Abstract
The invention relates to a method for performing up-tower maintenance on a gearbox bearing of a wind turbine. In particular, a method for performing up-tower maintenance on a gearbox of a wind turbine is disclosed. The gearbox has at least one bearing with an outer race and an inner race that rotates with respect to the outer race. The method includes forming a through-hole in a front cover of the gearbox, the front cover being stationary with respect to an axis of rotation of the bearing. The method also includes forming a recess in the outer race of the bearing. Further, the method includes inserting a connecting member through the through-hole and the recess so as to prevent movement of the outer race of the bearing with respect to a torque arm of the gearbox.
