2	Remove crankshaft position sensor		AR15.12-P-2133CD
3.1	Remove screw/bolts (1) on flywheel	ENGINE 651 in MODEL 166, 172, 204, 207, 212 (except 212.098/298), 218, 221 with CODE 411 (6-speed manual transmission) The crankshaft must be counterheld with a suitable tool to avoid it also turning.

3.2	Report screw/bolts (1) on drive plate	ENGINE 651 up to 7/14/11 in MODEL 166, 172, 204, 207, 212 (except 212.098/298), 218, 221 with CODE 423 (Automatic five-speed transmission (NAG)) ENGINE 651 up to 7/14/11 in MODEL 166, 172, 204, 207, 212 (except 212.098/298), 218, 221 with CODE 427 (7-speed automatic transmission) Replace screw/bolts (1) and perforated disc. Both screw/bolt (1) next to the cylinder pin should be used with the 15.5 mm thick bolt head, for the remaining 6 screw/bolts the screw/bolts (1) must be used with a 21.2 mm thick bolt head. For fundamental use of the screw/bolts (1) with the 21.2 mm thick bolt head there is the danger that the bolt head touches the cylinder pin and this can cause strain cracks on the Flex plate. The crankshaft must be counterheld with a suitable tool to avoid it also turning. ENGINE 651 up to 7/14/11 in MODEL 166, 172, 204, 207, 212 (except 212.098/298), 218, 221 with CODE 423 (Automatic five-speed transmission (NAG)) with CODE B03 (ECO start/stop function) ENGINE 651 up to 7/14/11 in MODEL 166, 172, 204, 207, 212 (except 212.098/298), 218, 221 with CODE 427 (7-speed automatic transmission) with CODE B03 (ECO start/stop function) For these vehicles the crankshaft must be held with a counterholder .

3.3	Remove screw/bolts (1) on drive plate	ENGINE 651 as of 7/14/11 in MODEL 166, 172, 204, 207, 212 (except 212.098/298), 218, 221 with CODE 423 (Automatic five-speed transmission (NAG)) ENGINE 651 as of 7/14/11 in MODEL 166, 172, 204, 207, 212 (except 212.098/298), 218, 221 with CODE 427 (7-speed automatic transmission) Use screw/bolts (1) with a 21.2 mm thick bolt head. For use of the screw/bolts (1) with the 15.5 mm thick bolt head strain cracks can occur on the Flex plate. Replace screw/bolts (1) and perforated disc. The crankshaft must be counterheld with a suitable tool to avoid it also turning. ENGINE 651 as of 7/14/11 in MODEL 166, 172, 204, 207, 212 (except 212.098/298), 218, 221 with CODE 423 (Automatic five-speed transmission (NAG)) with CODE B03 (ECO start/stop function) ENGINE 651 as of 7/14/11 in MODEL 166, 172, 204, 207, 212 (except 212.098/298), 218, 221 with CODE 427 (7-speed automatic transmission) with CODE B03 (ECO start/stop function) For these vehicles the crankshaft must be held with a counterholder .
