Reply to "What is the Oil Capacity for the Original Pantera Air Conditioning?"

Brand new York compressors - out of the box - contained 10 ounces of ESA-M2C31-A oil.  Ford's part number for the oil was CAZ19577-A. That oil was supposedly equivalent to Texaco Capella E refrigerant compressor oil.

Measured with a dipstick inserted through the crankcase oil filler plug, a level of 1 inch is equivalent to 10 ounces, the maximum level.  A level of 1/2 inch is equivalent to 4 ounces, the minimum level; those figures are from my 40+ year old hand written notes.

I have old air conditioning manuals (Both Ford and Chilton) that give different numbers for the oil level readings, but I tend to trust my hand written notes because I assume I arrived at them via actual measurements. Anyway the manuals specify the oil levels of a horizontally oriented York compressor are 1-3/16 inch maximum and 13/16 inch minimum.

When measuring with a dipstick you have to be careful to angle the dipstick enough to clear the boss cast into the floor of the crankcase, exactly opposite the boss for the filler plug, or else you'll have a false low reading.

When checking oil level, the crankshaft should be rotated until the keyway in the compressor shaft is oriented towards the compressor head ... this gets the crankshaft out of the way of the dipstick (based on memory).
