[TowerTalk] thrust bearing lubrication

[Brahmangou at aol.com]

1. Remove the allen screw
2. remove the ball bearings one by one through the hole left by the  screw.
3. Now the bearing halves will come apart.
4. clean the races and ball bearings with brake  clean.
5. Apply grease to the races.
6. reassemble the halves.
7. reinsert the ball bearings.
8. Reinsert the allen screw.
have a beer, all done.
 
You have to disassemble it. The clunking is the dried out grease in  the 
races and has to be cleaned out.

Hi TTers,
I got that Rohn 45 tilt-over down and home  last week. In remarkably good 
condition. Only thing I wondering about is the  TB3 thrust bearing and how to 
lubricate it. It turns freely but has a notable  rumbling sound and feel to 
it. I notice at the bottom of the inside shaft area  where to mast passes 
through, is a recessed Allan head fitting/plug. Would  this be the place to 
remove and squirt in some white grease? And then replace  the plug? 
Thanks for your guidance,
Kathy
