Removal and Installation

REMOVAL

NOTE:

• When replacing AWD control unit (integrated with actuator assembly of electro-hydraulic coupling assembly) or electro-hydraulic coupling assembly perform adjustment before removal. Refer to Adjustment.

• Before replacing electro-hydraulic coupling due to vibration and/or noise when making low speed turns, refer to TSB to assist in proper diagnosis.

Remove propeller shaft from rear final drive companion flange. Refer to Removal and Installation (CVJ-CVJ-C).

NOTE:

Tie propeller shaft aside with a suitable strap.

Disconnect harness connector of actuator assembly .

• To disconnect harness connector, the lock tab must be pulled outward.

Place a pan under electro-hydraulic coupling assembly mounting part.

Remove electro-hydraulic coupling assembly from final drive assembly after removing electro-hydraulic coupling assembly mounting bolts.

CAUTION:

Oil is drained from between electro-hydraulic coupling assembly and final drive assembly when removing.

• If necessary, use cutout to pry.

  

Remove O-ring from electro-hydraulic coupling assembly.

CAUTION:

• Never use a tool.

• Never damage electro-hydraulic coupling assembly.

INSTALLATION

CAUTION:

Be careful to place each part so that the contamination never stick to the drum surface flange during work.

Install O-ring to electro-hydraulic coupling assembly.

CAUTION:

• Never reuse O-ring.

• Apply electro-hydraulic coupling oil lightly and evenly onto O-ring.

• When installing O-ring, never use a tool.

• Never damage O-ring.

Locate aligning marking on tip of drive pinion . Rotate rear wheels until the aligning marking is aligned with the lower bolt hole , as shown in figure.

Locate aligning marking on drum of electro-hydraulic coupling assembly and align it marking with the lower bolt hole , as shown in figure.

Install electro-hydraulic coupling assembly to final drive assembly .

CAUTION:

Aligning marking on drum of electro-hydraulic coupling assembly and marking on tip of drive pinion.

Tighten electro-hydraulic coupling assembly mounting bolts to the specified torque diagonally.

• For tightening torque, refer to Exploded View.

CAUTION:

Check that electro-hydraulic coupling assembly is seated fully on final drive assembly before installing mounting bolts.

Connect harness connector of actuator assembly .

• Push lock tab inward to engage the connector.

Install propeller shaft to rear final drive companion flange. Refer to Removal and Installation (CVJ-CVJ-C).

Refill electro-hydraulic coupling oil. Refer to Adjustment.

When replacing AWD control unit (integrated with actuator assembly of electro-hydraulic coupling assembly) or electro-hydraulic coupling assembly perform adjustment after installation. Refer to Adjustment.

Adjustment

ADJUSTMENT BEFORE REMOVAL

AWD Control Unit Part Number Saving

When replacing AWD control unit (integrated with actuator assembly of electro-hydraulic coupling assembly) and electro-hydraulic coupling assembly, perform AWD control unit part number saving. Refer to Description.

ADJUSTMENT AFTER INSTALLATION

AWD Control Unit Programming

When replacing AWD control unit (integrated with actuator assembly of electro-hydraulic coupling assembly) and electro-hydraulic coupling assembly, perform programming to AWD control unit. Refer to Description.

Electro-Hydraulic Coupling Oil Filling, Air Bleeding and Initialize Oil Deterioration Level

When the electro-hydraulic coupling oil is drained, such as when replacing or removing/installing electro-hydraulic coupling component parts, the air bleeding and initialize oil deterioration level of electro-hydraulic coupling oil is required after fill with new electro-hydraulic coupling oil.

Fill with electro-hydraulic coupling oil following the instructions below.

Remove filler plug and gasket from coupling oil tank cover .

Fill with new electro-hydraulic coupling oil to specified amount.

Specified amount

: Approx. 0.6 (1-1/4 US pt, 1 lmp pt)

CAUTION:

• Use LSC Transmission Fluid 12-301 or equivalent for electro-hydraulic coupling oil.

• When using oil, allow the additives to diffuse well before use.

• Oil that has been stored for 12 months can not be used.

NOTE:

Oil level should be level with bottom of filler plug mounting hole.

Set the original gasket on filler plug, and install it to coupling oil tank cover.

NOTE:

The gasket will be replaced to new one at a later work.

Tighten filler plug to the specified torque. Refer to Exploded View.

Perform air bleeding and initialize oil deterioration level of electro-hydraulic coupling oil. Refer to Description.

Check oil level for electro-hydraulic coupling oil again.

NOTE:

The oil level may be reduced after air bleeding.

CAUTION:

Turn the ignition switch OFF while checking oil level.

• Oil level should be level with bottom of filler plug mounting hole. Add electro-hydraulic coupling oil if necessary.

CAUTION:

Never reuse gasket.
