The Model, Type, and Code numbers are stamped on the engine's blower housing or cylinder head. Model number tells you the engine family. Code number's first two digits tell you the year of manufacture (07 = 2007).

WHEN TO CHOOSE THE MASTER MECHANICAL KIT This kit is the right choice when: Your rebuild inspection shows worn or damaged connecting rods Intake or exhaust valves show significant wear, pitting, or valve stem wear You want to replace all wear-prone mechanical components at once for maximum longevity You're doing a professional-grade rebuild that includes rod bearing and valve seat service If your rods and valves are still in good condition, the Rebuild + Tune-Up Kit is a better fit (adds routine service items instead of expensive mechanical components). ENGINE SPECIFICATIONS Engine type: 4-cycle, gasoline, OHV Configuration: 90-degree V-Twin Bore: 68mm (2.68\") Stroke: 66mm (2.6\") Displacement: 480cc (29.3 CI, marketed as 30 CI) Rated power: 12-16 HP depending on model EQUIPMENT APPLICATIONS These Briggs Vanguard 30 CI V-Twin engines were installed as OEM equipment on commercial and residential outdoor power equipment from the mid-1990s through 2007, including commercial mowers, generators, pressure washers, welders, agricultural equipment, and industrial machinery. INSTALLATION NOTES Use a piston ring compressor when installing new pistons. When installing connecting rods, verify crankshaft journal condition – damaged or scored journals require crankshaft service. When installing new valves, lap the valve seats using valve lapping compound to ensure proper seating. Follow Briggs Vanguard service manual torque specifications for connecting rod bolts, cylinder head bolts, and valve cover fasteners.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eMASTER MECHANICAL OVERHAUL KIT FOR BRIGGS VANGUARD 30 CI V-TWIN ENGINES – Comprehensive mechanical rebuild kit for full top-end and rod\/valve service.
