Briggs & Stratton 3.5HP Torque Specs

Engine specs

• The 550 series single-stroke engine's displacement is 127 cubic centimeters with a 2.44-inch bore and a gear-driven lubrication system to continuously supply oil to all internal parts.

Capacities

• The 29.5-pound engine holds 0.5 gallons of unleaded gasoline and 20 ounces of 5w-30 SAE oil.

Products

• The 550 series engine has a horizontal shaft and is used for powering front-tine tillers and lawn edgers.

Torque

• Torque is calculated mathematically using the engine's revolutions per minute as the major source of data. There isn't a tachometer for reading the engine's rpms on this engine, so the company's specs are to be accepted as given. Briggs and Stratton listed the gross torque for the 550 series engine at 5.50 foot-pounds. Additionally, altitude has a direct effect on power output, which in turn will influence torque.
