YST Corp square taper bottom bracket cartridge disassembly

I disassembled a YST Corp bottom bracket that came out of a 1990s mongoose Alta mountain bike. I don't know if this BB cartridge is original or not but I was attempting to pack the bearings with grease. After feeling the bearings were worn I just ordered a new one. The specs to this one are:
YST Corp
BB 965G
BC 1.37X24
L 68 R
The length of the spindle is 110mm.
