Power Take-Offs

The Power Take-off is suitable for inline and sideload applications on all internal combustion engines with standard SAE flywheel housing dimensions. All PTOs and parts are 100% interchangeable with existing PTOs. All units are supplied with sealed ball pilot bearings to eliminate lubrication problems normally encountered. Ball bearing throw-out collars are optional on 14" units and standard on 311 units. Please pay close attention to certain application criteria including speed, side load and clutch torque.

Hydraulic P.T.O.'s

Actuated with hydraulic pressure and internal components immersed in oil, this line of clutches and brakes is ideal for applications that require high cycle rates and or high speeds.

The oil film aids in transmitting the torque until the unit is fully engaged. The heat generated during engagement is transferred to the oil and is transmitted away from the working surfaces by the circulating oil.

Features of hydraulic units are:

  • Long component life, wear is virtually non-existent
  • Maintenance intervals increased by a factor of 5 to 10 times
  • Low driven inertia
  • Faster response speed
  • Higher cyclic rates and operating speeds than standard air actuated dry running units

Hydraulically actuated units with internal dry running components are also available.

Mechanical P.T.O.'s

Mechanical P.T.O.'s are powered by a 2-plate clutch. Built-in damping springs on the clutch; driven discs and no pilot bearing are some of the standard features that make mechanical P.T.O. user friendly when applied in the harsh environment of diesel engines.

Highlights of our mechanical P.T.O.'s are:

  • Adjustment free feature automatically adjusts the clutch
  • In-line and side-load bearing carriers
  • 30 Lb. handle pull to engage clutch

Pneumatic P.T.O.'s

Pneumatic (Air) P.T.O.'s are powered by heavy-duty Standard Vent clutches. With large friction areas for high energy starts and an air actuated clutch for remote or automatic control of the PTO.

The air actuated PTO is ideal for your application because:

  • The bearing supported shaft eliminates sideload on the crankshaft
  • The high speed air tube not affected by centrifugal force
  • There are no o-rings or diaphragms to wear out
  • 14" and 18" 1, 2 & 3 plate clutches available
