A gear-type lubrication pump for an internal combustion engine wherein the pump housing and oil porting are formed in the engine block and one pump gear is rotatably supported in a bushing mounted in the engine block. The other pump gear is rotatably mounted on a bearing supported in the pump housing on a fastener which also locates a cover plate and seal in position to abut the outside face of the one gear and prevent leakage from the pump housing.

A multi-part fastener assembly for attaching a first apertured member such as a valve cover to a second member such as a cylinder head, comprising an elongated threaded fastener, a tubular sleeve encircling the threaded fastener, and a rubber grommet encircling the sleeve. The grommet's outer surface is cylindrical for facilitating its insertion through the valve cover's aperture. However, a bead formation created on the grommet's inner surface is engaged upon insertion of the sleeve member through the grommet to cause the lower edge portion of the grommet to be biased radially outward in a manner which secures the sleeve and grommet in the aperture. In addition, the sleeve's upper end portion has a surface extending obliquely to the axis of the sleeve so that when pressed against the grommet by tightening of the fastener the rubber grommet material is distorted outwardly. Further tightening of the fastener seats the lower end of the sleeve member against the associated cylinder head to limit the stress imposed upon the rubber grommet by the sleeve.

A gasket for sealing the connection between a cylinder head and a valve cover. The gasket has a sheet metal backbone having a main body with spaced stations having holes therethrough for cap screws fastening a valve cover to a cylinder head. A finger-like tab extends inwardly from the stations. Each tab has a cap screw hole at the distal end thereof. The tabs are bent back over the main body so as to be in contact with the spaced stations and with the holes in the tabs and stations in alignment. The backbone has a rubber based material subsequently molded therearound. The result of the folded construction is a double thickness of metal in the areas surrounding the cap screw holes to form positive stops to limit the compression loads applied to the rubber based seal of the gasket by the cap screws when the valve cover is fastened to the cylinder head. The compression loads are thereby limited and the gasket is protected from damage by excessive loads so that effective sealing and long service life is assured.

An engine, preferably of the heavy duty diesel internal combustion type, is provided with a crankcase having downwardly extending side walls interconnected by a stiffening bridge member. The bridge member includes integral mounting means for an oil pump and its drive shaft and supports a drive gear that directly engages a driving gear on the engine crankshaft immediately above the assembly.
