The oil pump gear is plastic and should be near silent.
I have never known one fail but that means nothing really, there is a first for everything.
Also those mechanics stethoscopes can be a bit terrifying on an old air cooled engine that is mechanically noisy at the best of times.
Check for oil flow at the head by undoing the check bolt, this will rule out the pump at least.
