exchange Illustration 2: Wearing off of the blue layer Replacing the Sprockets when they have been damaged The sprockets always need to be replaced if they have been damaged through severe use or exterior influences. If you ride over a rock, or a tree trunk, for example, and you bottom out hard with the front sprocket, it might deform and would have to be replaced. Stones caught between belt and sprocket can cause damage to the teeth of the belt. Teeth might break off partially or completely. When this happens, the particular sprocket has to be replaced. Whether or not the belt has to be replaced would have to be determined with the criteria mentioned above (Replacing the belt after it has been damaged). Replacing belt and sprockets because of abrasion Both the belt and sprockets are parts that abrade or wear. Contrary to what you might expect, tests have shown that the belt tends to have a slightly longer life expectancy than the sprockets. You can check the abrasion of belt and sprockets with the Profile Wear Gauge as shown in illustrations 3 and 4. If the gauge result is equal to, or larger than 0.5mm, the particular belt or sprocket will need to be replaced. For a drive system in which all components have been used for the same amount of time it is recommended to replace all components, as soon as one of them needs to be replaced because of wear or abrasion. You can find further information about the use of your Profile Wear Gauge in the separate manual. 32

Replacing the Sprockets when they have been damaged<br />
The sprockets always need to be replaced if they have been damaged through severe use<br />
or exterior influences. If you ride over a rock, or a tree trunk, for example, and you bottom<br />
out hard with the front sprocket, it might deform and would have to be replaced. Stones<br />
caught between belt and sprocket can cause damage to the teeth of the belt. Teeth might<br />
break off partially or completely. When this happens, the particular sprocket has to be<br />
replaced. Whether or not the belt has to be replaced would have to be determined with<br />
the criteria mentioned above (Replacing the belt after it has been damaged).<br />
Replacing belt and sprockets because of abrasion<br />
Both the belt and sprockets are parts that abrade or wear. Contrary to what you might<br />

Wear Gauge as shown in illustrations 3 and 4. If the gauge result is equal to, or larger than<br />
0.5mm, the particular belt or sprocket will need to be replaced. For a drive system in which<br />
