WUS MOTO Mounting process mode

Ref : C 307 020 0010

Version : E2

¨ The measurement of the residual torque is done by retightening the valve nut by a ¼ turn

maximum in reduced speed (1/4 of a turn in 10 seconds). Therefore use a torque-controlled tool

which is able to memorize the maximum torque. IF the torque mandatory to start the rotation of

the nut in the measurement is equal to 4 Nm, stop the procedure, the Torque is correct.

¨ The retightening torque may not be smaller than 4 Nm.

It is recommended to verify the screwing torque at each tire mounting.

6. TIRE MOUNTING

6.1. PRECAUTIONS

¨ Before any mounting operation of the tire, make sure that the Wheel Unit Sensor has been

correctly mounted and tightened to the rim.

¨ The tire must be lubricated so as to facilitate its mounting. Respect manufacturer

recommendations.

¨ NO lubrication product, tire ease or any other matter may partially or completely cover the

pressure measuring hole or the inflation hole of the wheel unit. In general, it is forbidden to

coat the wheel unit with a soap for tire mounting

¨ The tire must never be allowed to put mechanical constraints onto the wheel unit sensor during

the mounting operation; only a dynamic slide touch is acceptable, constant pressure stress is

forbidden.

¨ Make sure that the tire does not get trapped between the rim and the wheel unit sensor during

mounting procedure.

¨ It’s recommended to check the screwing torque before any tire mounting.

6.2. MOUNTING

¨ The bead of the tire must be engaged approximately 80° beyond the valve.

¨ Do not introduce a mounting tool between the valve and the point of engagement of the tire.

¨ Tire mounting must be done while moving away from the valve .

¨ Beyond this point starts the final engagement operation, which finishes in the zone of the valve.

¨ During this phase, only fast sliding touch is allowed during final tire jumping onto the rim. Process

to be validated by LDL Technology.
