ELECTRIC VARIABLE VALVE TIMING MOTOR/DRIVER REMOVAL/INSTALLATION [SKYACTIV-G 2.0]

WARNING:

• A hot engine can cause severe burns. Turn off the engine and wait until it is cool before servicing.

CAUTION:

• Applying excessive force (force of 100 N {10.2 kgf, 22.5 lbf} or more) to the electric variable valve timing motor/driver may cause a malfunction. When servicing, be careful not to apply excessive force to the electric variable valve timing motor/driver using other parts or tools.

• Do not disassemble the electric variable valve timing motor/driver because it is a precision unit.

1. Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION.)

2. Remove in the order indicated in the table.

3. Install in the reverse order of removal.

1	Electric variable valve timing motor/driver connector
2	Electric variable valve timing motor/driver (See Electric Variable Valve Timing Motor/Driver Installation Note.)
3	O-ring

Electric Variable Valve Timing Motor/Driver Installation Note

1. Install a new O-ring to the O-ring installation groove of the engine front cover.

CAUTION:

• To prevent damage to the electric variable valve timing motor/driver, do not apply excessive force (force of 100 N {10.2 kgf, 22.5 lbf} or more) to the shaded areas shown in the figure.

2. Install the electric variable valve timing motor/driver using the following procedures.

NOTE:

• The eccentric shaft on the electric variable valve timing actuator side can be rotated to the left and right.

  

• The electric variable valve timing motor/driver can be assembled with the joint groove of the eccentric shaft in any position, and it will not lead to vehicle damage or performance reduction.

a. Before installation, rotate the joint on the end of the electric variable valve timing motor/driver so that it is aligned to the joint groove on the electric variable valve timing actuator side.

b. Engage the joint on the end of the electric variable valve timing motor/driver with the joint groove on the electric variable valve timing actuator side.

c. Attach the seal surface.

d. Tighten the electric variable valve timing motor/driver installation bolts.

Tightening torque

• 20—26 N·m {2.1—2.6 kgf·m, 15—19 ft·lbf}
