Clutch Assembly: Inspection

  1. Check clutch disc for wear. Minimum wear limit of lining above rivet heads is .012" (.3 mm). Check disc runout by mounting disc onto input shaft. Mount dial indicator to transmission case with indicator plunger against face of disc.
  2. Measure runout at specified distance from hub center. See CLUTCH DISC MAXIMUM RUNOUT SPECIFICATIONS  . Measure backlash at outer edge of disc. See CLUTCH DISC MAXIMUM BACKLASH SPECIFICATIONS  . Replace clutch disc if runout or backlash exceed specification.
    CLUTCH DISC MAXIMUM RUNOUT SPECIFICATIONS

    Application Radius In. (mm) Runout In. (mm)
    Maxima 4.53 (115) .039 (.99)
    NX & Sentra

    Application In. (mm)
    Maxima .039 (.99)
    NX & Sentra
    1.6L .031 (.79)
    2.0L .035 (.89)
    Stanza .035 (.89)
  3. Check disc hub fit on input shaft splines. Disc should slide smoothly. Check end surface of pressure plate diaphragm springs for wear. Inspect thrust springs by shaking pressure plate assembly. Tap lightly on rivets. Replace assembly if noise is heard.
  4. Check diaphragm spring finger height differential. Adjust diaphragm fingers if height differential exceeds .020" (.51 mm) on Maxima or .028" (.71 mm) on NX, Sentra and Stanza.
  5. Inspect flywheel and pressure plate for scoring, grooves and warpage. Light roughness on pressure plate and flywheel may be dressed using fine emery cloth. Machine flywheel surface if necessary. If surfaces are deeply scored, replace flywheel or pressure plate.
