You all are doing a good job! Keep it up! Good to see your girls involved and echo Dale's sentiments earlier about getting them involved.

We have made a little more progress over the past week or two. We have finished cleaning and priming all the parts for the final drive, and even a little paint in the hard to get to areas after assembly.

The wheel center has made a trip through the blaster and has been since painted.

The newly repaired brake band has been painted along with the bolts to mount the wheel weights. I also made and painted a bracket that will mount using the starter bolt holes and a side wind jack for splitting the tractor. We need to replace the rear main seal and assess the clutch. A few months ago I took the round clutch cover off to discover that two of the adjusting bolts have fallen out of the clutch.

To round out the weekend, my youngest came out to the shop wanting to help. So, I taught her about a new tool and her chase the threads in anticipation for installing the final drive.

I think we have us in pretty good shape to make some good progress over Thanksgiving break putting the Final Drive back together.

I could not say tractor when I was 2 years old so I called it Err Err.

I loved this tractor then and I still love it now.

Over Thanksgiving break, we were able to check off a few more boxes on the to-do list. I am going to split the update into several posts so I can share more pictures. I always enjoy looking at pictures of others work.

We started off by cleaning the rest of the transmission and steering column and getting them into primer and paint.

Then we reassembled the Final Drive and finished priming and painting that as well.

While we waited for the paint to dry, we did a trail fitting of the Splitting Stand Bracket we made. We are using the starter pad to attach the bracket.

We also bolted a caster to the bottom of a side wind jack to roll back the rear end. I have the jack temporarily installed on the engine side just to see how everything fits and to verify that the handle did not have any interferences. When we go to split the tractor, I think I will leave the engine stationary and roll the rear end away.

With the Final Drive and Transmission ready for reassembly, we are still one part shy of being ready. We still need to install the new brake lining. With some help from my oldest and the instructions found in the how-to section (http://www.farmallcub.com/phpBB2/viewto ... 54&t=66324), we are off to install the lining.

First we preformed the lining so it would fit into the brake band. Then I used another brake drum and some zip ties to help finish forming the lining. After we had the lining formed around the drum we slide the drum half way off and clamped the lining to the band. I don't have many small c-clamps, so we used some anchors that are used for securing a tarp.

Once the donor drum was removed, we marked the holes on the lining. First using a small diameter drill bit for the thru hole, we then used a drill bit from my pocket screw kit. You just need to be careful when drilling the counterbore that you don't get too deep.

With the holes drilled, now it is time to install the rivets. For a bucking bar, I ground the tip off of a large nail spike and secured it in a vise so the head of the spike was resting on the vise arm.

With the help of a few extra hands, we set the rivets. What worked for me was first using a Center Punch to start the flare, then a Roll Pin Punch to continue the flare, then using a Flat Punch to finish peening everything flat.

Here is the end result. We are now ready to install the Final Drive.

Actually, this whole thread should probably be moved to the Farmall Cub Forum. There’s much more here than just photos.

With the paint dry and the brake relined, we set off to install the Final Drive. I know what you are thinking, what about the Fender, that needs to be installed with the Final Drive since they share the same bolts. It was my desire to install the Fender at this time, but the Fender needs a little more attention than I was planning. I didn't want to hold up other parts of the project so only installing the two bottom bolts and one on the top, we reinstalled the Final Drive. When the Fender is ready for installation, I just need to remove one bolt and we can install the fender along with the four remaining bolts.

With the Final Drive on we reinstalled the rear wheel with the Wheel Weight installed as well.

It is a rather nice feeling to be done with the Final Drives. It seems as if we have been working on them forever. Considering we dug into the Right one in January of this year, forever may not be that far off. Either way, time for something new.

Next up, we removed the Dash Panel, the Hydraulic Tubes and the Hydraulic Block.

I recently tested the hydraulic block and everything seemed to work as it should. Now that I have it off of the tractor, is there anything I should inspect?

With the Hydraulic Tubes off, we are all set to split the tractor. We need to split to replace the Rear Main Seal and assess the condition of the clutch. When I first removed the clutch cover a few months ago, I found two of the spring finger bolts at the bottom of the housing.

TST, if you are reading this, I will be contacting you to have the Seal Housing reworked for a new seal in a couple of weeks.

One final thing we did to close out the weekend was to install plugs in the spark plug holes. It turns out that Oil Drain Pan plugs have the same M18-1.50 threads as the spark plugs. I wanted to get the spark plugs out of the way to make cleaning and painting the head easier.

We probably won't get much done next weekend as that is my Wife's favorite holiday, Tree Getting Day! We make a day of getting the Christmas Tree, so not much Cub work planned. But at least Christmas Break is right around the corner.

With the Touch Control block, you might want to see if there is ANY indication of leaking from the control rod. It is fairly easy to pull it out toward the front, and replace the one o-ring there (TM Tractors has it). It's much more involved once the block is reinstalled! Also check the boots & replace, if needed. There are new leather ones as well as rubber ones available.

You are probably already aware, but when you are painting the panel & clutch housing, make sure the mating surfaces are clean of dirt, primer and paint. That is a grounding path.

Great work by you guys...want to rent out your daughters for some more tractor work?! They are getting well trained, and I currently have 3 waiting for work!! :lol:
