Before Tacktick was Raymarine, I purchased a windset with Seamark Nunn, and the wind transmitter gave up sending data within a year. No problem, Seamark Nunn contacted Tacktick and they replaced the windunit at no costs with a brandnew mast unit. I love that ! topservice, and in the box with the new unit there was a apology note from Tacktick as well. I hope Raymarien can meet that level of service... ;-)
This year, after using the instruments for 5 years with a lot of pleasure in having this instruments aboard, the mast unit stopped turning at low windspeeds. With a little research
I found this topic about "bearing issues" and I decided to take the unit apart to inspect it. wearing ? I dont believe that !
I found out the spindle and bearings are made of inox, and stil there seems to be some rusty (?) debree of wearing in the cup and on the lower bearing itself. RUST ??
That cannot be the thruth...
I rinsed te lower bearing to clean it from the brown debree, cleaned the cup, flushed the lower bearing with a good clear oily lubricant to get lost
of the K3, cleaned it and lubricated the lot with silicon spray.
the unit is rotating as if it was new.
I do not know how long it will stand out this way, but I assume the bottom opening in the bearing cup is the weakest spot of the wind-unit.
I know there are spiders and all kind of other insects investigating any hole in my ship, so I am not that supprised the unit has become disfunctional by this cause.
it did a lot of good, it would not if it was wearing indeed.
so maybe: take it apart every one or to years and clean it :-)
I am very fond of my tacktick's as I found out (with NMEA-unit GPS
connected) a lot about the very strange sailingcharacteristics of my classic, over 100 y.o. unpredictable "lady" of a yaght
I now know how to race
this old lady :-) and I can tell you: it;s different from every manual :-)
