My VP2 anemometer just started sticking in January after being in service for 9 months. Installed it in march 2016 (brand new VP2). Called Davis, the parts are about $60 shipped to Canada so I ordered what I needed, just the bearing/shaft assembly that bolts onto the bottom og the wind direction/anemometer arm. Appreciate the picture at the beginning of this thread regarding the Phillips head screw required to do the R+R.
Since my anemometer is at the top of a tower (wooded area, needs to be above tree height) knowing what screwdriver to bring along is exceedingly helpful. One question though; is there a nut on the top of the assembly that the screw tightens into, or does it just deadhead into the metallic mast? I am hoping I can just remove the wind cups, remove and install the new assembly, and re-install the wind-cup rotor without bringing the whole thing down to the ground, and while being careful in case there is a nut on top I could lose...!
I am really disappointed in this bearing/shaft design, in that: A) it failed so soon, and B) wasn't covered under warranty. The sales person at Davis I talked to reassured me that the replacement was an "update" to the original and it should last much longer... (I certainly hope so). My original VP weather station that is now partially retired and has the original wind speed/direction sensor on it, still works after 12-13 years of service, hence why I went with another Davis.
