[Towertalk] Disassembling A4 elements

[Chuck Counselman]

The best product I know for getting stuck things unstuck is called 
(appropriately) BreakFree CLP.  I find it most often in gun stores.

It wicks into cracks very well, and displaces water as WD-40 does, 
but it is about as viscous as SAE 30 motor oil.  It also contains 
microscopic particles of Teflon (PTFE).  Unlike WD-40, it lubricates 
well and lasts a long time.  In motor and pump bearings it lasts much 
longer than ordinary oil.  Using this stuff I have gotten years more 
service out of several motors whose bearings seemed shot beyond hope, 
and that ordinary oil would not free up.
