Installation
   
•
If reinstalling used cover, the cover should be installed with its clutch disc as a set.
1.
Apply grease on a disc spline part and transaxle input shaft spline part as required.
Specified grease : CASMOLY L9508
Amount : 0.1 - 0.2g
   
•
When not applying: Excessive wear of splines and bad clutch operation can occur.
•
When excessively applying: Grease can be scattered bycentrifugal force which can conteminate the clutch disc. This can cause a loss of friction force causing a slip.

2.
Before installing the clutch disc, check the “TM SIDE” and “FLYWHEEL SIDE” marked on the clutch disc, and install it with the clutch cover using a special tool (09411-1P000).
   
Possible problems when the disc is installed in the opposite direction.
•
There can be an interference between the concentric slave cylinder on the transaxle side and a engine flywheel surface.
•
Transaxle shift error or a strange sound can occur due to clutch separation.
•
The concentric slave cylinder can break. If it does, the concentric slave cylinder should be replaced new one.
The 'T/M SIDE' marked surface should face the transaxle.

The 'FLYWHELL SIDE' marked surface should face the flywheel.

3.
Install the clutch disc and the cover with SST (A: 09411-1P000).

4.
Install the clutch cover mounting bolts.
Tightening torque :
19.6 - 26.5 N·m (2.0 - 2.7 kgf.m, 14.5 - 19.5 lb-ft) [Gasoline 1.6 MPI]
24.5 - 18.1 N·m (2.5 - 3.5 kgf.m, 34.3 - 25.3 lb-ft) [Gasoline 1.6 T-GDI]
11.8 - 14.7 N.m (1.2 - 1.5 kgf.m, 8.7 - 10.8 lb-ft) [Gasoline 2.0 MPI]
   
•
Install the all the components with the specified torques. If not, the clutch torque transaxle may have concerns or the mounting bolt can loosen.
•
When installing the clutch cover assembly, check the below fastening order for each number of bolts and tighten the bolts loosely. Then, fasten the bolts to their proper tightening torque. This can prevent twisting and vibration of the cover, and the lifting of the pressure plate.
