Warning

Warning

Be careful not to be bent or twist bolts. Loosen bolts in diagonal directions.

Inspection

  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.)

Installation

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.
  1. 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.

  1. The 'T/M SIDE' marked surface should face the transaxle.

  1. Install the clutch disc and the cover with SST (09411-1P000, 09411-G2100).

  1. Install the clutch cover bolts.

Warning

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.
  1. Install the hybrid motor assembly.

    (Refer to Hybrid Motor System - "Hybrid Motor Assembly")
