NOTE:
 Do not allow dust, dirt, or other foreign materials to enter the gearbox.
 Make sure not to get any silicone grease on the terminal part of the connectors and switches,
especially if you have silicone grease on your hands
or gloves.
1. Remove the steering gearbox (see page 17-65).
2. Disconnect the torque sensor 3P connector (A) from the steering gearbox, then remove the wire
harness clamp bolts and the ground terminal (B). 3. Remove the EPS motor (A) from the steering
gearbox, then remove the O-ring (B) and discard it.

1. Clean the mating surface of the EPS motor (A) andthe steering gearbox.
2. Apply a thin coat of silicone grease to the new O-ring (B), and carefully fit it on the EPS motor.
3. Apply steering grease into the EPS motor shaft (C).
4. Set the EPS motor on the gearbox by engaging the EPS motor shaft and the worm shaft (D).
5. Turn the EPS motor two or three times to the right and left about 45 degrees. Make sure the EPS
motor is evenly seated on the steering gearbox,
and that the O-ring is not pinched between the
mating surfaces.
6. Loosely install the motor mount bolts(E), then turn the steering shaft two or three times to the right
and left about 45 degrees.
7. Tighten the motor mount bolts to the specified torque. 8. Connect the torque sensor 3P connector (A) to the
steering gearbox, then install the wire harness
clamp bolts and the ground terminal (B).
9. Finish the installation, and note these items:  Make sure the torque sensor 3P connector isproperly connected.
 Make sure the EPS motor and the EPS wires are not caught or pinched by any parts.
10. Install the steering gearbox (see page 17-72).
