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
