of parts--parts that were not even near the area that I was working on. Amazing engineering on these little tractors.
Here is the governor just about to be pushed back together. It was a perfect fit, lucky for me.
While the throttle rod was unattached, I was able to straighten it out. Now that everything is back together, the throttle travels the full range perfectly. Also, no more alternator belt squeal!
Bring on the snow!
