American LaFrance » 300 Series

In 1931, American LaFrance astounded the fire service - and the rest of the fire apparatus industry - with its surprise announcement of a V-12 engine. Designed for the unique requirements of the fire service, the 312-A engine had been under development at Elmira for more than three years. With four-inch bore and five-inch stroke, the big V-12 displaced 754 cubic inches and delivered an impressive 240 horsepower. Actually two six-cylinder engines shring a common crankshaft, the 312-A engine had an extremely narrow bank angle of 30 degrees. The first production American LaFrance V-12 pumper was delivered to Winfield, Kansas, in August, 1931. With the new V-12, American LaFrance replaced the 1929-1931 Master Series with a new 300 Series. The 240-horsepower 312-A engine also permitted American LaFrance to market its first high-capacity 1500 gallon-per-minute pumpers, the first two of which were constructed for New York City.

During the early to mid-1930s, American LaFrance abadoned its long-favored rotary gear pump in favor of a single-stage centrifugal pump purchased from the Buffalo Steam Pump Co. The company also converted from outdated chain-drive to more efficien bevel gear shaft drive propulsion for its motor fire apparatus.

    WOW! The Metropolitan shown in the second and third photos belonged to me at one time. I sold it back to the Vigilant Company at Great Neck, Long Island. It's great to see what a wonderful job they've done with the restoration. They told me when they purchased it their intent was to make it the center piece of a museum they were going to create. What a great beauty she is again! I hope I can get to Great Neck to see her again. My daughter has a photo on her Facebook page of me and her in the front seat as we roll down the main street at a Christmas parade in St. Petersburg, FL.
