Abstract
The invention relates to a method and mould for the production of a connecting rod or similar object having a body of cast metal, expecially a non-ferrous metal such as a zinc or aluminum alloy, the body comprising a connecting rod shank and of which at least one connecting rod end is provided with a bearing race element of hardened steel, typically an outer race for a roller or needle bearing. The invention particularly pertains to connecting rods having bearing surfaces subject to high loads and which are characterized by the absence of 'pockets' in which contaminated lubricant might accumulate. Such connecting rods are, for instance, used in two-stroke combustion engines as for instance outboard motors for boats or the like, with rollers or needles disposed between the said outer race and the journal of the crank shaft throw.
