COMPRESSOR(for 3ZR-FE, 3ZR-FAE) INSTALLATION

PROCEDURE

1. INSPECT COMPRESSOR OIL

   1. When replacing the compressor assembly with a new one, gradually discharge the inert gas (helium) from the service valve, and drain the following amount of oil before installation.

      Note:

      • If a new compressor assembly with pulley is installed without removing the same amount of compressor oil as is remaining in the pipes, the amount of compressor oil will be excessive. This prevents heat exchange in the refrigerant cycle and will cause a refrigeration failure.

      • A certain amount of compressor oil remains in the compressor assembly with pulley during circulation and the compressor may be damaged if the amount of compressor oil is more/less than this amount. Therefore, make sure to adjust the amount of compressor oil correctly.

      • If the amount of compressor oil remaining in the removed compressor assembly with pulley is too low, check for compressor oil leakage.

      • Do not race the engine before replacing the compressor assembly with pulley.

      • for HFC-134a(R134a): Make sure to use ND-OIL 8 or equivalent compressor oil.

      • for HFO-1234yf(R1234yf): Make sure to use ND-OIL 12 or equivalent compressor oil.

   2. 

      *A	for 3ZR-FE
      *B	for 3ZR-FAE

      Remove the drain bolt (seal washer) from the removed compressor assembly with pulley.

   3. Drain the compressor oil from the oil port of the removed compressor assembly with pulley as shown in the illustration and measure the removed oil as quantity B.

      

      *A	for 3ZR-FE	*B	for 3ZR-FAE
      *a	Turn clockwise	-	-

      Note:

      • Make sure to drain the compressor oil from the oil port.

      • Keep your face away from the compressor port because turning the pulley may cause gas or oil to spray out.

   4. Calculate oil quantity C by subtracting oil quantity B, measured in the previous step, from oil quantity A (70 cc (2.37 fl.oz.)), which is the amount of oil in a new compressor assembly with pulley.

      

      *1	New Compressor Assembly with Pulley	*2	Removed Compressor Assembly with Pulley
      *a	Oil quantity A (70 cc (2.37 fl.oz.))	*b	Oil quantity B
      *c	Oil quantity C	-	-

   5. Remove the drain bolt (seal washer) from a new compressor assembly with pulley, drain oil quantity C from the oil port, and use the amount of oil remaining in the compressor assembly with pulley as the standard value.

      Tip:

      • Make sure to drain the compressor oil from the oil port.

      • Make sure to add the compressor oil from the oil port, not from the discharge or intake port.

      • If a tool is used to add compressor oil to the new compressor assembly with pulley, make sure that it is free of foreign matter.

      • If the amount of compressor oil remaining in the removed compressor assembly with pulley cannot be estimated because the compressor was damaged and oil was discharged due to a frontal collision, etc., install the new compressor assembly with pulley without removing any oil. If the condenser with receiver assembly is also replaced, do not add the specified oil for condenser with receiver assembly replacement (40 cc (1.35 fl.oz.)).

   6. Install the drain bolt (seal washer) to the new compressor assembly with pulley.

      Tip:

      The drain bolt (seal washer) can be reused.

      Note:

      Make sure that there is no damage or foreign matter on the seal washer edge.

2. INSTALL COMPRESSOR ASSEMBLY WITH PULLEY
