New Twin Disc Transmission For High-Speed, High-Output Use

Twin Disc introduced the MG-5202DC (Deep Case) transmission for use with high-speed/ high output diesel engines in heavy duty and intermediate applications including commercial workboats, fishing boats and military ves- SQIS The MG-5202DC is a vertical offset (400 mm/ 15.74-in. drop), single-reduction marine transmission covering a range of 368 to 731 kW (493 to 980 hp), available in ratios of 4.03:1, 4.59:1, 5.04:1, 6.10:1, 6.55:1 and 6.96:1. It can be operated at full rated capacity in either forward or reverse for ahead propulsion when installed on standard right hand rotation engines. It is equipped as standard with 14- or 18-in. torsional couplings and reportedly offers solid, predictable response through oil-controlled, oilcooled clutches. Other standard features include precision single helical gearing for smooth, quiet operation and oil filter/strainer. Accessibility for maintenance was stressed in the design: it is not necessary to remove the transmission or disturb alignment for most service functions. Twin Disc's popular trolling valve option offers the ability to obtain propeller speeds lower than possible at engine idle with the clutch fully engaged. A live PTO option rated 112 kW (150 hp) at 1,800 rpm is also available.
