    Abstract: The description relates to a crankcase made of light metal for an internal combustion engine with a parting plane (4) running through the crankshaft axis between a case upper part and a case bottom part, whose bearing walls (2), which connect the case outer walls (1), are provided with inserts (3) made of an iron material, in which the bearing shells of the crankshaft bearing and the bearing bolts (7) provided on both sides of the bearing shells are borne. To achieve favorable construction features it is suggested that the bearing walls (2) forming a continuous light metal bridge between the case outer walls (1) accommodate the inserts (3) that are lower than the bearing walls (2) in recesses (8) starting from the parting plane (4) and are provided, in the area of the bearing bolts (7), with through holes (9) for the bolt heads (10).

    Abstract: For a process for fracture separating the bearing cover of a multi-part bearing arrangement, particularly in crankcases of internal-combustion engines, by means of a half-mandrel in a bearing bore partially bounded by the bearing cover, for separating integrally constructed fastening flanges of the bearing cover from the remaining part of the bearing arrangement, it is suggested for producing fracture separating surfaces in planes sloping with respect to one another that the pairs of corresponding fracture separating surfaces of the bearing cover and the remaining part of the bearing arrangement are produced in separating areas which together enclose an obtuse angle (.alpha.) having a case-side vertex by at least one half-mandrel whose curvature radius, as a function of the respective obtuse angle (.alpha.), is selected to be by 0.5% to 5% smaller than the constant radius of the bore receiving the half-mandrel.

    Abstract: A replacement cylinder for the remanufacture of cast iron engine blocks includes a sleeve formed of cast iron and having a relatively thin wall, a selected length, an outer diameter to achieve a slight clearance of fit within an overbored cylinder, an inner diameter equal to the original specifications of the original manufacturer of the engine block, and a helical cross hatched inner surface finish. The replacement cylinders are manufactured by placing an unfinished sleeve in a boring fixture, boring the inner surface to a selected diameter, transferring the bored sleeve to a honing fixture, and honing the inner surface to the required diameter and surface finish. An adhesive is applied to the prefinished replacement cylinders and the overbored block cylinders, and the replacement cylinders are inserted into the overbored cylinders wherein the adhesive is allowed to cure to thereby adhesively retain the replacement cylinders within the block.

    Abstract: These crankshaft bearings consist of a light-metal alloy and are formed by a bearing section of a crankcase and a bearing cap. In order to avoid a bearing clearance causing noise, a core made of iron metal is poured at least into the bearing cap, said core, by means of a bearing area, directly surrounding the crankshaft journal of a crankshaft, and having lugs for bores connected by a transverse part. The bores are penetrated by the screws in order to fasten the bearing.

    Abstract: The problem of cracking in scantlings of aluminium or aluminium alloy engine blocks by direct and torsional forces applied thereto by a crankshaft is mitigated by casting, into the scantlings, reinforcements of a ferrous material. Each reinforcement includes threaded bosses for receiving the bolts which hold an associated cap onto the scantling and also flat elongate members which extend into the scantling. Since the threads are of a ferrous material, they are more resistant to damage than similar threads of aluminium or aluminium alloy and the elongate members spread the loading throughout the scantling, so reducing the tendency of these loads to crack the scantling. This technique can be of particular benefit where an engine is being modified in a way which produces increased stresses; for example where a petrol engine is being converted for use as a diesel engine.
