Zusammenfassung:	A system for a wind turbine rotor blade, the system includes a pitch system that has a pitch bearing and a wind turbine hub, the bearing being attached to the hub and being attachable to a wind turbine rotor blade, and also including a pitch gear coupled to the pitch system. The pitch gear includes a first discrete segment and one or more other discrete segments, each segment having a plurality of teeth for engaging with and actuator such as a pinion. At least the first segment is held in place by releasable fasteners and extends along the pitch gear by a predetermined amount. The predetermined amount that the first segment extends along the pitch gear is determined based on anticipated wear of the pitch gear.
