Adjustment

Warning

If you replaced the dual clutch assembly or clutch actuator, be sure to perform wear compensation by referring to the following table.

  1. Rewinding the rod to adjust rod length (when only the clutch actuator is replaced)

Warning

  • Be sure to perform it when you have replaced the clutch actuator but reuse the dual clutch assembly.
  • It is performed to adjust the rod length of a new clutch actuator to that of an old clutch actuator.

Warning

Warning

To measure the rod length of an old clutch actuator, perform the steps No. 3 - 4 of the following procedure.

  1. Install the faulty clutch actuator (A) on special service tool (09430-F0100) and fix the actuator using nuts and bolts.

  1. Slightly pull the lever of the clutch actuator removed from the vehicle and measure the length of each old rod (C).

Length of the old rod (C) : Length from the reference plane (A) to the end of the rod (B).

  1. Clutch actuator 1
  2. Clutch actuator 2

Warning

Warning

If the rod length is less than 57 mm (2.2441 in.) replace all of the dual clutch assembly, clutch actuator, and engagement bearing.

  1. Remove the clutch actuator from the special service tool (09430-F0100).

Warning

To match the rod length of a new clutch actuator with that of the clutch actuator removed from the vehicle, perform the steps No. 6 - 15 of the following procedure.

  1. Install the clutch actuator (A) on special service tool (09430-F0100) and fix the actuator using nuts and bolts.

  1. Fix the pull rod to hook (B) and then remove sealing rubber (A).

  1. Slightly pull the lever of the new clutch actuator and measure the length of each new rod (C).

Length of the new rod (C) : Length from the reference plane (A) to the end of the rod (B).

  1. Clutch actuator 1
  2. Clutch actuator 2

  1. With the clutch actuator fixing jig (09430-F0100) (A) installed, stand the clutch actuator vertically.
  2. After standing it vertically, remove the hook (B) from the rod.

  1. Press the end part of rod (A) and release the pressing force when you see the nut bump (B).

Warning

Warning

  • Light inside of the hole (C) and check the nut bump (B) inside of it.
  • Repeat the operation if the nut bump (B) does not come down to the assembly hole position.
  • The nut bump (B) can be moved up a little by sealing boot if the pressing force is released.
  1. Insert a special tool (09430-C1300) (A) to a sealing rubber hole.

    Rotate the SST clockwise and adjust the length of the new clutch actuator's rod to the "length of old rod", which was measured at step No. 4.

Increasing (+) rod length : Rotate counter-clockwise / once +0.25mm (+0.0009 in.)
Shortening (-) rod length : Rotate clockwise / once -0.25mm (-0.0009 in.)

Warning

Warning

Perform the same procedure for the opposite side rod.

Warning

  • Be aware not to break the clutch actuator caused by break away inner parts when the SST over rotates clockwise.
  • IIf the "length of the clutch actuator's new rod" is not adjusted to the "length of the old rod" measured at step No. 4, the DCT shift shock may occur or driving may be impossible.
  1. With the clutch actuator fixing jig (09430-F0100) (A) mounted, maintain the level of the clutch actuator.
  2. With the fixing jig (09430-F0100) levelled, install the hook (B) on the clutch actuator.

  1. Slightly pull the lever of the clutch actuator and check whether the "length of the rod which the final adjustment is finished" is same with the "length of the old rod" measured at step No. 4.

Rod length (C) : Length from the reference plane (A) to the end of the rod (B).
