Default Semi trailer reefer motor

I have an AK that was reportedly from a 1940s or 50s reefer trailer. Are there any old time truckers that remember these units (photo attached) hanging on the front. Were they exposed to the weather like that?

It looks like that wasn't unusual.

Thermoking used Wisconsin AENL engines with large centrifugal clutches on them to run refrigerating compressors at least through the 1970s. A friend recalls rebuilding one of these engines at least five times since it wore out two cast iron sleeves. He said it must have had many thousands of hours of run time on it. I do not recall ever hearing about an AK on a reefer trailer. The older units like Wayne posted were usually a small cast iron Briggs & Stratton with a fan mounted on the crankshaft. I have seen them as model B's, Z's and 23's. I have never seen one setup like that with a Wisconsin until now. I would love to see some pictures of the engine you have and how it is setup.

When I worked on Thermo Kings, they were Mercedes Benz (older ones) or Isuzu (newer ones).

I have an AK from a reefer truck, I think but am not sure it was a ThermoKing brand.
