Logan Direct Drive Power Take-off (PTO) Clutches

How They Work:  

Direct Drive PTO’s are self-contained, fluid or air activated clutches, positioned between a live PTO pad and hydraulic pump.

PTO Clutch Advantages:

• Reduces fuel consumption and CO2 emissions by engaging drives and pumps only when required
• Better Engine Starts: Reduces 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 service requirements
• Extends the life of drive systems and components
• Standard PTO clutches available in B, B-B, C, C-C, and other popular sizes

Logan self-adjusting, hydraulically actuated Bell Housing Power Take-Off (PTO) clutches have been standard equipment on OEM marine and mobile equipment for over 18 years. Thousands of Logan units are in the field, operating on airport snow blowers, highway and airport marking and runway rubber removal equipment, and more recently trailor mounted waterblasting equipment. 

Logan Bell Housing PTO’s are  hydraulically actuated, and self-adjusting, eliminating the need for mechanical levers, pins, yokes and other high wear items on your chipper. No Levers! Switch your clutch on and off, from the engine control panel or from a remote device.

Logan Vs. Mechanical PTO’s

Logan Clutches are air/fluid actuated and self-adjusting. Lever arms are completely eliminated. Clutches engage at the flip of a switch on your engines control panel or remotely from your truck cab. Mechanical lever arms, yokes, collars are eliminated. 

Logan Clutch engagement is smooth and positive after hundreds of hours of use – regardless of what operator is running the machine.

Untrained operators to slam mechanical clutches into gear at high rpm’s, or they over or under adjust the mechanical clutch which leads to catastrophic failure – and a return to the rental yard for repair.

Logan self-adjusting clutches provide smooth, consistent engagement over hundreds of hours. 

Logan vs. Mechanical PTO’s

The advantage of the Logan Clutch is its ability to engage and disengage the water jetter hydraulically, through push-button activation, eliminating the use of a mechanical hand lever or yoke type clutch engagement system, which dates back to the early 40’s. Smooth, Logan SOFTSTART engagement eliminates clutch downtime due to over and under adjustment. And since the Logan clutch is self-adjusting, clutch engagement is smooth and consistent after hundreds of hours of use.

The mechanical clutch requires the operator to “hand engage” a clutch, which opens up the opportunity for untrained operators to slam the clutch into gear at high rpm’s. Another mode of failure is when operators will over or under tighten the adjusting collar on mechanical clutch to the point where the clutch is too loose and slips to failure or is over tightened and never disengages. Unfortunately, this happens during operating conditions, forcing the water jetter to return to the rental yard, leading to unproductive downtime, inconsistent operation and the endless frustration of machine renters, service center owners, and mechanics.

Making the Switch from Mechanical to Logan

Jetstream / FS Solutions Rental Center Makes the Switch from Mechanical to Logan

“Making the switch was easy”, says Richard Alderson of the FS Solutions, Hammond Indiana Office, “we pulled the old Mechanical Clutch and drive ring, along with all of the linkages, levers and yoke, and replaced the clutch with a Logan RP 314 Series clutch.” The Logan design uses the same shaft, drive ring and taper as the mechanical clutch, making the changeover relatively quick and easy. “All we had to do was install the Logan Bell Housing PTO Clutch, a power pack, and an on/off switch, and within a few hours we were ready for service” says Alderson. Logan Clutch would like to thank FS Solutions, of Hammond, IN for allowing them to retrofit the new self-adjusting PTO on the Jetstream X-Series unit. 

Logan Push Button Actuation - Eliminates Mechanical Linkages 

Logan clutches are simple to operate. Push-button activation engages the clutch from a control panel or remote operating device. Hydraulic or pneumatic pressure via the Logan hydraulic power pack and maniford, clamps the cylinder and piston inside the clutch, which then engages the friction and steel separator discs with a Logan SOFTSTART™ feature - smoothly engaging the clutch. When pressure is removed, release springs separate the clutch, giving it ample running clearance while disengaged. Push-button, remote activation from a control panel, or cab is now possible.
