Overhaul Kit for the 18 HP 570cc Briggs & Stratton Vanguard V-Twin (72mm Bore) This kit provides the core parts to rebuild the 35-cubic-inch (570cc) Briggs & Stratton Vanguard OHV V-twin. It includes two standard 72mm pistons with 3-piece ring sets, a complete gasket set with seals, two spark plugs, two oil filters, one fuel filter, and engine assembly lube - enough for one engine. Fitment - Verify by Model and Bore, Not Horsepower Fits the 18 HP, 570cc (35 cubic inch) Vanguard V-twin with a 72mm bore. These are model numbers beginning with 35, including 350442, 350447, 356442, 356447, 358772, 358777, 359447, 359775, 359777, and others. Confirm the model and type number stamped on the blower housing and a 72mm bore before ordering. The larger 20, 23, and 25 HP Vanguard engines are a bigger displacement with a different bore and are not covered by this kit, so do not select by horsepower alone. Standard Bore and Assembly This kit is for cylinders at the standard 72mm bore. For a cylinder machined oversize, order the matching oversize pistons. The included assembly lube is for reassembly and break-in; use a piston ring compressor when installing the rings.

  • A complete overhaul kit for the 72mm-bore Briggs Vanguard V-twin: two standard 72mm pistons with 3-piece ring sets, a complete gasket set with seals, two spark plugs, two oil filters, one fuel filter, and engine assembly lube. Covers one engine.
  • Fits the 18 HP, 570cc (35 cubic inch) Briggs Vanguard OHV V-twin with a 72mm bore, models beginning with 35 (for example 350xxx, 356xxx, 358xxx, 359xxx). Verify by your model number and a 72mm bore, not by horsepower - the larger 20 to 25 HP Vanguards use a different bore.
  • Example models: 350442, 350447, 356442, 356447, 358777, 359447, 359777, and others in the 35-series. Find the model and type number stamped on the engine's blower housing and confirm the 72mm bore before ordering.

  • For standard 72mm bore cylinders; if a cylinder has been bored oversize, order the matching oversize pistons instead. Apply the included assembly lube during reassembly and use a piston ring compressor to seat the rings.
