6.1	Mark the front side of the washer (2)	Vehicles with automatic transmission Installation: The washer (2) must be installed back into the same position as bulging caused by the bolts can generate an incorrect torque.
7	Unscrew bolts (1a) on two-mass flywheel (1) or clutch plate	Installation: If an angle tightener is not available, the bolts can be tightened further by the specified angle in a single operation using a socket wrench and breaker bar. To avoid any angle errors, a bending rod torque wrench must not be used for tightening according to angle degrees. This falsifies the tightening torque. Engine 271:
		Bolt for flywheel or two-mass flywheel / driven plate to crankshaft Engine 272:	*BA03.30-P-1003-01I
		Bolt of starter ring gear/ drive plate to crankshaft	*BA03.30-P-1002-01M
		Bolt, two-mass flywheel to crankshaft	*BA03.30-P-1003-01M
8.1	Remove washer (2)	Vehicles with automatic transmission
