Re: 1950 Farmall Cub Refresh
I wasn't able to get much time in the shop this weekend. But got enough to where I could get the hydraulic system reinstalled.
With everything painted, the original leather boots cleaned and new o-ring for the control valve, we are ready to go.
First up was installing the new o-ring on the control valve and installing the control valve with the leather boot. I also installed the leather boot on the piston rod. Boots look pretty good for using the parts washer and then some dish soap for cleaning.
Once I got the arms back on and everything connected again, I put the block back on the tractor.
With the pump rebuilt, painted and reinstalled,
I reinstalled the tubes and the control linkage to the lever.
I just need to add some hytran and the Hydraulic System is done.
Next up on the TO-DO list, fabricate a new bracket for the alternator. The bracket that came with it, had the alternator hitting the hood. At least they didn't cut the hood for clearance.

Re: 1950 Farmall Cub Refresh
After you fill the TC Block, leave the fill plug open. Since your piston is extended at this time, start the engine and operate the TC Lever several times to expell any air in the system. Then set the piston fully retracted and shut the engine down. NOW top off the block, if needed.

Re: 1950 Farmall Cub Refresh
This weekend I was able to fabricate a mounting bracket for the alternator. When I bought the tractor it was already converted to 12v. However the bracket that was installed holding the alternator allowed the alternator to hit the hood. Fortunately, they did not cut the hood. A few weeks ago I bought the NAPA 213-4011 SW alternator.
To get started, I needed to know where the edge of the hood is going to be. So I found a scrap piece of wood that conservatively represented the gap between hood hanger and the side of the hood.
With this, I used some welding magnets to hold the spacer on the radiator shields.
With a little trail fitting and a lot of double measuring, I ended up with this mounting bracket. I had to make the Aft end of the bracket a little thicker so the front end would clear the governor.
Due to the mounting bolts, I had to place one of the alternator lugs between the bolts. I will find some sort of spacer to fill the gap.
With the alternator mount installed, time for the tightening bracket. This was a little easier to figure out. I was able to cut the original bracket in two, then add a little extra material and put the two pieces at an angle relative to each other.
I will need to add a spacer on this bracket as well.
Once everything was done and bolted into place, I had the alternator mounted, using the belt that came with the tractor, NAPA 4L210 and having plenty of clearance to the hood.

Re: 1950 Farmall Cub Refresh
With the alternator bracket out of the way. It was time for the second tractor split. This time we will be taking the front axle and bolster off. This will allow better access to cleaning and painting the front of the engine.
We started off by taking the tie rods off and then dropping the axle.
Once the axle was off we removed the steering housing. This revealed the lovely grease that was used as the lubricant. I was not surprised to find this as there was a grease fitting installed on the fill port. The daughters will have fun cleaning this up.
Now it was time for the bolster to come off.
Now we have plenty of access to the front of the engine.
When the outside temp gets above freezing again, we plan on flushing the engine's water jacket.
Before closing shop for the night, we thought we would chase some threads. Only one problem, there is not enough room to get a tap in the Air Cleaner mount holes with the engine's front coverplate installed. To solve this problem, I taught my daughter how to make a thread chaser by cutting a slot in the end of a bolt. Worked like a charm and the threads are now clean.
We now have a pretty decent pile of parts that need cleaning, priming and painting. As far as I know, the only repairs that need to be made is removing 3 broken screws from the bolster that holds the dogleg panels and reworking/installing the radiator overflow tube. The steering housing will also receive all new gaskets and seals when we go back together.
With the tractor being split for the second time, it feels like we are over the hump and can see the end.

Re: 1950 Farmall Cub Refresh
I have been following this thread since the beginning, but haven't gone back to review all the things you have already done. So if you already covered this, just ignore...
While you have the front off, you have access to the hard-to-access governor lever, so now is the time to ensure the spring is good (replace NOW if not), the lever moves freely, and there is no slop in the gov rockshaft or the linkage across to the carb rod. Oil the fan, too!
Being female myself, I just LOVE seeing your daughter's participating! Even if they never work on a project like this again in the future, the knowledge and self confidence acquired will always stay with them!
My congratulations to them!! (and you, too!)

Re: 1950 Farmall Cub Refresh
Your alternator bracket looks very familiar, I’ve made several similar ones in the past. You might, slightly, increase the bends in your upper bracket, to eliminate the need for a spacer, there.

Re: 1950 Farmall Cub Refresh
Looks like it has been a while since we were able to work on the cub. In January, I had an ER visit for a blood pressure spike, then it got a little to cold, then spring and summer came. But we are now finally back at it.
Over the spring, I was able to flush out the engine
My oldest daughter and I were able to attend the Barnyard Bash. This year we brought a few projects to work on. One of them was drilling and retapping the holes in the bolster for the doglegs. We also made a new overflow tube. The tube that I got from TM did not fit correctly. We had an interference with the upper radiator pipe. We used a piece of copper tubing, bent it into shape and then soldered it into place.
Now that the holidays are here, I have two weeks off of work and plan to make up for some lost time. We finished cleaning the engine, air cleaner, fan and distributor.
When I took the distributor off, there was no oil found between the housing and engine. Looks like the seal is still good. But I did notice that one of the distributor clamps is missing. A quick call to JP Tractor Salvage is going to fix this problem. The part will be put in the mail tomorrow.
Next up will be cleaning the Bolster and getting that into primer and paint.

Re: 1950 Farmall Cub Refresh
Next up was the front axle
During the clean-up found a surprise. There was a crack near the center pivot
To repair, I first cut a V-groove
Then ran a bead of weld and polished it smooth

Re: 1950 Farmall Cub Refresh
A little primer and some paint, and the axle doesn't look too bad.
We also got the Upper and Lower coolant pipes cleaned up.
Other than getting the front rims cleaned up, I should be able to meet the goal of having the cub back on all fours again by the end of the year. The pile of parts that need to be cleaned is starting to get rather small. I want to try and have everything ready for final paint by the end of January. Then I will set it aside until July when it gets hot and put on the final paint.

Re: 1950 Farmall Cub Refresh
I had a friend come over and help out in the shop. With all of the parts we were able to clean, prime and paint the last two weeks, it was time for some reassembly.
First of was reinstalling the distributor.
I am using the old Cap as masking. Once we final paint the tractor, I will put on a new shiny black cap.
Next up was the Air Cleaner and the fan.
I don't like the idea of paint on the belts. I will need to figure out a way to mask them off. I needed to install them now since the alternator belt is too small to thread around the fan later.
Finally time for the big pieces. The Bolster, Steering Assembly with new seals and the front axle went back on.
I also plan on masking the cooling hoses prior to final paint. I wanted to install the water pipes now so I could repair the paint damage on the bolts during final painting.
I made our goal of having the tractor back on all fours even thought the front wheels are not done yet.
Next up are the front wheels and tie rods.

Re: 1950 Farmall Cub Refresh
Before I had to go back to work last week, I was able to get the Steering Rod, Starter and Tie Rods cleaned up. Over the weekend, I got the Steering Rod and Starter installed.
I couldn't install the Tie Rods yet. When I took the Tie Rods off last year, instead of finding the Tie Rod Ball Seats, I found small nuts being used. I am waiting on new ball seats from TM Tractor.
I also had a little time to take the Tail Light apart and determine what parts I need.
I have an order into Brillman for a new switch, terminal plug and lense clamp ring
The headlights that came with the tractor are brand new and work perfectly with 12v bulbs already installed.
This coming weekend is a long weekend with Monday being a holiday. I hope to get a lot closer of having this project ready for paint.
