Need to remove flywheel on a 19.5 hp briggs and straton engine

Hi,
You must find a way to keep the engine from turning over and then usually with a 15/16" socket loosen the nut. If you do not have the needed puller, back the nut off up to the top of the shaft, take a pair of hammers(one a ball pein), place ball of the ball pein hammer on the tip of the shaft and strike the flat face of that hammer with the other, Something to carefully lever upwards pressure on the outside edge of the flywheel may prove of assistance. Usually one or two blows is sufficient. Do NOT strike the flywheel directly as that will break the stator magnet loose.
Peace,
Clarke
