  • Since the sports clutch is a product with a purpose to transfer the power, it may also transfer the sound generated in the drive train.
  • When replacing the clutch, replace the clutch discs and the clutch cover as a set
    (EXEDY Clutch Set is recommended).

Clutch disc
  • Confirm that it will move smoothly by sliding it into a main drive shaft before the installation. This preliminary check will confirm that you have a correct product or not.
  • Apply a small amount of grease on the spline, slide it into the main drive shaft again, and wipe off any grease that has strayed. Excess grease will cause slipping or judder.
  • Never use the clutch disc that you have dropped. Also, do not handle with hands contaminated with oil, etc. This will cause bad disengagement or judder.
  • When mounting the transmission, align the height, tilt, and tooth surface, and slide the main drive shaft smoothly without any excess force. Forceful insertion will cause denting on the gear tooth surfaces, deformation of disc, etc., causing bad disengagement.

Clutch cover
  • Wipe the pressure plate surface (center plate surface for twin or triple) and flywheel surface of the clutch cover with a clean cloth. It will cause bad disengagement or judder if there is any oil attached.
  • When mounting the clutch cover to the flywheel, do not tighten the bolts at once, but tighten them in increments diagonally. The lever of the diaphragm spring will be uneven if the bolts are tightened at once, causing bad disengagement or judder.
