Replacement Parts

The 13894 bearings are located in the propeller housing. The bearings can be replaced by mechanically-adept users—especially if they are familiar with replacing bearings in other mechanical systems. Otherwise, replacement at the factory is recommended (requires an RMA).
The 13895 bearings allow the wind vane to turn about the axis of the mounting shaft. These bearings are located within the shaft assembly and replacement at the factory is strongly recommended; please request an RMA.
The 3659 is an unthreaded pipe used to mount the sensor to a crossarm. The pipe is easily replaced by the user.
