Abstract
Abstract A pump has a rotating shaft supported by a pair of bearings. An oil sump is located below the shaft and contains oil for lubrication of the bearings. Roll pins are inserted into respective holes in the shaft to extend into the oil sump during rotation of the shaft to thereby throw oil for lubrication onto the bearings.
