SAE Direct Drive PTO Clutches

Simple, Efficient, High-Torque Design

Logan PTO clutches are air or hydraulically actuated, and used in a variety of Industrial, On-Highway, Marine, Construction, Agriculture, Mining, Oil Field, and Rail applications – and are designed to mount between the power take-off of the engine and auxiliary attachment, i.e. single or multi-station pump drive.

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

Push Button Actuation – Eliminates Mechanical Linkages:

Self-adjusting piston travel compensates for any disc wear, eliminating the need for mechanical adjustment (i.e. levers, linkages, and yokes). The amount of hydraulic or pneumatic pressure applied, regulates the amount of torque transmitted through the clutch. Push-button, remote activation from inside a truck cab, engine control panel or hand-held device is now possible.

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

Mounting Options:

Ideal for in-line shaft or pump pad applications from an engine, or PTO pad. SAE or ISO mounting flanges. Available in A, B, C, C-C, D/E, E and F splines, plus bore and keyway configurations. Overhung Load Adapters (OHLA) are also available in common Dana or DIN style flanges. Integral torsional couplings available.

Standard Specifications: 
Standard Logan SAE PTO’s have input torque ranges from 159 lb. ft. (216Nm) to over 3,000 lb. ft. (4068 Nm).

Operating Speeds:  
Operating range from 1 to 3,000 RPM under load conditions.

Modified Standards: 
Higher horsepower, torque ranges, speeds, actuation pressures, and design configurations are available to meet customer's specific design requirements.
