The 747 is a rekeyable pin-tumbler padlock with a protected shackle made by American Lock. Among the largest of the American padlocks, the 747 comes in two types that change the method of disassembly. The 747 has remained relatively unchanged throughout the years with the exception of the company logo on the face of the padlock.

Disassembly instructions

The 747 comes in two types; One version has a sliding piece of metal on the bottom, the other has a screw-retained core retainer and small metal shield.

  • Unlock the padlock and free the shackle.
  • Unscrew the screw in the shackle toe hole.
  • Remove the core protector
  • Remove the core
  • Press down on the shackle to ease tension on the locking balls and tap lock on hard surface to remove the cam.
  • Remove the locking balls (they will be free once the cam is removed).
  • Remove the shackle retaining screw. This comes from the factory filled with a grey epoxy. Remove the epoxy then use an allen wrench to remove the screw.
  • Remove the shackle and shackle spring.
