The EMD 567 is a line of diesel engines built by General Motors' Electro-Motive Division. This engine, which succeeded Winton's 201-A, was used in EMD's locomotives from 1938 until its replacement in 1966 by the EMD 645. It has a bore of 8.5 in (220 mm), a stroke of 10 in (250 mm) and a displacement of 567 in³ (9.29 L) per cylinder. Like the 201-A, the EMD 645 and the EMD 710, the EMD 567 is a two-stroke cycle engine. It is a V engine with an angle of 45° between cylinder banks.
567AC engines (an "A" block upgraded to "C" block specifications) and 567BC engines (a "B" block upgraded to "C" block specifications), as well as 567C and 567D engines, may be upgraded to use 645 power assemblies, theoretically achieving an increase in horsepower.
As 645 power assemblies are more readily available than 567 power assemblies, this upgrade may also be employed in so-called "life extension" programs.
EMD's chief competitor, GE, now makes EMD-compatible replacement parts.[1]
