
Do not position bead breaker shovel on tire sidewall.
The carcass can be damaged otherwise.


Do not position bead breaker shovel on the inner or outer side of the tire in the area of the valve body (3) or opposite the valve.
The tire pressure sensor (A69/1, A69/2, A69/3, A69/4) may be damaged otherwise.

7

Press the inner and outer bead flank over the safety bead seats into drop center of disk wheel.

8

Fasten disk wheel on tire mounting device.

9

Apply coating of assembly paste to shoulder of disk wheel and to tire beads.


Do not apply assembly paste to the tire pressure sensor (A69/1, A69/2, A69/3, A69/4).
Otherwise, the tire pressure sensor (A69/1, A69/2, A69/3, A69/4) may malfunction.

10

Position disk wheel on tire mounting device such that the valve, as seen in direction of rotation of the disk wheel, is located 10 cm behind the mounting head.

11

Align mounting head at small distances (X, Y) to disk wheel.

12.1

Use assembly lever to lever tire beads over mounting lug of mounting head and detach tire from disk wheel.

For tires without emergency running characteristics.


Do not exert any force on the tire pressure sensor (A69/1, A69/2, A69/3, A69/4).
Otherwise it will be damaged.

12.2

Position hold-down tool on upper side of bead flank and push tire into the drop center, then position hold-down tool on underside and detach tire.

For run-flat tires.


Do not exert any force on the tire pressure sensor (A69/1, A69/2, A69/3, A69/4).
Otherwise it will be damaged.

13

Clean tire pressure sensor (A69/1, A69/2, A69/3, A69/4) using a clean, lint-free cloth.


Do not use compressed air; use a solvent or cleaner.
Otherwise damage can occur to the tire pressure sensor (A69/1, A69/2, A69/3, A69/4).

 The tire pressure sensor (A69/1, A69/2, A69/3, A69/4) can also be reused after the TIREFIT tire repair kit has been used.

If there is residue remaining on the diaphragm opening after cleaning.



Replace tire pressure sensor (A69/1, A69/2, A69/3, A69/4).

Check

14

Check condition of disk wheel.

AR40.10-P-1010-01A

15

Check tire pressure sensors (A69/1, A69/2, A69/3, A69/4) and valve bodies (3) in installed condition for damage.


Do not retighten valve nut (2).
Otherwise, the tire pressure sensors (A69/1, A69/2, A69/3, A69/4) will be damaged.


Only use plastic valve caps.
Otherwise corrosion damage may occur.

If the valve nut (2) or the tire pressure sensors (A69/1, A69/2, A69/3, A69/4) are loose or the tire pressure sensors (A69/1, A69/2, A69/3, A69/4) are damaged.



Replace tire pressure sensors (A69/1, A69/2, A69/3, A69/4).

Attach

16

Replace valve.

 Use valves with valve elements made from nickel-plated brass only.

17

Apply assembly paste to shoulders of disk wheel and tire beads of new tire.


Do not grease the tire pressure sensor (A69/1, A69/2, A69/3, A69/4).
Otherwise it can lead the tire pressure sensor (A69/1, A69/2, A69/3, A69/4) to malfunction.
