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 self-adjusting, hydraulically activated LC-314 Bell Housing PTO clutch installed on a Jetstream X Series Waterblaster


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, forcinMechanical PTO clutch with old-style lever armg 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.

Water blasting contractors prefer the Logan Bell Housing PTO since it 19s push-button activation and self-adjusting disc pack simplifies machine operation


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 Push button activation from  a control panel or device is now possible.  Pictured above: Richard Alderson - Jetstream

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.

Logan Direct Drive PTO Clutches Enhance Bow Thruster

Logan Direct Drive PTO Clutches Enhance Bow Thruster

April 13, 2018 Category: Direct PTO, Marine

Steering a commercial boat or large yacht can be similar to driving a heavy car with bad brakes. It’s difficult to stop, and response to the rudder is slow. This poses no problem in the open sea, but it can be real challenge to maneuver the vessel in a congested marina or when docking. This is where a bow thruster comes in. A bow thruster consists of an open-ended tube that runs through the underwater sections of the hull near the bow and perpendicular to the keel. A propeller mounted at some point inside this tube can rotate in either direction. The helmsman selects the rotational direction and actuates the propeller.  As a result, the bow thruster sucks a solid stream of water in one end of the tube and forces it out of the other, pushing the bow sideways and augmenting the rudder to make steering more responsive. Two Props are better than one Traditional single propeller systems generate thrust by accelerating water in the axis of the propeller shaft. However, the water discharged by the propeller also rotates. This is due, in part, to the friction between the surface of the propeller and the water. This rotational component does not produce thrust, but it does consume energy. That’s why Fred Knowles of Hansen Marine, Marblehead, Mass., like the ABT-TRAC thruster from American Bow Thruster, Rohnert Park, Cal. The ABT-TRAC thruster is designed with two counter-rotating propellers. By turning the propellers in opposite directions, the efficiency of the

Jet Boat Fishing in Bristol Bay Alaska

Jet Boat Fishing in Bristol Bay Alaska

Fishing for Salmon in Alaska’s Bristol Bay can be a challenge all by itself. This area is a Sport Fisher-man’s paradise so the area is filled with commercial as well as pleasure fishing boats during the season. Being able to maneuver fast in these waters is a plus. Steve Tutt has owned many Jet Propulsion fishing boats and has made a name for himself in this area of the world. Steve has found that Jet Propulsion fishing boats idea for the conditions found in the Bay. One thing Steve found out that fishing in crowded waters can be a bit of an issue with Jet Propulsion. Controlling the Jet Boat and nets in neutral position can be a problem since the boat tends to circle. It would be easy to snag a line or another fisherman’s net. Steve began looking for solutions to see what could be done.   His efforts first lead him to the option of retrofit-ting one of his boats with a Marine Gear. Although possible the cost would be in the 6K to 8K range plus the cost to retrofit. Besides that the weight to Horsepower ratio would be affected by this change. Not a good solution. Both of these issues did not make this option appealing since he was looking at changing 5 to 6 vessels. Steve also looked at mechanical options but none would give him the flexibility to control everything from the boats wheelhouse. Steve then began looking at the Bell Housing Logan Clutch option for a solution. p.p1 {margin: 0.0px 0.0px 19.0px 0.0px; line-height: 10.5px; font: 11.0px Helv
