Anyone ever see a non-geared oil pump?
I have never seen any oil pump on any engine going back to designs around since
the early 20th century that were not geared, except for the B&S engine which
uses a scoop on the bottom of the connecting rod cap to supply pressure oil.
genee/rickie claim non-geared oil pumps on engines are common. Anyone know
which engine designs used oil pumps that are not geared?
