I greatly enjoy the authenticity of your repairs and seeing how you troubleshoot and modify things as you go. As you tear into these old motors, you never know what you will find. Thank you for taking the time to document this!

Thanks for this series. I meddle in my home shop with old tools. Years ago I found for cheap a “GE Workshop” or some such. It had a failed centrifugal switch and a dried out capacitor. Looked but never found a video on these kind of repairs. Heading out for a business trip this morning but looking forward to revisiting that motor on my return. Thanks for your time and patience to document your thoughts and actions.

I expect you can use a potential relay to replace the centrifugal switch. Will depend on the motor voltage rating. Need to chose the correct one which trips at the correct voltage. This Mars 63 relay trips at 139 to 153V, which is the lowest voltage model they sell. It is generally good for smaller 120V motors. The capacitor and winding resonance generate a voltage higher than the line voltage when the motor is at speed, hence the rating.

Now a nice paint job to complete it

The 1/4hp high-slip Delco motor I worked on once ran whisper quiet when it was done running up. It needed a 170mfd capacitor.

Nice! My kitchen belt-drive fridge has a 1/4 HP Delco probably similar to what you describe. They do run quietly when working correctly. Very little magnetic whine or vibration.

I always learn something from your videos, and in this one I realizez I needed to buy a crimper and some ferrules.

Very good tool to have!

For the odd balancing I do, I use a Dubro model airplane propeller balancer. They're cheap and simple. Just a set of low resistance rollers. I mounted mine to a plank of wood with several mounting holes to vary the shaft length it can be used for. That rotor is probably way too heavy for it, but I bet it would work anyway. I have used it on smaller motor rotors.

Those are very well made motors. Waaay more efficient than any modern motor, so the new manufactures give themselves more credit than theyre worth. I got an old lathe with 2 old induction and brushed motors, they work just like new. No ball bearings so simpler and cheaper, tighter tolerances, and less heat. The coils are nice and thick so it wont get too hot and, that leads to efficiency and LIFETIMES of durabilityy. Which is just where all products should be. One has a diamond lapidary wheel attached to it for grinding and sharpening whatever I need, and the other has a wire wheel on it for just general shop tasks. I get more enjoment from using those machines, more than any other god damned new chinese piece of you really dont want to know what. More tools and things need to be that level of quality and durability. Hell, it would cost manufactureres like 20 percent more in cost to make it right. They, yes the manufactueres, need to step up assembly line and product design . Consumers demand more from them, because honestly its not even balogna its crap.

@davida1hiwaaynet

Thank you! It is very well built. Delco motors were often special builds for OEM manufacturers. When they get oiled properly, they just don't wear out! I am sure that diamond saw you have has lasted and will continue to last a lifetime! We need to bring back quality, but that isn't making money for those in high places. They profit from the constant turnover, cheap and often replaced equipment, constantly buying over and over... that is the beginning of the money trail. You can follow it where you want.

Wanna see the rest of the unit restoref

I don't have a cabinet for it, unfortunately. What you see in the thumbnail is all there is.

I got to thinking while watching this, I'm sure i;ve got one of these down in my basement sitting. Years ago I was at a guys house and found an old belt drive sulpher dioxide refrigerator in his old shed. I asked if I could nab the old condensing unit and he let me. The condenser was shot but motorand compressor worked fine. The motor I think was a fifth HP capacitor delco. Has a 3 blade fan and the old compressor is still sitting down there. I played with it back then and it held pressure. At the time i replaced condenser. I remember i tested with R22 and it did work and even cooled but the head pressure was high enough it would slip the belt.

@davida1hiwaaynet

Thanks for the comment! Very good find you had there; and I understand not being able to save the whole cabinet - although it would have been nice! Yep, going from SO2 to R22 would be a huge increase in pressure! These didn't have a relief valve, but the belt tension was typically set to provide a limit on the pressure capability. As for the bad condenser; I've not seen that often. Did the fan hit it and puncture it?

It would be interesting to know exactly how they stuffed that wick at the factory,, was it just a guy doing it like you did it or a guy with mechanized mechanical assistance...... Fully mechanized somehow ?? That would be a sight !! Also do we know what that motor cost new in its day?

If I remember, some of the wicks had a long string on one or both ends, where you could pull it through by the string. I forgot to add that to my design on this build. I expect they did put these in with some automated system! Will have to look for some sort of old ads for these. Being a capacitor motor in the beginning of that era, it may have been pretty spendy.

What a fake restoration!!! Kidding of course, very excellent attention to detail, and very well presented. Also very impressive is the quality of the insulation in the windings; I would have lost the bet those windings would be in the gig range at a thousand volts; truly a testament on how things were built back in the day, and to what a disgrace things are built like today.

This was part of a Crosley fridge which had been abandoned in the woods. It had laid on its back and the cabinet was missing the door and filled with rainwater. The cabinet was totally destroyed. I have the compressor, but don't have a cabinet for it. Might repair that compressor in the future if I have a need for it.
