
Do not position on the tire side wall, but on the bead flank only.
The carcass can otherwise be damaged.

6

Pry off tire on inside and outside over safety bead seat of disk wheel.


Model 636, 639, 906
with code RY2 (Tyre pressure monitoring system)
Do not exert any force on the tire pressure sensor (1).
Otherwise it will be damaged.

 Model 636, 639, 906
with code RY2 (Tyre pressure monitoring system)
When prying off tire bead, start on outside of disk wheel opposite tire pressure sensor (1).

7

Clamp disk wheel on tire mounting device.

8

Coat rim flange and tire beads with commercially-available tire mounting paste.

9

Align assembly head at a small distance (X) and distance (Y) to the disc wheel.

10

Position disk wheel at mounting head of tire mounting device.


Model 636, 639, 906
with code RY2 (Tyre pressure monitoring system)
Do not exert any force on the tire pressure sensor (1).
Otherwise it will be damaged.

 Position the disk wheel in the direction of rotation such that the valve (43g) is approx. 10 cm in front of the mounting head.

11

Detach tire.

 To do so, pry the tire bead over the assembly lug using an assembly lever.

12

Remove valve (43g).

Model 636, 639, 906
except code RY2 (Tyre pressure monitoring system)



Check

13

Check condition of disk wheel.

AR40.10-P-1010-01A

14

Check tire pressure sensor (1), union nut (2), valve body (3), screw (3a) and shoulder seal (3s) in installed condition.

Model 636, 639, 906
with code RY2 (Tyre pressure monitoring system)


Do not remove tire pressure sensor (1). Do not retighten screw (3a) and union nut (2).
Otherwise, the tire pressure sensor (1) will be damaged.

If tire pressure sensor (1), valve body (3), shoulder seal (3s) are damaged, or if union nut (2) or screw (3a) are loose:



Replace tire pressure sensor (1).

Install

15

Install new valve (43g).

Model 636, 639, 906
except code RY2 (Tyre pressure monitoring system)

 Install a new valve (43g) without valve element.

16

Coat rim flange and tire beads with commercially-available tire mounting paste.

17

Align assembly head at a small distance (X) and distance (Y) to the disc wheel.

18

Place new tire at angle onto disk wheel, and pull on over the rim flange using tire mounting device.


Model 636, 639, 906
with code RY2 (Tyre pressure monitoring system)
Do not exert any force on the tire pressure sensor (1).
Otherwise it will be damaged.

 Observe the running direction on tires with specified running direction. Put as little stress as possible on bead area.

19

Align light spots of tire and disk wheel with each other.

20

Remove disk wheel with tire from tire mounting device.

21

Inflate tire.

 Inflate tire without valve element to a maximum of 3 bar. The tire must slide evenly over the safety bead seat of the disk wheel.

If necessary,



Coat the tire beads again with commercially available tire mounting paste.

22.1
