Briggs & Stratton 12S402-0060-F8 205cc Engine – 3/4in Shaft

Description

Cast with an aluminum alloy crankcase, the Briggs & Stratton 12S402-0060-F8 horizontal shaft engine provides an optimal balance of low weight and mechanical strength on portable contractor machinery. Utility equipment frames crack when fitted with heavy, out-of-balance replacement motors. This 205cc overhead valve engine delivers 9.00 gross torque ft-lbs while keeping overall machine weight low for easy maneuvering around jobsites.

A precision 3/4-inch straight keyed shaft couples directly to industrial pump shafts, belt sheaves, and gear reduction boxes. Splash lubrication delivers motor oil to internal bearing journals, shielding moving parts from friction wear during extended work shifts. The dual-element air cleaner prevents fine dust from entering the carburetor venturi, preserving factory idle settings and preventing fuel mixture contamination.
