6.Using the drift (A) [SST: ST30720000 (J-25405)], install front oil seal (1) as shown in the figure.





CAUTION:
- Never reuse oil seal.
- When installing, never incline oil seal.
- Apply gear oil onto side oil seal lip.
7.Install wave washer to electric controlled coupling.





8.Apply liquid gasket (1) to mating surface of coupling cover.
Use Genuine Silicone RTV or equivalent. Refer to "Recommended Chemical Products and Sealants" Recommended Chemical Products and Sealants.

CAUTION:
- Remove old gasket adhering to the mounting surfaces.
Also remove any moisture, oil, or foreign material adhering to the mounting surfaces.
- The width of sealant bend is approximately 3 mm (0.012
in).
9.Install electric controlled coupling to spline of drive pinion inside final drive assembly.

CAUTION:





- Align the pin (A) on electric controlled coupling with the groove (B) of final drive assembly.
- Be careful not to damage center oil seal.





10.Press the electric controlled coupling pin to check that it is positioned in the groove of the final drive assembly as shown in the figure.
NOTE:
If the pin is properly positioned in the groove, then the electric controlled coupling can be pressed by the same amount of flection of the wave washer.

11.Temporarily tighten reamer bolts (1) to the positions shown in the figure.

CAUTION:
- Never use tools. Always tighten by hand.
- If reamer bolts cannot be tightened all the way by hand, the electric controlled coupling pin may not be positioned in the groove of the final drive assembly. In this case, remove electric controlled coupling and reinstall it.
12.Tighten reamer bolts and coupling cover mounting bolts to the specified torque.
13.Install harness bracket, and tighten bolts to the specified torque.
14.Install torsional damper. (When torsional damper has been reused.)

1.Spray alcohol on a cotton cloth four times per part.

CAUTION:
Always use a new cotton cloth.





2.Wipe the mounting surface of electric controlled coupling five times.

CAUTION:
Complete the work within 180 seconds to prevent alcohol from evaporating.





16.Install torsional damper mounting nut, using flange wrench (1)
(commercial service tool) and tighten to the specified torque.

CAUTION:
