[TowerTalk] Bearings in Rotators

[AA6DX - Mark]

Hello TTers ... just musing ... all the CDE / Hy-Gain rotators I have taken 
apart for the first time had room for a lot more ball bearings than came 
with "stock".  Years back, I went to the Bearings store locally and stocked 
up, and every time I put a rotator back together, I filled the race, within 
the plastic holder.
What is the consensus on this practice .. why would you NOT do that .. and, 
of course, why does NOT the manufacturer ... it seems like such a 
no-brainer, but there must be a reason, other than $$$   ????    73, Mark
