How to replace a Davis 6410 wind speed sensor's cartridge with the bearings
Please follow the steps of this guide only, if your weather station has a Davis wind sensor. And the shaft of the wind cups are folded or broken, or its speed sensor is still sending speed data, but the reported values are lower than the real wind speed (In this case you can give it a try to clean the bearings, and lubricate them e.g. with WD40 before you would replace the whole cartridge).
This guide won't help if your wind direction sensor is malfunctioning.
Note: For this guide you will need to get a new replacement cartridge part (product no. Davis 7345.271). Which is available at our accessory shop, but you can probably buy it for cheaper from an other webshop or from a Davis distributor.
