Fairly self-explanatory really!

I need to get my old style ST60 wind transducer down to replace the bearings. I don't want to get up there and find I've not got the right tools, so what am I likely to need aloft?

Thanks!
 
If it's like mine it should just unscrew. On mine there is a small black plastic box which has 3 screw holes to fix the plastic box to the mast. The transducer arm has a built in DIN plug (male) which plugs into the black plastic box and is retained by a knobbly plastic screw thingy. The plastic box fastening should not need touching, just unscrewing the knobbly plastic screw thingy will allow the plastic knobbly to pull clear of the plastic box (sliding along the transducer shaft) thereby allowing the male side of the DIN plug to pull out. The plastic knobby thing might be tight - a pair of pliers would not have wide enough jaws to grasp the knobbly thing - one of those adjustable sort of plumbing wrenches would do.
 
Brilliant, thanks all.

One other question, I hear the the cups and vane are fragile and may break. How likely is this in people's experience? Trying to balance up spending £40 on new ones "just in a case"...
 
I have had to replace because of a broken vane. As stated, there is just a collar to unscrew. It might be worth taking something to grip the collar with, such as a rubber strap spanner or bit of sticky mat.
 
For mine, I've made up a cover from a bit of rubber tube to protect the electrical contacts from the elements when the transducer is removed. Sorry, I can't give you the necessary diameter, about 20mm at a guess, perhaps a bit bigger?? A wrapping of PVC tape will probably be as good.

They can become a little brittle with exposure over the years but it should withstand reasonable handling, take a bag up with you on a line pop it into the bag and lower it onto the deck. They used to come with a protective cap for the masthead unit once the arm is removed but a bit of insulating tape and a small poly bag will protect it from water ingress.
 
Must be that time of the year. Did mine a couple of days ago. As above, just unscrew from mast and drop down in bucket. Seconds to do (once up at the top - luckily my son did all the hard work...)
