[Milsurplus] BC-342 Oil-Filled Caps

[Raymond Cote]

Usually the bottom of the can is folded over to lay flat on the sides. My experience is that most are 1/8 up to 1/4 inch overlap. I start at one end, Heat the hell out of a small section, suck it or wick it and then while hot insert a small jewelers screwdriver or similar small flat item under the fold and pry it away from the base metal.  The hotter it is, the more of the lip will pry away without having to remove lots and lots of solder.  It is a learning process,and as usual, wear all necessary protective gear and be careful of the oil.  Older caps have PCBs but if you don't drink it, it usually will not hurt you.  I then dump the oil into a stand by can and the heating and solder removal is much easier.
