How is the clutch shown in the attached illustration engaged? See illustration GT-0032 Illustration GT-0032: the U.S. Coast Guard has not released this illustration.

Correct Answer: Option B — Clutch engages automatically when input shaft flange is rotating faster than the output assembly.

The SSS clutch is a self-synchronizing device that engages automatically when the input speed surpasses the output speed. As the input shaft accelerates, the helical splines force the clutch teeth into mesh, allowing for smooth, automatic power transfer without requiring external hydraulic or pneumatic control inputs for engagement.
