Tool retention system having cam-driven keys

A retention system for use in connecting a replaceable tool to a work implement, the retention system comprising:

• a generally cylindrical sleeve configured to be received within corresponding bores in the work implement and the replaceable tool, the generally cylindrical sleeve having radially oriented holes passing through an outer surface thereof at opposing ends and an anti-rotation feature inhibiting rotation of the generally cylindrical sleeve;
• a pin disposed within the generally cylindrical sleeve and having first and second cam lobes located at opposing ends adjacent the radially oriented holes of the generally cylindrical sleeve and radially offset from a central axis;
• first and second keys disposed within the radially oriented holes of the generally cylindrical sleeve and configured to ride on the first and second cam lobes, the first and second keys being simultaneously movable during rotation of the pin from a retracted position to an activated position at which the first and keys engages the replaceable tool;
• first and second seals disposed around the first and second keys and configured to engage the generally cylindrical sleeve;
• and
• a cap configured to close off an open end of the generally cylindrical sleeve and selectively inhibit rotation of the pin.

A method of securing a replaceable tool to a work implement, the method comprising:

• moving the replaceable tool over a portion of the work implement to generally align corresponding bores in the replaceable tool and the work implement;
• placing a sleeve of a retention system into the corresponding bores;
• and
• rotating a pin within the sleeve to cause a cam lobe to push a key radially outward through a hole in the sleeve and engage the replaceable tool.
