4 Disassembly / Reassembly Flywheel Danger - Attention During dismounting be particularly careful not to let the flywheel fall, as this can be very dangerous for the operator. Use protective goggles while removing the starter ring gear. 11 Unscrew the screws that fasten it to the crankshaft. In order to replace the ring gear, it is necessary to disassemble the flywheel. Cut the ring gear in several places using a chisel and remove it. Heat the new ring gear uniformly and keep it at a temperature of 300°C for 15÷20 minutes. Insert the ring gear into its seat and place it carefully on the rim of the flywheel. eave to the ring gear to cool gently before reassembling the flywheel. When refitting tighten the screws at 80 Nm. Driving pulley Important To loosen or screw in screw 1 at the set torque you must always stop the crankshaft and not other parts of the engine. Lock the crankshaft. Remove the pulley, after having unscrewed central screw 1 and proceed with the four lateral screws. The central bolt 1 is left-handed. When reassembling, apply some Moly-slip antiseizure compound on the screw thread and tighten at 360 Nm. 12 Note: When pulley reference mark A aligns with the timing cover reference mark B, the flywheel side piston is at TDC. - 26 - FOCS Workshop Manual_cod. 1.5302.858_1° ed_ rev. 00
Disassembly / Reassembly 4 Timing belt cover Loosen the five screws and remove the cover. When rifitting tighten the screws at a torque of 10 Nm.
