Twin Disc Announces Two New Transmissions —Literature Available

Twin Disc, Incorporated, a leading manufacturer of marine transmission in the 52 to 1,193- kw (70 to 1,600-hp) range, announces the availability of shallow- case ratio versions of both the MG-518 and MG-520 marine transmissions.

Three ratios for the MG-518 have been added which are ideal for crewboats and similar intermediate- duty, high-performance vessels for above 522 kw (700 hp) at 2,100 rpm. These new ratios include 2.00:1, 2.47:1 and 2.94:1.

The MG-518 reaches down to the power range midway between the MG-520 and the MG-514. The MG-518 is approved for use with the Caterpillar 3412T and 3412TA (limited ratios), the Cummins KTA-1150, the Detroit Diesel 16V-71, and other compatible marine diesel engines.

Four ratios have been added in the shallow-case version of the MG-520. These include 2.02:1, 2.97:1, 3.44:1, and 4.03:1. Initially this model is being recommended for heavy-duty crewboat service in the lower 671 kw (900 hp) range at 2,100 rpm. The MG- 520 is adaptable to Caterpillar 3412TA and D-353 engines, the Cummins VTA-1710-M2, the Detroit Diesel 16V-92, and other compatible marine engines.
