Seeking 1940-1941-1942 Packard air conditioning literature that states the c.i.d. (cubic inch displacement) of the Servel-equipped air conditioning compressor.

Thanks,

And if anyone has a compressor, I need the whole darn thing. Will pay any fair market price. Thank you.

Those early compressors were re-purposed cold-room air-conditioning compressors, with some minor modification for automotive mounting. I've often wondered how many of those old cold-room compressors have been tossed into the recycle heap? I also wonder how many vintage cold-rooms may still have original compressors intact.

Sorry I'm no help with the original question.

Dave. About 10-15 years ago I had a NOS compressor without any dates stamped on on the boss. Sold it for $500 at the time. That was about market price for it, but I still kick myself for selling it. A year or so after I sold it, I bought a trunk-unit evaporator, and after that I had a reproduction compressor mount. About the only extra piece I've never had in my possession was the dual fan-belt pulley.

Is this an original compressor? It looks odd to me with its V design but it does fit the factory 1941 bracket and has the appropriate pulley so I'm wondering if maybe the type most commonly seen wasn't the only one used or if there was a later replacement of this style.

I only recall seeing two factory AC installations on 1941 Packards, Steve Wolf's 180 LeBaron Sport Brougham and Dwight Heinmuller's 180 1442 touring sedan. I have pictures somewhere of the compressor installations and haven't been able to find them yet, but they were certainly not V-twins such as PackardDon has just posted.

No. The "V" design is from the 1950s. Here's the one on my car.

I need to get a correct heater pipe for my car. I believe this is the way it's suppose to run.

Moot point now, but I did find them. These from the ex-Dwight Heinmuller 1907-1442.

Here is the somewhat blurry photo of the A/C compressor in the engine compartment of a '41 120 sedan auctioned years ago. Since it was an unrestored car, this may show better how the factory installed the unit.

I am a bit curious about compressor differences. Probably all about the same capacity but looking at the 40 and 41-42 AC parts lists the part numbers would indicate 6 different compressors were used. Different tubing runs but except for 40 the remaining compressor illustrations appear similar in shape and tubing port locations so wonder what was changed.

The illustrations also seem to indicate that the Clipper compressor mounted on the left engine side would appear to be mounted above the head as was the conventional body compressor located on the right side. A past thought of maybe it was moved to the left away from the manifolds to enable lowering it below the head for added clearance due to the Clipper hood doesn't seem to be valid. Would sure be nice to see photos of a Clipper compressor install to know for sure if it was lowered. The known AC Clipper in Texas has been converted to a Sanden so no photos available there.

Interesting in this post and others that almost all the AC cars mentioned and photographed over the years appear to be conventional bodies. Does anyone care to speculate on a reason why so few Clippers seemed to have the option vs conventional bodies. Did the people who could afford AC just not buy Clippers or was the Clipper sales volume overall just not that big in comparison?
