Enough with my detour to rescue a couple newer fridges! I am back to the prewar models that have a sense of style. This luscious object came from the other side of my state. It's a 1936 Norge possibly. It has the belt driven rollator compressor. Cosmetically, it's very nice. It was said to have worked five years ago. The wiring was jacked up and the motor was disconnected. Fortunately, I found the unit springs. After Ray and my innocent neighbor got it off the truck, Ray and I attacked it. We got the springs installed. The motor junction block had three studs. They were cryptically marked. I also checked resistance. I clipped my test cord on it and away it went, chuga chuga chuga. Unfortunately, it doesn't cool. You could hear something, just no cooling. I have asked Gill if he has a Norge serviceman hat.

Travis, you HAVE to take a picture of that drawn representation of the rollator compressor that is on the freezer door. It is so cool!
I can confirm. It does go chugga chugga. It also changed its tone during the run slightly and started to develop the slightest knock. Nothing alarming to be sure. What a fascinating and strange machine. It's SO2 and it may have either a high or low side float in the evaporator header. Kind of like a very old type of Frigidaire evaporator...which Travis also has at the moment.
The compressor is an interesting one for a belt drive and Norge was proud enough to put a hand drawn picture of the compressor on the evaporator door. If I had to have a belt drive from back then...this might have been the one. Who knows how reliable they really were. It is a rotary compressor or a rolling piston compressor. Frigidaire ties back into the story from the simple fact that their meter miser compressor that they used for most of their history is that same type (as far as I can tell). I think I smell a rat. If Norge made this compressor first, which I think they did, they got ripped off by Frigidaire a few years later. Improved, I mean they improved the design. At least Frigidaire had the foresight to make their design hermetic.

That is one real nice looking Norge, I just sold a rusty 48 for $50, need the room. I will be checking my books, I am sure there is enough info in them on the Rollator to make a hat. I am going to have to find time this fall or sooner to stay the weekend and do some serious work.

Nice! I started reading about their compressor. The fact that the rollator was invented by somebody named "Roloff" was amusing. I wonder if the name was intended to be whimsical? away it went, chuga chuga chuga. Is it supposed to "chuga chuga"?

Yes, I've never heard a belt drive unit run as silently as a hermetic. I haven't checked the condition of the belt yet. That will be another mind blowing moment for the guys at NAPA!

Hi, yes. Could I get a replacement belt? Sure, it's a 1930s Norge refrigerator? Oh, you don't have that in stock? Grab a belt for an Austin Healey bug eye sprite and we will call it good.

Nah, tractor supply. Probably matches a '93 cub cadet mower deck.

That's very cool. I've never seen a link belt.

That's very cool. I've never seen a link belt. I have never used one, pricey.

Those adjustable belts are cool, but they're over-kill in this application. There's a belt tensioner on the thing. Belts are sold by width, the L number and length.
Speaking of belts, I have to order springs for the Universal fridge with the belt driven unit. The same one that Doug did a wonderful job modifying the sheave.

I have never been a fan of link belts. However, I have had to use them. Some industrial machinery is designed to be very maintenance unfriendly and can require a tremendous amount of disassembly to replace a belt. A "link belt" can be installed much like you would install a bicycle chain, meaning assembled around the obstructions, and save a ton of disassembly to get a machine up and running.

I'm a bit disappointed in Travis's response. When asked "Is it supposed to "chuga chuga"?" I honestly expected Travis to say "How the hell should I know, what am I Mr Rollator?" It looks like a Rollator is just a standard rotatory compressor? I couldn't find a patent.
