Inspect A/C Compressor Oil

Removed A/C compressor
Replacing A/C compressor
Amount of A
New A/C compressor
Amount of drainage = amount of oil in the new A/C compressor - amount of A
1. OIl replacement (A/C Compressor Overhaul)
(1) Measure the volume of A/C compressor oil contained in the compessor to be replaced
(amount = A)
(2) Add A/C compressor oil:
  Replacement quantity of new A/C oil = ( A + 20 cc)
HINT:
As some A/C oil will always remain in the A/C compressor after it is emptied during measurement procedure. Therefore it is necessary to allow for this when calculating the amont of oil required for the overhauled compressor, hence the addition of 20cc to the measured quantity.
 
2. Oil volume adjustment (New A/C compressor) assembly
(1) Measure the volume of A/C compressor oil contained in the compessor to be replaced
(amount = A)
(2) Drain oil for the new compressor
  Oil require for new compressor
= A
