As for the components of the "TR" Series Clutch, the torsionally resilient air gland tube is made of durable neoprene elastomer, rein- forced with eight-ply polyester cord, formed and cured on Haley MGI designed and constructed precision molds. The tube provides excellent strength, durability and torsional resilience.

Marine Gears reports that wheth- er a new rim rolled and finish- machined by MGI, or a rim remanu- factured with new welded replace- ment registers finish-machined to original tolerances, every "TR" Se- ries Marine Clutch rim meets equal- ly exacting engineering and manu- facturing standards.

The air gland tube is formed, cured and bonded onto the rim resulting in a rim-tube combination which provides a tough torsionally resilient air gland foundation for excellent friction shoe positioning, before, during and after clutch en- gagement.

MGI, founded in 1973, also offers

Haley "TB" Series Clutches for use in exceptional high-torque applica- tions. The "TB" Series is very ver- satile because they are interchange- able with all torque bar series ma- rine clutches. The hard rubber- coated torque bars and induction- hardened side plate holes reduce wear.

MGI claims that excluded alumi- num shoes provide higher strength and reduced weight. "TB" Series clutches and drums are available in stock for immediate delivery in new or remanufactured sizes 14-inch through 32-inch "TB" wide series and 20-inch through 42-inch "TB" narrow series. Split tubes are also available.

Marine Gears, Inc., an American

Gear Manufacturers Association- certified manufacturer, offers a wide range of marine clutches, as well as marine gears. For a free bro- chure detailing MGI products,
