Toyota Venza: Reassembly

REASSEMBLY

PROCEDURE

1. INSTALL MAGNETIC CLUTCH ASSEMBLY

(a) Install the magnetic clutch stator while aligning the protrusion on the stator with the notch on the air compressor assembly as shown in the illustration.


(b) Engage the clamp.


(c) Install the bracket with the screw.

(d) Connect the connector.

(e) Using a snap ring expander, install a new snap ring with the chamfered side facing up.

NOTICE:

  • Do not expand the snap ring by more than 35.5 mm (1.39 in.) when installing it.
  • Do not damage the seal cover of the bearing when installing the snap ring.

(g) Install the magnetic clutch washers and magnetic clutch hub.

NOTICE:

Do not change the combination of the magnetic clutch washers used before disassembly.

(h) Using SST, hold the magnetic clutch hub and install the bolt.

SST: 09985-00270

Torque:

18 N·m {184 kgf·cm, 13 ft·lbf}

NOTICE:

Make sure that there is no foreign matter or oil on the compressor shaft, bolt and clutch hub.


2. INSPECT MAGNETIC CLUTCH CLEARANCE

(a) Set the dial indicator to the magnetic clutch hub.


(b) Connect a positive (+) lead from the battery to terminal 1 of the magnetic clutch connector, and a negative (-) lead to the ground wire. Turn the magnetic clutch on and off and measure the clearance.

Standard clearance:

0.26 to 0.60 mm (0.0103 to 0.0236 in.)

If the measured value is not within the standard range, remove the magnetic clutch hub and adjust it with magnetic clutch washers.

NOTICE:

Adjustment should be performed with 3 or less magnetic clutch washers.

(c) Remove the compressor and magnetic clutch from the vise.

3. ADJUST COMPRESSOR OIL LEVEL

(a) When replacing the compressor and magnetic clutch with a new one, gradually discharge the refrigerant from the service valve, and drain the following amount of oil from the new compressor and magnetic clutch before installation.

Standard:

(Oil capacity inside the new compressor and magnetic clutch: 130 + 15 cc (4.4 + 0.51 fl.oz.) ) - (Remaining oil amount in the removed compressor and magnetic clutch) = (Oil amount to be removed from the new compressor when replacing)

NOTICE:

  • When checking the compressor oil level, observe Precaution on the Cooler Removal/Installation.
  • If a new compressor and magnetic clutch are installed without removing some oil, there will be too much oil in the system due to the oil remaining in the pipes of the vehicle. Excessive oil in the system prevents heat exchange in the refrigeration cycle and causes refrigeration failure.
  • If the amount of oil remaining in the old compressor and magnetic clutch is too small, check the A/C system for oil leaks.
  • Be sure to use ND-OIL 8 or equivalent for compressor oil.
