Some of you may have seen the Mighty Mite that Bruce D. listed for sale for his friend. Even though it was real rough, I decided to pick it up since I have a parts tractor. First the bad. Most of the original paint is now replaced with rust and some parts will not be able to be restored. The steering column and front axle are bent and need to be replaced. The seat, engine tin, brake bands, and some other small parts are rusted beyond repair. I disassembled half of the rear end and the pinion shaft is twisted at the spline. You can see the twisted spline on the pinion shaft next to the replacement pinion shaft in the pic below. I should know the condition of the other pinion shaft tomorrow.
Now the good! The engine turns freely and the bore and piston look great. The crank pin and connecting rod are worn just beyond reject specs, but I have a replacement crank and NOS connecting rods and rings are available. I tested the coil and condenser in another engine and they produce great spark. The coil is dated August of 1948. The rear end gears and bearings are in great shape and I have pinion shafts I can use if both turn out to be twisted. The rear axles and hubs are in good usable condition and just need to be cleaned. The Twin Disc clutch is now functional, but the clutch disc and driving ring will need replacement due to wear and they are available. The transmission now shifts and works on all gears, but it needs to be disassembled, cleaned, and inspected. The hood is in good shape and the original front rims are restorable. I believe the rear rims are m38 Jeep rims, 4.5x16 so they will get replaced.
All in all it was a good buy, but restoring it would be very difficult without the parts tractor. I'm still deep into restoring the other Mighty Mite, so I'm just disassembling this one to see what will be needed when the time comes to restore it. Thanks for listing this one, Bruce.

Your other Mighty Mite has my interest and I am curious to see how you do with this one. On the frame it is a little hard to tell but on the u shaped piece at the nose is it welded to the straight frame rails or is the frame rail one piece that is bent to form the u shape?

The U shaped piece is cast and welded to the frame rails. Here is a better pic of how the frame rail is welded to the cast nosepiece. The restoration of the other Mighty Mite is slow going due to my work schedule and the holidays, but I will continue to post updates as I move along. I was finally able to order the original type spark plug wire, so I can finish assembling the engine. I also picked up a section of 1-1/2" exhaust pipe so I can modify the air cleaner tube to work on the Mighty Mite. Here is a pic I found of what I believe to be the correct air cleaner tube for the Mighty Mite.

Found a seat in much better condition! It will take some work to bring it back, but at least it's in much better condition than the one on the tractor.

I picked up a few NOS Twin Disc clutches, so I can replace the entire clutch on this tractor now...piece by piece.
