lubricating system is a pressure feeding system using an oil pump The engine oil is drawn from the oil sump by the oil pump which drives the oil under pressure through the various lubricating points in the engine The oil then returns to the oil sump to repeat the continuous cycle The geardriven oil pump is built into the oil sump The oil is pumped through a spinon type oil filter Model IIAI only
