*a	20 mm (0.787 in.)
*b	1.0 mm (0.0394 in.)
*c	1.4 mm (0.0551 in.)
*d	3.0 mm (0.118 in.)
*d	2.0 mm (0.0787 in.)

Seal packing:

Toyota Genuine Seal Packing 1281, Three Bond 1281 or equivalent

NOTICE:

Start applying seal packing within range (A).
Make sure that the clearance from the center of the bead is within 1 mm (0.0394 in.).
Apply seal packing in a continuous bead 2 to 3 mm (0.0787 to 0.118 in.) in diameter.
If there is an area where seal packing is not applied in a continuous bead, be sure to apply seal packing by overlapping the ends of the bead at least 10 mm (0.394 in.).
Stop applying seal packing after allowing it to overlap with the beginning of the bead by at least 10 mm (0.394 in.) within range (A) in the illustration.
Install the electro magnetic control coupling sub-assembly within 10 minutes after applying seal packing. If the electro magnetic control coupling sub-assembly is not installed within 10 minutes after applying seal packing, completely remove and then reapply seal packing.
After installing the electro magnetic control coupling sub-assembly, do not immediately add oil or drive the vehicle for at least 1 hour.

(d) Install the electro magnetic control coupling sub-assembly with the 4 bolts.

Torque:

20 N·m {200 kgf·cm, 14 ft·lbf}

NOTICE:

Do not damage the diaphragm oil seal.
Do not damage the contact surface of the rear differential carrier assembly and electro magnetic control coupling sub-assembly.

(e) Connect the electro magnetic control coupling sub-assembly connector and vacuum hose.

NOTICE:

Do not damage the electro magnetic control coupling wire harness.
