Generation II - Through Shaft Actuation Without Pilot Bearing

Logan Generation II Bell Housing PTO Series Description:

Air of Hydraulically actuated and designed to mount to a diesel or gasoline engine’s flywheel. The 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. Gen. II clutches do not require a pilot bearing.

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 PTOs
  • Release springs in disc pack to maintain running clearance during disengagement
  • For in-line and side-load applications

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.

 

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.

 

Through-Shaft Actuation:

Since the clutch is designed for through shaft actuation, the shaft must be rifle and cross-drilled, utilizing a rotary seal at the end of the shaft for air or hydraulic connection.
