Merci pour cette vidéo indispensable pour intervenir sur les roulettes du WAW. Attention sur la vidéo il manque une rondelle à droite de la roulette avant. Elle n'est pas facile à remettre en place...
Hi Elliot, you have WAW with mid-drive motor and on this type we started to mount a couple of years ago idlers with steel teeth. Thanks to the steel teeth the wear of the chain on teeth goes slower. It is possible that the double bearings will worn out faster than the steel teeth but I have not heard of that. If they do not turn easily any more and you have a lot of play then the bearings are bad and you should change. Most of the times the teeth wear out faster and then after that the chain will eat through the plastic. Then it is time to change. With Human powered WAWs or WAWs with a hub motor we mount idlers with plastic teeth as they are lighter and less noisy. With these idlers the bearings outlive the plastic.

Bonjour c’est à changer tous les combien ?
How can you tell when it's time to replace the idlers? An abnormal amount of lateral rotational play? Getting abnormally warm in use?
