Logan Power Take-Off (PTO) Clutches 

Simple, Efficient, High-Torque Design

Logan PTO’s are used in a variety of Mobile, 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.

PTO Clutch Applications

• Single and Multi-Station Pumps
• Hydraulic Pump
• Logan PTO Clutch with Softstart^TM Engagement
• Mobile or Stationary Auxiliary Drives
• Connect / Disconnect Direct Drives
• Winches, Reels, Hoists and more

Features

• Logan Softstart^TM   Engagement
• Heavy-duty, self-contained corrosion resistant design requires no external lubrication
• Air or Hydraulically actuated; self-adjusting, multiple disc pack design
• Smooth engagement / disengagement
• Simplified, compact, high torque design
• Remote activation from a control panel or operator’s station
• Optional manual engagement screws in case power flow is disrupted
• Optional shaft adapters for Dana style flanges
• American Bureau of Shipping (ABS) type approval
• Oil bath or flow through cooling

Advantages

• Reduces fuel consumption and CO2 Emissions by engaging drives and pumps only when required
• Quicker Starts: Lowers horsepower draw and cranking power required during machine start-up by disconnecting the hydraulic system from the engine
• Reduced ambient noise through intermittent use of pumps and equipment
• Cooler running hydraulic systems: Heat is generated whenever oil dumps from high to low pressure without producing work.
• Disconnecting the PTO Clutch reduces the destructive effects of heat – lowering maintenance costs and hydraulic oil requirements
• Extends the life of drive systems and components 
   

Power Take-off Clutch Mounting Options

Direct Connection to Power Source

The PTO clutch is directly mounted to the power source via the SAE standard flange. The auxiliary pump mounts directly to the output of clutch, utilizing the same SAE standard flange. 

402 Series: Remote Mounting of Auxiliary Pump 

Overhung load adapter mounts to the output of the PTO Clutch assembly and allows for moderate side load induced by a cardon shaft. 

405 Series: Remote Mounting of Consecutive PTO Clutch and Auxiliary Pump

Utilizing the Logan 405 Series companion flange adapters, the remotely mounted PTO clutch input interfaces with a standard Spicer-type flange on a sliding joint cardon shaft.

Combination of 405 and 402 Series:

Cardan shafts mounted to both sides of the PTO clutch utilizing a 405 Companion Flange on the input and 402 Overhung Load Adapter on the output.

Universal Front of Engine PTO for All Engines 

Logan Universal Front of Engine PTO’s incorporate an integral  flexible coupling, clutch cardan shaft and bracket arrangement. Works with most new and legacy engines and can be installed with fewer alignment procedures.
