If you have replaced the dual clutch assembly or clutch actuator, perform
wear compensation on the clutch actuator.
(Refer to Clutch Actuator Assembly - " Adjustment ")
| •
|
If you only replace a motor, you don't need separate
adjustment. If you replace a clutch actuator with a
new one, make sure that you don't perform initialization.
|
|
|
| • |
Perform wear compensation when you have replaced the motor as
well as the dual clutch assembly or clutch actuator.
(Refer to Clutch Actuator Assembly - "Repair Procedures")
|
|
| 1. |
If you only replaced the motor, install the clutch atuator motor.
| •
|
Do not reuse a O-ring (A), and sealing bolt (B).
|
|
|
| 2. |
Check the assembled state of the dowel pins (A) before installing the
clutch actuator assembly.
|
| 3. |
Perform the clutch touch point learning procedure using the GDS.
| •
|
Even if you removed and reinstalled the clutch actuator,
be sure to perform the touch point learning.
|
| •
|
If you have replaced the dual clutch assembly or clutch
actuator, be sure to perform the touch point learning.
|
|
|
| • |
If you replaced the dual clutch assembly or clutch actuator,
be sure to perform wear compensation by referring to the following
table.
Case

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

(Refer to Clutch Actuator Assembly - "Removal")
| •
|
To measure the rod length of an old clutch actuator,
perform the steps No. 2 - 3 of the following procedure.
|
|
|
| 2. |
Install the faulty clutch actuator (A) on special service tool (09430-C1302)
and fix the actuator using nuts and bolts.
|
| 3. |
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).
|
| 2) |
Clutch actuator 2
|
| •
|
If the rod length is less than 46 mm (1.8110 in.), replace
all of the dual clutch assembly, clutch actuator, and
engagement bearing.
|
|
|
| 4. |
Remove the clutch actuator from the special service tool (09430-C1302).
| •
|
To match the rod length of a new clutch actuator with
that of the clutch actuator removed from the vehicle,
perform the steps No. 5 - 14 of the following procedure.
|
|
|
| 5. |
Install the faulty clutch actuator (A) on special service tool (09430-C1302)
and fix the actuator using nuts and bolts.
|
| 6. |

|
| 10. |
Press the end part of rod (A) and release the pressing force when you
see the nut bump (B).
| •
|
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.
|
| •

boot if the pressing force is released.
|
|
|
| 11. |
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. 3.
|
Increasing (+) rod length : Rotate counter-clockwise / once
+0.25mm (+0.0098 in.)
Shortening (-) rod length : Rotate clockwise / once -0.25mm
(-0.0098 in.)
|
| •
|
Perform the same procedure for the opposite side rod.
|
|
| •
|
Be aware not to break the clutch actuator caused by
break away inner parts when the SST over rotates clockwise.
|
| •
|
If the "length of the clutch actuator's new rod" is
not adjusted to the "length of the old rod" measured
at step No. 3, the DCT shift shock may occur or driving
may be impossible.
|
|
|
| 12. |
