New! Logan Bell Housing PTO Clutches

Self-Adjusting PTOs for Industrial, Marine, Agriculture, Off-Road and Mobile Equipment

Logan, a leader in SAE PTO Clutches for auxiliary and direct drive applications, Introduces a self-adjusting, heavy-duty Power Take-Off assembly for internal combustion engines The Logan Bell Housing PTO is fluid or air actuated; mounting to a Gasoline or Diesel Engines flywheel. Logan Clutches - 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 separator and friction discs and maintain a running clearance between separator and friction discs. The amount of pressure applied, regulates the amount of torque transmitted through the clutch. Logan PTOs are designed to factory or field retrofit with existing Twin Disc® style and Rockford style mechanical PTO's. The Logan system eliminates mechanical linkages, and utilizes the same Twin Disc® Bell Housing, Shaft, and bearings making field retrofits quick and easy.
