LUBRICANT
Lubricant Adjusting Procedure for Compressor Replacement
INFOID:0000000010122111
1. Drain lubricant from removed compressor and measure lubricant amount.
1. Turn the compressor so that it faces downward, and drain
the compressor oil from high-pressure port (A) and low-
pressure port (B).
2. Measure total amount of lubricant that is drained from
removed compressor.
2. Drain lubricant from a new compressor that is calculated accord-
ing to the following conditions.
CAUTION:
If lubricant amount that is drained from removed compressor is less than 60 m (2.1 Imp fl oz),
perform calculation by setting “D” as 40 m (1.4 Imp fl oz).
Example: Lubricant amount to be drained from a new compressor when replacing compressor [m (Imp fl
oz)] [D = 60 (2.1),
α = 5 (0.2)]
150 (5.3)
− [60 (2.1) + 20 (0.7) + 5 (0.2)] = 65 (2.3)
3. Install compressor and check the operation.

INSPECTION PROCEDURE
1. Connect the manifold gauge set.
2. Set the vehicle, and set to the following condition.
Test condition
3. Maintain test condition until A/C system becomes stable. (Approximately 10 minutes)
4. Check that the characteristics for “intake temperature vs. discharge temperature” and “ambient tempera-
ture vs. pressure” are within the standard values.
5. When test results are within the specified value, inspection is complete.
If any of test result is out of the specified value, perform diagnosis by gauge pressure. Refer to
"Trouble Diagnosis For Unusual Pressure"
.
