It was introduced to the railroad industry as the prime mover for the new 60- series locomotives. The Model 710 engine has a stroke of 11.0 inches (279 mm) and a bore of 9.06 inches (230mm). Top engine speed has been reduced from the 959 RPM used for the 645F series engines to 900 RPM. The net effect of this change, combined with other improvements, is to reduce the 710's BSFC by 2.5 percent over that obtained with the 645F model diesel engines. (2)
