Support clutch pressure plate and clutch disc with mandrel & remove it. NOTE: 1. It is recommended to replace a defective disc having any of the above mentioned defects with a new genuine clutch disc. We do not recommend removal and replacing of clutch facing. 2. We do not recommend overhauling of the clutch pressure plate assembly. However, before re- fitment, the assembly should be checked for specifications and should conform to the data of clutch pressure plate assembly given on page 3. 3. Use correct clutch discs for the 1.2L NG NA versions Identification. 4. Use Disc and Pressure plate of the same make. Ensure that the clutch facing material is not contaminated with oil or grease as this shall result in clutch slipping. INSTALLATION : Carryout the clutch removal steps in appropriate sequence for its fitment. However, following care must be taken during installation. Clean friction face of flywheel and check for cracks, scoring, burn marks or unevenness. If necessary, machine flywheel friction face just to clear the defect. Lightly apply Dow corning P40 grease on the disc splines. Install disc and pressure plate assembly. Press the aligning mandrel through the pressure plate assembly and clutch disc and centralize clutch disc on flywheel by locating the mandrel at the flywheel end. NOTE: Do not mix clutch mounting bolts with other fasteners. Do not use longer or shorter screws. Longer screws may not tighten the clutch at all. Shorter screws will not provide enough threads to achieve desired tightening. While tightening the clutch mounting screws check aligning mandrel for continuous free sliding to ensure concentric installation of clutch disc which will avoid trouble during the installation of the transaxle. 11.
