INSTALLATION AND USE
Follow the supplied disc-orientation diagram for this exact friction-disc design. Follow the fitting and bedding-in instructions. Ceramic friction material can engage more abruptly than an original organic disc. A single-mass flywheel can transmit more engine harmonics and gearbox rollover noise, particularly at idle or when the engine labours. TSB-SMF02 explains this characteristic. Confirm release travel and clearance before operating the clutch.
