KIA Niro: Clutch Cover And Disc Repair procedures
Kia Niro - First generation - (DE) (2017-2022) - Service and Repair Manual / Engine Clutch System / Clutch Cover And Disc Repair procedures
Removal
- Remove the hybrid motor assembly.
(Refer to Hybrid Motor System - "Hybrid Motor Assembly")
- Remove the clutch cover assembly and clutch disc after loosening the bolts.
Warning
Be careful not to be bent or twist bolts. Loosen bolts in diagonal directions.
Inspection
- Inspect diaphragm spring wear which is in contact with a concentric slave cylinder bearing.
- Check the clutch cover and disc surface for wear or cracks.
- Check the clutch disc lining for slipping or oil marks.
- 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.)
Installation
Warning
- 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.
- Apply grease on a disc spline part and hybrid motor input shaft spline part as required.
Warning
- 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.
- The 'T/M SIDE' marked surface should face the transaxle.
- Install the clutch disc and the cover with SST (09411-1P000, 09411-G2100).
- Install the clutch cover bolts.
Warning
- 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.
- Install the hybrid motor assembly.
(Refer to Hybrid Motor System - "Hybrid Motor Assembly")
- After replacing the concentric slave cylinder assembly, operate the followings in order using KDS.
(1) Perform initialization of the engine clutch inspection line learning and diagnostic information.
