Kia Niro: Clutch System / Clutch Cover And Disc Repair procedures
1. |
Remove the hybrid motor assembly.
(Refer to Hybrid Motor System - "Hybrid Motor Assembly")
|
2. |
Remove the clutch cover assembly and clutch disc after loosening the
bolts.
|
Be careful not to be bent or twist bolts. Loosen bolts in diagonal directions.
|
1. |
Inspect diaphragm spring wear which is in contact with a concentric slave
cylinder bearing.
|
2. |
Check the clutch cover and disc surface for wear or cracks.
|
3. |
Check the clutch disc lining for slipping or oil marks.
|
4. |
Measure the depth from a clutch lining surface to a rivet. If the measured
value is less than the specification below, replace it.
Clutch disc depth (A): 6.4 ± 0.2 mm (0.2519 ± 0.0078 in.)
Clutch disc rivet depth (B): 0.3 mm (0.0118 in.)
|
|
• |
If reinstalling used cover, the cover should be installed with
its clutch disc as a set.
|
• |
If you only replace a disk, the adjustment ring may malfunction,
resulting in a slip due to the initial decrease of clamp load. (This
is because the clutch cover is adjusted by as much as the amount
of its wear.)
|
• |
If you only replace a disk, the disk may exceed its acceptable
thickness for assembly, making it difficult to block the driving
force.
|
|
1. |
Apply grease on a disc spline part and hybrid motor input shaft spline
part as required.
•
|
When not applying: Excessive wear of splines and bad
clutch operation can occur.
|
•
|
When excessively applying: Grease can be scattered by
centrifugal force which can contaminate the clutch disc.
This can cause a loss of friction force causing a slip.
|
|
|
2. |
The 'T/M SIDE' marked surface should face the transaxle.
|
3. |
Install the clutch disc and the cover with SST (09411-1P000, 09411-G2100).
|
4. |
Install the clutch cover bolts.
•
|
Loosely tighten every clutch cover bolts, then torque
to specifications in a diagonal direction.
This can prevent twisting, vibration of the cover, and
the lifting of the pressure plate.
|
•
|
Install the all the components with the specified torques.
If not, the clutch torque transaxle may have concerns or
the mounting bolt can loosen.
|
|
|
5. |
Install the hybrid motor assembly.
(Refer to Hybrid Motor System - "Hybrid Motor Assembly")
|
6. |
After replacing the concentric slave cylinder assembly, operate the followings
in order using GDS / KDS equipment.
(1) |
Engine clutch inspection line learning and diagnostic information.
|
(2) |
Removal of air from engine clutch hydraulic pressure line
• |
When using vacuum pressurized hydraulic fluid
injection device, change maximum vacuum pressure
to 2.5 torr and injection pressure to 2.3-2.5 bar.
|
• |
If it is impossible to inject hydraulic fluid
using the above condition, be sure to remove air
from the hydraulic line of the engine clutch at
a temperature between 0 - 40°C.
|
|
|
(3) |
Engine clutch/motor resolver adaptation.
|
(4) |
Stabilization of the engine clutch hardware transfer torque.
