The flywheels are for use on reciprocating internal combustion engines in conjunction with flywheel housings and clutch housings which are dealt with in IsO 7648[1] and ISO 7649[2]. Dimensions and tolerances not specified are left to the discretion of the component manufacturer. ThisInternationalStandardappliestoreciprocatinginternal combustionengines,withtheexceptionof enginesfor aircraft and passenger cars; it may be used for other engine applications where no specific International Standard exists.
