Case 4016 Mower, Lawn and Garden Tractor

Briggs Vanguard 303447

You will have to use the muffler and manifold, and stub shaft off of your original engine. If you replace the 303447 with a 356447 engine, you will also need to replace the flywheel, fan, blower housing, and starter gear with parts from your old engine. The flywheel fan and housing is 1-3/8" thicker on this engine than the 303447 series and the old parts are needed for fitment.
