I have a vendo 63 that cools cold but the compressor is noisey. I have a 70's vendo can machine that has a very quiet compressor and cools fine. The tags read the same. Is the any problem with swaping these out ? I don't think there would be , thought I would check befor I started. Thanks

Hello,
If the tags are the same there should not be any problem.
One thing to remember is that both machine probably have R-12 refrigerant in them, if you have any way to recover it that work out the best. If not you can use some of the newer refrigerants.

Compressors are very interchangable although you
may need to drill a few new mounting holes. There should
be no need to dump the freon or refill it during this process
Some compressors feed their copper lines up through
to the left side of the cold compartment and others to the
right so they are not real compatable.
Also, the evaporators in the can vending machines
are usually shorter and wider than slant shelf units and
may interfere with your bottle stack.
Wiring will be the same. Trust only your tape measure

Amazing enuff they where the exact same units I just had to transfer a couple srouds that were different on the can unit everything else was the same. After insalling the unit in the 63 everything worked great and quiet went to check on it and the compressor was very hot to touch. I unpluged it and checked it later after cooling off and what had happened is the fan had stoped working for some reason? I guess I'll have to check the connections or get another fan

You have 2 more fanmotors. They are on your loud compressor,
(unless they were the reason it was loud).

Got everything changed over fans all working now. Question how hot does the compressor motor get while running? What's normal ?If I touch it after it shuts down it's hot to touch but not to hot that I can't keep my hand on it. Also what causes a compressor to be noisey, This machine is a queen anne and is for indoor use only. Everything inside looks like brand new, but the comressor was noisey. Anyway it's purring like a kitten now, very quiet

Most compressors can get quite warm to the touch when running normal, but as you mentioned earlier when the compressor fan motor was not working and was to hot to keep your hand on, that is not good.
Noisey compressors can be caused by a number of things, such as the way they are mounted to the condensor deck, mounting springs inside of the compressor shell could be broken letting the pump rub on the interior of the shell just to mention a few.

The compressor came out of a vendo queen anne that has been inside it's whole life and is in mint condition other than the noise. Is this worth keeping as a spare and is it repairable? It cools just fine .How much would it cost to have the noise repaired

If the noise is comming from the inside of the compressor itself, you
can't fix it without replacement. Bob's right, the inside of the compressor is like a 2 stroke motor with a crank, rod, piston, valve plate, etc. The block is suspended by a set of springs, usually 2 or 3 on the inside. If a spring breaks, the result will have the compressor block kick over and rub the inside of the can itself.
The other problem is with the wrist pin, in the rod assembly. Just like a car motor, a compreessor rod can go south creating "slap" and causing a knock or rattle as well.
If the compressor unit came from a Queen Ann machine, put it back, keeping it original and repair the other unit. The Queen Ann is worth quite a bit more than a standard vendo 63, and you want to keep it complete.

I pulled a unit from a 70's vendo can machine that was the same compressor tag as the queen anne and all I had to do was change the condenssor shroud plates. How would I go about fixing the one that came out of the Queen Anne? Just have the compressor replaced with a new one? Would you updated with r134?
