	Remove/install
1	Remove power electronics		AR08.20-P-0011SRE
2	Unscrew nuts (2)	Bolt/nut, transmission to engine	*BA26.00-P-1002-01E
3	Remove both stud bolts of nuts (2) and screw in drifts	Bolt/nut, transmission to engine	*BA26.00-P-1002-01E
		Drift set	Fig 1
4	Remove screw/bolts (1)	Bolt/nut, transmission to engine	*BA26.00-P-1002-01E
5	Remove transmission (3) from electric motor (4)	Place transmission (3) carefully on electric motor (4). Otherwise the radial shaft sealing ring of the drive shaft of the transmission (3) can be damaged. Check for pilot bushings on electric motor (4).
6	Remove carrier (6) of the A/C compressor on electric motor (4)	If the electric motor (4) has been replaced.
7	Remove the bracket (7) from electric motor (4)	Engine 780.997 in model 453.091/391/491 except code 908 (On-board charger 22kW) If the electric motor (4) has been replaced. Bolt, bracket for charger for high-voltage battery to electric motor	*BA08.10-P-1004-01D
8	Remove air duct pipe (8) of electric fan	If the electric motor (4) has been replaced. Screw/bolt, air duct pipe to transmission housing	*BA26.00-P-1006-01E
9	Remove radial shaft sealing ring of drive shaft at transmission (3) with suitable tool	Replace radial shaft sealing ring. Do not grease sealing lip of the new radial shaft sealing ring. Drift set	Fig 1
10	Remove electrical wiring harness (9)	If the electric motor (4) has been replaced.
11	Remove rotor position sensor	If the electric motor (4) has been replaced.	AR08.10-P-0003SRE
12	Read off "Rr" and "0a" values of label (10) from new electric motor (4) and note	If the electric motor (4) has been replaced. Values on label (10) are required to align rotor position sensor, and are no longer legible after installation of new electric motor (4).
13	Install in the reverse order
14	Perform calibration of the rotor position sensor with diagnostic system	If the electric motor (4) has been replaced.	AD00.00-P-2000-06SR
