		Model 204	AP40.10-P-4050CW
		Model 209	AP40.10-P-4050Z
2.1	Detach jammed balance weight (43a) with assembly tool		*124589176300
2.2	Remove bonded balance weight (43a) with removal tool	Do not use a hard, pointed or sharp-edged tool, in order to avoid damaging the surface of the disk wheels.	*129589005900
		Loctite 7200	*BR00.45-Z-1038-04A
3	Remove valve element from valve (43g)
4	Draining TIREFIT sealant out of tires	After using TIREFIT tire sealant
		Model 204	AR40.10-P-1080CW
		Model 171, 209	AR40.10-P-1080A
5	Position the press-off blade of the tire mounting device on the tire bead flank	Do not position press-off blade on the tire flank otherwise the carcass will be damaged. On vehicles with code (470) Tire pressure monitoring system, do not position the bead breaker shovel on the inside or outside of the tire in the area of the valve (43g), otherwise the tire pressure sensor (A69/1 to A69/4) will be damaged. Position the blade on the bead flank opposite the valve (43g).
		Tire mounting device gotis://F_40.1_01.0
6	Press inner and outer bead flank over safety bead seats and into drop center of disk wheel
7	Fasten disk wheel on tire mounting device
8	Apply mounting paste to disk wheel flange and tire beads	Wide-tire mounting paste	*BR00.45-Z-1066-06A
9	Position disk wheel on the tire mounting device	Position the disk wheel so that the valve (43g) is 10 cm behind the assembly head, viewed in the direction of rotation (arrow) of the disk wheel.
10	Align mounting head at small distances (X, Y) to disk wheel
11	Use assembly lever to lever the tire beads over the mounting lug of the mounting head and detach the tire from the disk wheel	On vehicles with code (470) Tire pressure monitoring system, no forces should act on the tire pressure sensor (A69/1 to A69/4), otherwise it will be damaged.
	Checking
12	Check condition of disk wheel		AR40.10-P-1010-01A
13.1	Check tire pressure sensor (A69/1 to A69/4) and valve body (3) in the installed condition for damage	Vehicles with code (470) Tire pressure monitoring system
		Do not remove tire pressure sensor (A69/1 to A69/4). Do not retighten union nut (2), otherwise the tire pressure sensor (A69/1 to A69/4) will be damaged.
		Replace all components, if the union nut (2) or tire pressure sensor (A69/1 to A69/4) are visibly loose or damage can be detected:
		Replace tire pressure sensor (A69/1 to A69/4).	I AR40.15-P-0080CW
13.2	Install new valve (43g).	Vehicles without tire pressure monitoring system
	Clean
14	Clean tire pressure sensor (A69/1 up to A69/4)	Vehicles with code (470) Tire pressure monitoring system Wipe off dirt with a clean, lint-free cloth only. Do not use any compressed air, solvents or cleaners otherwise the tire pressure sensor (A69/1 to A69/4) will be damaged.
	Attaching
15	Apply mounting paste to disk wheel flanges and tire beads of new tire	Wide-tire mounting paste	*BR00.45-Z-1066-06A
16	Position disk wheel on the tire mounting device	Position the disk wheel so that the valve (43g) is approximately 180° opposite the mounting head. Tire mounting device gotis://F_40.1_01.0
17	Place new tire at an angle on disk wheel and align mounting head at small distances (X, Y) to disk wheel	Observe running direction on unidirectional tires. Observe the markings indicating the inside and outside of the tire. On vehicles with mixed tires observe the correct assignment of the tire to disk wheel.
18	Pull tire over shoulder onto disk wheel with tire mounting device	Vehicles with code (470) Tire pressure monitoring system: No forces should act on the tire pressure sensor (A69/1 to A69/4), otherwise it will be damaged. Load the tire beads as little as possible.
19	Align the match points of the tire and disk wheel relative to one another
20	Remove disc wheel with tire from tire mounting device
21	Remove valve element from valve (43g)
22	Inflate tires	Inflation pressure max. 3 bar. The tire beads must slide evenly over the safety bead seats of the disk wheel; if this is not the case, apply mounting paste to the tire beads again.
		Wide-tire mounting paste	*BR00.45-Z-1066-06A
23	Turn valve element into valve (43g)
24	Adjust tire inflation pressure to correct pressure.	See tire pressure label in the vehicle's fuel filler flap.
25	Balance wheel	Model 204	AR40.10-P-1040CW
		Model 171, 209	AR40.10-P-1040A
26	Mount wheel
