My impression is that wind turbines require periodic maintenance - after all there are few harsher environments for an electromechanical device than 24/7 exposure to the British climate.

The pictures of the Navitron kits show the main generator unit and housing already assembled and no obvious means of disassembly for periodic maintenance.

So what maintenance is really necessary on Navitron turbines and at what schedules ? (I know the FAQ says they are robust and do not really need attention but things must wear out!)
What are the normal things that go wrong and are spares easily available ? (Again the FAQ says spares are available but are bearings, thrust washers, slip rings, etc really available from stock?)

Believe it or not, 99% of the requests we get for spares are for situations where the towers have fallen over due to undersized concrete foundations for the guypegs or ropes snapping during initial raising of the tower.

Therefore we have supplied mainly replacement nose cones and blades for such mishaps. I would suggest that balancing the blades prior to use is the most important thing, and this should be checked at regular intervals. You will need to also check mechanical stability of the tower, guylines and anchor points etc once a year for safety.

I have a selection of bearings etc in stock, which I bought with the first order, but I have never needed to supply any. The bearings tend to be quite over-sized for the job, hence fairly reliable.
