3	Remove tire pressure sensor (7) with valve stem (4)
4	Unscrew valve protection cap (1)	When reusing the tire pressure sensor (7).
5	Remove sealing ring (5)	When reusing the tire pressure sensor (7).
6	Remove valve seat (6)	When reusing the tire pressure sensor (7).
7	Detach valve stem (4) from tire pressure sensor (7)	When reusing the tire pressure sensor (7).
	Clean
8	Clean tire pressure sensor (7)	When reusing the tire pressure sensor (7).
		 Only remove dirt with a clean, lint-free cloth. Do not use solvent, cleaner and compressed air. Otherwise malfunctions or damage may occur.
		 The tire pressure sensor (7) can no longer be used after applying the TIREFIT tire sealant.
9	Clean the disk wheel in the area of the valve bore
	Install
10	Insert new valve stem (4) in tire pressure sensor (7)	When reusing the tire pressure sensor (7).
		 Ensure correct positioning of valve stem (4).
11	Install valve seat (6)	When reusing the tire pressure sensor (7).
		 Markings (arrows) on valve seat (6) and tire pressure sensor (7) must be opposite one other.
12	Install sealing ring (5), as shown	When reusing the tire pressure sensor (7).
		 Pay attention to installation position.
13	Screw valve element (3) into valve stem (4)	When reusing the tire pressure sensor (7).
		 Valve element in valve stem	*BA40.15-N-1002-02TS
14	Screw on valve protection cap (1)	When reusing the tire pressure sensor (7).
15	Insert valve stem (4) into valve hole
16	Hold tire pressure sensor (7) and screw respective new union nut (2a, 2b) onto valve stem (4)
Topical note	Notes on self-locking nuts and bolts		AH00.00-N-0001-01A
		 Do not counterhold valve stem (4) when tightening the respective union nut (2a, 2b) in any case. Otherwise the valve stem (4) is not screwed on correctly and the tire pressure sensor (7) will get damaged when driving.
		 Union nut to valve body for tire pressure sensor	*BA40.15-N-1001-02TS
17	Mount tire		AR40.10-D-1030TS
		 The lever arm of the tire mounting device must lie 180° away from the tire pressure sensor (7). Otherwise, the tire pressure sensor (7) will be damaged.
