Bell Housing Power Take-Off Clutches

Logan Air / Fluid actuated Bell Housing PTO clutches are self- adjusting and designed to mount directly to a diesel or gasoline engine’s flywheel.

The friction disc packs optimize dry operation and actuation is accomplished through a stationary cylinder-piston arrangement or through internal shaft and clutch passages.

The clutch is bored and keyseated for shaft mounting. Torque is then transferred from the disc pack to a geared drive ring that is attached to the engine’s flywheel.
