Typical Applications


Multi-Station Pump Drives
Applications such as this multi-station pump drive with bell housing are ideal for Logan PTO Clutches. OEM and after market designers can take advantage of energy savings and component longevity by utilizing Logan PTOs to drive auxiliary attachments only when required.

Logan PTO Clutches when used with Rear-mounted PTO (REPTO) mounts

Rear mounted PTOs provide live engine power for auxiliary pump drives from the rear of the engine - through a separate PTO drive shaft. The Logan Direct drive PTO clutch bolts directly to the OEMs Rear Engine PTO pad, providing on-off engagement of auxiliary drives.

Mobile Equipment
Logan Advantages:
  • PTO is powered directly from the crankshaft, behind the engines flywheel.
  • Does not require extended front frames, modified bumpers, radiators and drive couplings associated with front PTOs.
  • Eliminates exposure of the PTO and pump to front end collision damage.

How the REPTO works: An idler gear transmits power from the engines drive gear to the driven gear on the engines output or PTO Shaft. The PTO shaft rotates in the same direction as the engine resulting in efficient power.
