Generation I - Over Shaft Actuation with Pilot Bearing
Logan Generation I Bell Housing PTO Series Description:
Air of Hydraulically actuated and designed to mount to a diesel or gasoline engine’s flywheel. The Logan Bell Housing PTO clutch is bored and key seated for shaft mounting. Torque is transferred from the disc pack to a geared drive ring which is attached to the engine’s flywheel.
The HPC is similar in design to the Logan CH Series clutch but can operate at higher actuation pressures, transfers more torque in a smaller envelope and is available in sizes up to 29” in. / 73.66 cm.
The HPC friction disc packs are suitable for either wet or dry operation. Actuation is accomplished through internal shaft and clutch passages.

Logan Bell Housing PTO’s - How They work:
Pressurizing the cylinder, forces the piston to clamp and lock the friction and steel separator discs. When pressure is removed, release springs separate the friction and steel separator discs, maintaining a running clearance when disengaged.
Where Used:
- Diesel or Gasoline Engine Powered Equipment
- Industrial Drives / Gensets
- Mobile Equipment
- Blowers, Vacuums, Fans
- Leaf and Debris Collection
- Tree and Brush Chippers
- Snow Removal Equipment
- Marine Propulsion and Auxiliary Gensets
Advantages:
- Air or Fluid Actuated for Remote, Sofstart® Activation
- Self-Adjusting Disc Pack
- Over shaft actuation – no rifle drilling of shaft required
- Pilot Bearing – Field retrofits within existing mechanical PTO’s
- Release springs in disc pack maintain running clearance during disengagement
- For in-line and side load applications
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 is now possible.
Over-Shaft Actuation:
Since the clutch is designed for over-shaft actuation, rifle and cross drilling the shaft is not required.
Standard Specifications:
Standard Logan Bell Housing PTO’s are available in SAE No. 7 to No. 00 Bells, with input torque ranges from 159 lb. ft. ( 216Nm) to over 7,473 lb. ft. (10133 Nm).
Operating speeds range from 1 to 3,000 RPM.
