Lubricant Adjusting Procedure for Compressor Replacement
INFOID:0000000010999982
1.
Drain lubricant from removed compressor and measure lubricant amount.
• Remove drain bolt
, and then drain lubricant from drain port.
• 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 and con-
denser & liquid tank assembly [m (Imp fl oz.)] [D = 60 (2.1),
α
= 5 (0.2)]
110 (3.9)
−
[60 (1.6) + 20 (0.7) + 5 (0.2)] = 15 (0.5)
3.
Tighten drain bolt to the specified torque.

components that are removed except com-
pressor

INSPECTION PROCEDURE
1.
Connect recovery/recycling/recharging equipment (for HFO-1234yf) or manifold gauge.
2.
Start the engine, and set to the following condition.
Test condition
3.
Maintain test condition until A/C system becomes stable. (More than 15 minutes)
4.
Check that test results of “recirculating-to-discharge air temperature” and “ambient air temperature-to-
operating pressure” are within the specified value.
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
.
