Installation

INSTALLATION

CAUTION / NOTICE / HINT

NOTICE:

Change the vehicle to 2WD mode before removing the transfer shift actuator assembly.

If the vehicle cannot be changed to 2WD mode, since the new transfer shift actuator assembly is set in the 2WD position, connect all the connectors to the vehicle side wire harnesses to set the new transfer shift actuator assembly to the drive state of the vehicle before installing the new transfer shift actuator assembly.

PROCEDURE

1. INSTALL TRANSFER SHIFT ACTUATOR ASSEMBLY

(a) Apply seal packing to the transfer shift actuator assembly as shown in the illustration.

Seal packing:

Toyota Genuine Seal Packing 1281, Three Bond 1281 or equivalent

Text in Illustration

*a

Seal Packing

NOTICE:

If the removed transfer shift actuator assembly will be reused: After removing the transfer shift actuator assembly, be sure to perform the following before reinstalling it: 1) using a knife, cut off any old seal packing on the contact surface of the transfer shift actuator assembly, 2) clean off any remaining old seal packing from the contact surface of the transfer shift actuator assembly, and 3) reapply seal packing to the transfer shift actuator assembly.

(b) Install the transfer shift actuator assembly with the 4 bolts.

Torque:

9.5 N·m {97 kgf·cm, 84 in·lbf}

NOTICE:

Tighten the bolts of the transfer shift actuator assembly within 10 minutes of applying the seal packing. The seal packing will dry very quickly.

(c) Connect the 3 connectors and attach the 2 clamps.

Removal

REMOVAL

CAUTION / NOTICE / HINT

NOTICE:

Change the vehicle to 2WD mode before removing the transfer shift actuator assembly.

If the vehicle cannot be changed to 2WD mode, since the new transfer shift actuator assembly is set in the 2WD position, connect all the connectors to the vehicle side wire harnesses to set the new transfer shift actuator assembly to the drive state of the vehicle before installing the new transfer shift actuator assembly.

PROCEDURE

1. REMOVE TRANSFER SHIFT ACTUATOR ASSEMBLY

(a) Disconnect the 3 connectors and detach the 2 clamps.

(b) Remove the 4 bolts and transfer shift actuator assembly.
