Abstract
A hydraulic actuating pin system is disclosed with an actuating pin, clutch drum, spring and hydraulics. The clutch drum has a scalloped annulus with raised and lowered sections. The spring pushes the pin towards the scalloped annulus. When the pin extends into the lowered section, it prevents the clutch drum from rotating. The hydraulics can compress the spring and extract the pin to allow the clutch drum to rotate. The proximal end of the pin can include a head, and hydraulic pressure can move the head to compress the spring. When the pin is fully extended into the lowered section, the end of the pin can not touch the bottom of the lowered section. The hydraulics can include a one-way valve allowing flow from a pump source to the pin, and a pressure release orifice allowing controlled release of hydraulic pressure from the pin.
