to the offset design of the present disclosure bearing 28 may include additional features that facilitate lubrication in particular as crankshaft 16 begins to turn oil from a high pressure pump not shown may be pumped axially into crankshaft 16 and radially outward through bearing 28 via one or more passages 44 referring to fig4 and 5 this arrangement may help to maintain lubrication at the interface between outer surface 30 of bearing 28 and running surface 34 of second end 26 of blade rod 14 b passages 44 may be further defined by annular grooves 42 referring to fig4 for carrying return oil referring to fig4 if desired grooves 42 may be formed within outer surface 30 and or inner surface 32 of bearing 28 between outer and inner lands 33 35 a plurality of smaller grooves not shown may be defined in outer surface 30 of bearing 28 and may be interconnected with grooves 42 defined between outer and inner lands 33 35 of bearing 28 for example the smaller grooves may interconnect perpendicularly to grooves 42 defined between outer and inner lands 33 35 oil leaving grooves 42 may spread laterally to provide lubrication at the interface between outer surface 30 of bearing 28 and running surface 34 of second end 26 of blade rod.
