PROCEDURE
ADJUST COMPRESSOR OIL LEVEL
When replacing the compressor with a new one:
| *a | Drain bolt (washer) |
Gradually discharge the inert gas from the service valves.
Remove the drain bolt (washer).
| *a | Removed Compressor |
| *b | Amount of oil drain from removed compressor |
| *c | Amount of oil remaining in the reserve chamber (60 cc (2.03 fl.oz)) |
Drain the following amount of oil from the new compressor before installation so that the amount of oil contained in it is the same as that in the compressor to be replaced.
Tech Tips
New compressors are filled with sufficient oil for the whole air conditioning system. Therefore, it is necessary to drain oil from the new compressor to compensate for oil remaining in the condenser and cooling unit.
| Standard |
|---|
| (The amount of compressor oil inside a new compressor assembly with pulley: 100 (+15) cc (3.38 (+0.51) fl.oz)) - (The amount of compressor oil remaining in the removed compressor assembly with pulley) = The amount of compressor oil to be removed when replacing the compressor assembly with pulley |
Note
When A + 60 cc (2.03 fl.oz) exceeds the standard oil fill volume specified for the compressor by part number, install the compressor without adjusting the oil volume.
Example:
If A = 45 cc (1.52 fl.oz), A + 60 cc (2.03 fl.oz) = 105 cc (3.55 fl.oz). If the standard volume is 100 cc (3.38 fl.oz), install the compressor as is.
If the amount of oil remaining in the removed compressor is too low, check for oil leaks.
Use ND-OIL 8 or equivalent for compressor oil.
Install the drain bolt (washer).
If draining the oil is difficult, drain the oil using the following procedure:
Remove the suction seal cap.
Lightly shake the compressor with the suction port facing down, and drain the oil (*1).
Note
Do not allow the pulley to come into contact with the compressor oil.
With the DL pulley facing down, rotate the pulley in the direction shown by the arrow 10 times at a rate of approximately once every 2 seconds (*2).
CAUTION:
If the pulley is rotated, refrigerant or oil might spray out. Thus, keep your face away from the compressor port.
Rotate the pulley once in the direction shown by the arrow while quickly turning the compressor so the pulley is up (*3).
Proceed with the above procedure (*1) and drain the oil (*4).
Drain the oil by repeating the procedures above approximately 5 times (from (*2) to (*4)).
INSTALL COMPRESSOR ASSEMBLY WITH PULLEY
Using an E8 "TORX" socket wrench, temporarily install the compressor assembly with pulley with the 2 stud bolts.
Tighten the 2 stud bolts.
Tech Tips
Tighten the stud bolts in the order shown in the illustration.
Install the compressor assembly with pulley and bracket with the 2 bolts and 2 nuts.
Tech Tips
Tighten the bolts and nuts in the order shown in the illustration.
CONNECT NO. 1 COOLER REFRIGERANT SUCTION HOSE
Remove the vinyl tape from the No. 1 cooler refrigerant suction hose and compressor assembly with pulley.
Sufficiently apply compressor oil to a new O-ring and the fitting surface of the compressor assembly with pulley.
| Compressor Oil |
|---|
| ND-OIL 8 or equivalent |
Install the O-ring to the No. 1 cooler refrigerant suction hose.
Connect the No. 1 cooler refrigerant suction hose to the compressor assembly with pulley with the bolt.
CONNECT NO. 1 COOLER REFRIGERANT DISCHARGE HOSE
Remove the vinyl tape from the No. 1 cooler refrigerant discharge hose and compressor assembly with pulley.
Sufficiently apply compressor oil to a new O-ring and the fitting surface of the compressor assembly with pulley.
| Compressor Oil |
|---|
| ND-OIL 8 or equivalent |
Install the O-ring to the No. 1 cooler refrigerant discharge hose.
Connect the No. 1 cooler refrigerant discharge hose to the compressor assembly with pulley with the bolt.
Engage the clamp.
Connect each connector.
Connect the wire harness with the bolt.
