Throughout this site we use many technical terms, and given the breadth of readership our site enjoys, sometimes we are remiss and incorrectly assume everyone knows what we are referring to. For those that do not, here are some explanations of the technical terms use.
Hand preparation and assembly of an engine or other mechanical components to ensure correct tolerances are achieved and thus optimum performance obtained. Can include x-ray type techniques used to determine minor imperfections not detectable to the human eye. Commonly includes; Block - Align hone main saddles, parallel boring and honing with deck plates, equal-distance decking; Pistons - Checked for size and dome height and then pin fitted; pistons are notched where necessary for valve clearances,
indexed, machined; oil holes radiused, journals micropolished. The compression ratio is calculated for maximum performance; Balancing - The entire rotary assembly is precision electronically balanced.
