To ensure ease of removing and installing a Turret, here is a short reminder. The Turret turns as the press Ram is lowered. This is due to the Square Ratchet riding on the Index Rod. The Square Ratchet is designed to last nearly indefinitely and resides in the nylon housing (Auto Index Clamp). In order to maintain the integrity of the Square Ratchet, remember to raise the Ram which disengages the Ratchet from the housing and allows the Index Rod to spin freely. It is at this point that the Turret can be removed and installed at will.
