Running-in operation
Whenever moving parts have been replaced, it
is necessary to run-in both the compressor and
the magnetic clutch.
Compressor running-in
Reassembled compressors must be run-in after
the leak test (see next page).
1. Check that the compressor contains the
specified amount of oil.
2. Install the compressor on the test bench.
3. Install the high pressure connector (T44375C)
and the low pressure connector (T44373C)
to the ports and tighten the bolts to the
specified torque.
Specified torque: 20 ~ 24 N·m
{2.0 ~ 2.4 kgf·m, 14 ~ 17 lbf·ft}
4. Connect the two connector ports using a
flexible hose.
5. Run the compressor at 1,000 rpm for at
least 30 minutes.
6. Replace the oil.
7. Repeat the leak test.
Magnetic clutch running-in
1. Install the clutch on the compressor.
2. Install the compressor on the test bench,
and operate the compressor by running the
system.
3. Maintain the compressor speed at 500 rpm.
Operate the A/C switch through the ON/
OFF cycle at least 50 times (
“
ON
”
for 10
seconds and
“
OFF
”
for 10 seconds).
ON
OFF
(50 times)
CAUTION!
While the compressor is being run-in in step
5 above, check the outside temperature of
the front head. If the temperature exceeds
80°C (176°F), stop the running-in operation.
Resume the operation when the head has
cooled.
