Cat 3512 Front of Engine PTO

   900-5910 clutch assembly including brackets

Logan Clutch has partnered with multiple OEM's for front of engine power take off PTO's.

One popular application is with the Caterpillar 3512B and 3512C engine (1100-2551bhp/820-1902kW) This main propulsion engine is available from Caterpillar with a front, left, top SAE J744 "C" pad to mount a hydraulic pump.

OEM's have partnered with Logan to solve a range of common problems including:

1) Disengages pump when not in use saving pump wear and tear. Less maintenance.

2) Removes pump load from engine when pump is not in use. Saves fuel.

3) Disconnects the pump if there is a hydraulic system leak and allows the engine to continue to run. Greener.

4) Simplifies cold starts of main engine. Just make sure the clutch is not engaged. Simpler systems.

5) Reduces noise from hydraulic systems running needlessly. Better for operators.

Clutch Driven PTO Engine Mounted Pumps

THE CHALLENGE To Help an OEM develop their own product line of mobile equipment for oil and gas retrieval.  This  complex equipment is self- contained but has many functions that must be performed at the same time. This equipment will be Company owned, engineered, and maintained.  This direct line of communication gives us options we would not always be granted. The challenge presented was to control the engine mounted pumps connected directly to the rear direct drive PTO pads. At present these pumps cannot be controlled except by stopping the engine. This is not an acceptable solution for the multiple functions required by the engine. These pumps are only required for short periods of time to deliver a slurry mixture.  With the clutches both pumps can be used only as required by hydraulic actuation. By adding the clutches to each pump both pumps can be used at the same time or individually as required. THE SOLUTION The pads on the engine were an SAE standard. Logan

Flywheel Mounted Logan PTO Replaces Mechanical on Tug

May 20, 2014 by Ed Gallucci

When Canadian towing and barge services provider Island Tug and Barge encountered problems with the mechanical clutch system on one of its tugs, it turned to Logan Clutch to provide a solution.  Island Tug, based in Vancouver, British Columbia, offers towing and barge services, including ramp-equipped deck barges, aggregates and general cargo, as well as cable installations. The company’s towing services extend to the Pacific Rim, and it also has facilities on Canada’s eastern seaboard. Island Tug had been running two generator sets on the tug Island Scout. These ran pumps for the main hydraulics and bow thrusters off the back of the engines. In order to do this, both engines were equipped with conventional, mechanical lever actuated PTO clutches to drive the pumps.  The problem was that these clutches started to fail during full rev/min engagement. Generator sets normally run at 1,800 rev/min and cannot be slowed down to allow for clutch engagement. These failures
