Cressi AC 2 disassembly & reassembly

Cressi AC2 first stage disassembly and reassembly without any “special” tools (except third hand).
Cressi first stage repair, service, maintenance.
I tried to make sure everything was seen on camera. Didn’t use any of the “special” tools including a torque wrench.
Did not replace any orings or anything as this will just be used for spare parts or a tire inflator.
