Raymarine ST60 wind transducer repair?

[dunedin]

I have two Raymarine wind transducers with different faults. One was replaced after just 3 years with some form of electronic fault, but is in perfect condition mechanically.
Now the replacement has a failed bearing on the wind speed sensor, that is making it stick.
It would be good to be able to use these to create a single working system.

It is easy to remove the vane and spinner. And it is easy to remove the top bearing and sensor - but that is fine on both.

What I am struggling to do is to find a way to replace the bottom bearing - or shift the electronics chip onto the good bottom bearing.
I see that the electronics chip is sold as a spare part. But can’t find any instructions for how to remove it without breaking things.

Anybody done this? Thanks

Hello

 

[dunedin]

Brilliant thanks Klausen. Will have a go and see what I can do.
Thanks

You are welcome! If there are any parts leftover when switching, before you throw them in the bin, send them to me. Greetings, Klaus

Klausen. Was that PDF you linked to from you, or something useful you located elsewhere?

I was easily able to lift off the circuit board, knowing from the notes it was a simple lift using the holes, and not otherwise secured in place. I haven't disconnected the wires yet.

However, I seem to have reached the same point as your notes did. I hadn't realised that the bearings need to be pulled outwards (had thought push inwards, so your notes saved me damaging things). But seem like force would be needed to remove the disk sensor to enable pushing out the bearing. This might not end well?

So perhaps Plan B, I might try moving the working chip board to the mechanically sound older vane with unknown fault,

So how does one get the wires off without damaging the chip board - do all the white bits come off or do some stay with the board ? I assume it is a push fit, not soldered? Thanks

You can disconnect the circuit board, there is a plug. Be careful when you remove the " disc". Warm it up a little bit and then grab the middle part with pliers.

Great thanks - circuit board disconnected. I see that the majority of the white plastic bit remains attached to the circuit board, just prise the very thin bit of white at bottom.
Now intend to rebuild based upon arm with intact lower bearings and circuit board and top bearing from one just taken off.

Is there any way to easily test before being refitted 20m up the mast?

I believe there is a YT Video about testing
