That’s not the crankshaft output gear in your photo.. See the photos below. The output gear drives a short layshaft on the bottom of the engine which takes power to the clutch. The oil pump drive is off the other side.
There is a second layshaft at the top which drives the cooling fan, distributors, etc.
