Choose the specific repair or build scope before completing a parts order.Main and Rod Bearings: Measure the AssemblyMatch the bearing to the engine family, journal position and exact size designation. ACL references distinguish standard, journal-undersize, extra-clearance and housing-oversize configurations. These descriptions address different dimensions; one is not a universal substitute for another.Establish running clearance from the measured crankshaft and assembled housing/bearing with the correct tools and builder specifications. Load, oil viscosity, temperature, alignment and journal condition all matter. Neither a horsepower threshold nor a bearing brand establishes a universal tighter-clearance target.Gasket...
