Re: [TowerTalk] CDE Ham II

Thanks Bill and also Brad, W9FX, for the advice.

The lubricant is smooth and slippery, no grit or caking. I'll take that 
as a good sign and go with it.

73,

I bought a CDE Ham II rotor in 1976, used it for about five years and 
removed
it from service with the intent of getting my beams back in the air in 
short
order. I replaced a few parts in 1981 and lubricated the ball bearings. 
Turns
out that "in short order" turned into 23 years  :(

It was stored during that time in attics, barns and sheds. Dry but 
subject to
ambient outside temperatures (or greater when it was in the attic). I 
hooked
it up on the bench and it works. Removed the top casting to take a look at
the ball bearings. They are shiny and coated with the lubricant I put on 
them
23 years ago, a lubricant that I bought from CDE for just that purpose.

After all these years, is that lubricant on the ball bearings still a 
functioning
lubricant? Or is it of questionable character and should be replaced? If 
so, with what?

Thanks.

Steve
