Really enjoyed watching you work on this old marvelous piece of equipment. My inquisitive mind wishes I could be your student. So much wonderful stuff to know.
David it wouldn't be the worst idea in the world to put some basic service valve-charge info. in that unit for future amateurs.... Just a concise explanation of the service valves operation and possibly a diagram-illustration...
I love the way you carefully fit that expansion valve back in there like that. That's some nice handiwork. Hopefully we'll get to see it all together and working, making ice cold water? ;) For belt drives that I want to be quiet, I like the cloth wrapped belts. They're also excellent on the Corvairs, as they do not flip over they way the raw edged belts sometimes can.
Thanks, on that TXV. It took some thinking and careful brazing to make that happen. I'm pleased with how it worked out. We're missing the decorative cover for the agitator, so I don't know exactly how much room will be available for things in front of the motor. However, there is no way the cover will interfere with that corner area. Hopeful to get an original cover some day. As for seeing it work in the tub of water, yes. I didn't go into details in the video because the owner hadn't made a decision as to whether or not to have the cabinet painted. After this video was made, he did decide to have it painted. It was taken to the paint shop a couple days ago. Once it's back and assembled, there will be a conclusion video with the whole cooler working. You have a good point about the cloth wrapped belts. This one is actually a wrapped belt, if I am seeing it properly. It doesn't have the visible fibers along the top edge, and also has a fabric appearance across its sides. I talked to another old-timer who told me to put a very thin film of grease on this belt. He explained that it will help the belt break in and the noise won't come back. I ran the unit for about an hour after this, and it was dead-silent. I am concerned the noise might, eventually come back. I'm still not totally convinced that the belt is correct for this sheave. It does "look like it fits" but I am accustomed to seeing more exposed sheave groove above the belt. I think a narrower belt might be more appropriate.
@@douro20 FHP is not a name brand, it is a type. Typically, it would be a Gates brand, but Browning may have offered them, too. From what I can tell, all belts come from the same factory anymore. The "linkbelt" style that can be made to any length by removing links may be as close to FHP as we can get nowadays.
Thanks to both you for the comments. I talked to an "old timer" who recommended a very conservative film of grease on the sides of the belt. This worked and the belt has remained silent since. The cooler has been in operation for several weeks now. It seems the grease softens the outer most layer of the belt and allows it to better mesh with the sheaves. This works on low HP drives where slipping is not going to be a factor, such as this 1/4 HP motor. I wish I could get a softer FHP belt but for some reason those are not easy to get; particularly in certain sizes.
@@davida1hiwaaynettoo bad I live in Germany and shipping is a nightmare. I have a store for industrial stuff in my neighborhood and they make custom belts. They aren't that expensive, too. I had a belt for a washing machine made some time ago (it had a totally weird length and had to be conductive) and they charged me about 40 bucks. That was indeed cheaper than the original belt (which wasn't available at that time).
These early belts were often designed to be lubricated with oil. They perform best with a thin film of oil on the outer jacket. I would hesitate to put brake fluid on these since it is harmful to paint. The cabinet has a new paint job and any slinging of brake fluid could be bad.

Hi Walter. The original refrigerant was Freon-12 (dichlorodifluoromethane.) This machine is suitable for use with R-152A (1,1,difluoroethane.) This has been charged with R-152A.
A beautiful job David!
Thanks!

That's a good idea!
Interesting. I have never used flare gaskets, except for maybe a copper one or two, in my life.

Amazing job David!! Very happy to watch and learn from your videos!
Thank you!
Good project.
Thanks!
You may need to find an FHP belt (fractional horsepower). but good luck, I haven't been able to source any as of late.
How about Browning belts?

@@kc5gym Yeah I knew it was a type of belt, and Browning makes belts specifically for fractional horsepower applicatios.

Instead of belt dressing use some old school DOT3 or 4 brake fluid on your belts.
