INSTALLATION AND USE
The supplied TSB-174 requires the sprung disc spring cage to face the flywheel; check the supplied diagram before assembly. Follow the fitting and bedding-in instructions. 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.
