Our TackTick T120 masthead wind indicator needs lubrication. I've opened up the unit but the anemometer shaft is held in place by a small round clip (see photo). I have been unable to figure out how to remove it so I can clean and oil the bearings. Can someone please advise?

I do not believe those locking washers are designed to be removed.

That said if you take a jewelers screw driver and pry 2 ot the 4 tabs up, it will slide off.

Gently bend the tabs down and reinstall and it will lock back.

I also think it is permanently lubricated and not designed for servicing. The bearings are likely worn and should be replaced. Not knowing what the lubricant is also presents a problem. Many things like this are dry with very smooth surfaces. Graphite or silicone spray would be my choice, but this may make things worse. I worked on WX equipment while in the USAF. The anemometer bearings were sealed roller and lightly lubricated or dry.

Those are called “push on retainers”. They are destroyed when removed. It is a quick inexpensive method of attachment on a shaft. You grab the unit with pliers. It collapses and pulled off.
If found replacements at our local Loews. Need the diameter of the shaft.

Usually made of a cheap metal. You may be able to find in stainless.
