Abstract: An oil sump is disclosed for a structural engine of an agricultural vehicle. The underside of the sump is formed with a longitudinally extending downwardly concave tunnel to accommodate a propeller shaft. The tunnel divides the interior of the sump into two oil trays arranged one on each side of the tunnel. Oil passages are cast into the sump to connect the two trays to a common recirculation duct that leads to the intake side of the engine oil pump.

Abstract: An engine block 10 is disclosed having machined front and rear faces. Each of the front and rear faces is capable of receiving and sealing against a housing (20,40) enclosing a gear train for coupling the engine crankshaft to a camshaft of the engine. The front face is additionally capable of directly receiving and sealing against an engine front cover while the rear face is additionally capable of directly receiving and sealing against a flywheel housing. In this way, the same engine block may be selectively assembled into an engine having a front mounted or a rear mounted camshaft gear train.

Abstract: An engine block is described having at one end a lateral flange 12 formed with an aperture for mounting of an ancillary unit such as a pump 16. An adapter plate 30 is mounted on the end face of the lateral flange to overlie the aperture for the ancillary unit 16, the surface of the adapter plate facing the aperture being machined to mate, when in use, with an ancillary unit 16 disposed on the other side of the flange 12 and secured to the adapter plate 30 through the aperture in the lateral flange.

Abstract: An integral cylinder block is provided having features which enhance structural stiffness, thereby reducing noise emissions. The block includes an upper portion with cylinder bores and a lower portion forming at least a part of a crankcase. At the upper and lower portions of the block, the casing has sculpted wall portions with a curved, undulate shape. At a side of the cylinder block, a closed oil cooler cavity is formed. A wall is provided to generally separate the oil cooler cavity from the water jacket defined within the block. An opening is provided in the wall, but the opening is distally located relative to a water pump outlet that provides a flow of coolant into the cavity, thereby improving the flow direction of coolant across the oil cooler. Also, an opposite side of the cylinder block includes a closed tappet cavity to accommodate pushrods.
