[SADXA] Grease gun?

I'm having troubles rotating the antenna on my old tower and have 
isolated the problem to the tower's thrust bearing.  It's taking too 
much effort to rotate, and my rotor software is going into a "safety 
stop" mode.

In looking at the setup I realize that it's been about 25 years since 
that thrust bearing was lubricated.  It feels like the grease around the 
ball bearings has dried up over the years and that's causing a lot of 
extra friction.

Lubricating the thrust bearing should be easy to do.  The bearing takes 
a standard automotive Zerk fitting, and it's sitting at about knee 
height on the bottom of the tower.  It should be an easy job except that 
I gave away my grease gun years ago, when my wife and I were lightening 
the load to prepare for the cross-country move back to Tucson.

Does anybody have a grease gun that I can borrow to fix my problem?

Thanks,   Jim  W9FI
