DANA CORPORATION

A new four-page brochure de- scribing the Wichita® mechanical power takeoff (PTO) that transmits and disconnects power from heavy- duty diesel engines is now available from the Power Transmission Divi- sion of Dana Corporation, Toledo,

Ohio.

Highlighted in the brochure are the Wichita PTO's design advan- tages, including its incorporation of the heavy-duty Spicer® Angle-

Spring® clutch for automatic self- adjustment and constant plate load throughout the wear life of the unit.

The brochure also describes typical

PTO applications, and gives de- tailed instructions for PTO selec- tion. Included for quick reference are PTO selection charts for the major makes of diesel engines.

Complete engineering and dimen- sional information for the PTO are provided in line drawings accompa- nied by tables. Also included are toll-free numbers of regional sales offices where additional technical information may be obtained.

ELECTRO-MOTIVE

DIVISION

A General Motors Electro-Motive

Division production marine drilling power unit, incorporating the EMD 20F9B 20-cylinder engine, has suc- cessfully completed the Det norske

Veritas 15-degree permanent incli- nation test. The DnV approval ap- plies to EMD's complete line of nat- urally aspirated and turbocharged engines, as applied to the drilling power unit configuration.

The test, which consisted of 12 hours of running time at full rated horsepower and speed, was wit- nessed by officials from DnV. the

American Bureau of Shipping, and

Lloyd's Register of Shipping. The test is mandatory for generating sets used on offshore rigs and platforms requiring DnV certification.

FOR DIESEL ENGINES

BMEP BALANCER MODEL 300-A

STEADY • ACCURATE • REPEAT ABLE • RELIABLE

SPECIAL FEATURES

EASY TO USE • Attaches to standard indicator valve. • Completely passive system thor- oughly reliable for extended ser- vice. • Balances load distribution in a multicylinder engine with preci- sion and ease. • Reading of pressure gauge gives index of power developed in cylinder. • Fuel rack can be adjusted up or down while watching gauge move to desired setting. • Results in a smooth running, effi- cient engine that sounds right. • Rugged construction of stainless steel, yet light in weight. • Requires no maintenance. • May be used to indicate engine loading for a remote installation having calibration chart for en- gine. Reading needs no correction for ambient temperature or alti- tude.

Lube oil and cooling water pres- sures and temperatures remained constant during the test. Normal engine start was achieved prior to initiation of each 6-hour test, and clear exhaust gases were observed throughout the entire load testing.

ELLIOTT COMPANY

The Elliott White Gill Thruster and propulsion unit is a low-head, high-volume axial pump capable of delivering thrusts of up to 38,000 pounds in every direction—through a full 360 degrees.

It mounts flush with the hull, below the vessel's draft line, open to the water at both suction and dis- charge ports. Units are fitted in the bow section and/or the stern, de- pending on application. Thrust is produced by drawing water through the intake, and discharging it on an almost horizontal plane through a deflector that rotates a full 360 degrees. No part of the system pro- trudes below the vessel's keel line.

The Elliott White Gill unit, in horizontal, vertical, "T3", and cross shaft designs, gives ships of even- class precision maneuverability in hundreds of applications offshore and on inland waterways around the world.

Drivers for thrusters can be diesel engines, ac or dc motors, or hydrau- lic motors. The diesel engine is an ideal driver because it is variable- speed. and requires no support sys- tem to furnish its power. As a result, diesel engines are the selected driver for a large percentage of Ellott's thruster applications.

When Elliott Company decided to package its cross shaft model with a driver, the diesel engine was the obvious choice. By mounting an en- gine bracket on the thruster. the engine could be mounted piggyback fashion, with its drive shaft parallel to the input shaft of the thruster.

Selection of appropriate sheaves ac- complishes the desired speed match, and varying the engine speed per- mits throttling of the thruster.

Because the White Gill perform- ance follows a typical pump curve, the speed varies much less than the horsepower and thrust as the engine is throttled. For instance, if 50 per- cent of the thrust is required, the horsepower requirement is only 35 percent and the speed drops by only 29 percent. A variety of engines are used, depending on customer pref- erence.

FAIRBANKS MORSE

Colt Industries' Fairbanks Morse

Engine Division in Beloit, Wise., continues to be the leading manu- facturer of medium-speed, high- horsepower diesel engines in the

U.S. With a range of 640 to 29,286 bhp and the ability to burn a wide variety of fuels, these engines are widely accepted in both the marine propulsion and stationary power marketplaces.

Fairbanks Morse has strength- ened its entire parts and service operation to improve all aspects of customer service worldwide. All

Parts and Service Centers are com- puter-integrated with the main plant in Beloit to quickly process orders for stock items or special made-to-order parts.

Capabilities of these service cen- ters include engine rebuilding and individual component repair. Com- plete fuel injection service available at the Reno, Nev., facility allows

FM to stock rebuilt and exchange assemblies in all locations to complement its parts inventories.

With diesel engines available for instructional use, FM's Diesel

Training Center provides customer personnel with hands-on service training on opposed-piston and

Pielstick engines. Training special- ists guide students to better under- stand and perform necessary steps for proper engine maintenance.

Fairbanks Morse's Electrical En- gineering Department offers control and systems design capabilities for engine gauge and alarm panels, bearing temperature monitoring systems, and engine-generator con- trol panels. Panels and systems as- sembled and tested by skilled craftsmen provide trouble-free con- trol of engine operation.

FALK

The Falk Corporation of Milwau- kee, and Zahnraderfabrik Renk AG of Augsburg, West Germany, re- cently signed a license agreement under which Falk will have exclu- sive manufacturing, sales, and dis- tribution rights in the U.S. for the

Renk Series AWS reverse/reduction drives. In addition, the two compa- nies have agreed to cooperate on custom design marine propulsion drives, primarily for Naval applica- tions in the U.S.

For many years, both Renk and

Falk have demonstrated design, manufacturing, and application ex- cellence in marine main propulsion gear drives. The combined strengths of the two companies will enhance the products offered to the marine industry, both in standard and cus- tom design drives.

The Falk Corporation, a subsid- iary of Sundstrand Corporation, is a leading producer of gear drives and flexible couplings. Renk is a subsid- iary of GHH, one of the largest engi- neering groups in Europe, and is well known worldwide for the spe- cial-purpose marine propulsion gears.
