The following torque specifications apply to all Classic Mini A-Series engines (848cc, 998cc, 1071cc and 1275cc) unless otherwise noted. Always use a calibrated torque wrench and refer to your workshop manual for engine-specific variations. Torque figures are given for clean, dry threads — reduce by 10–15% for lubricated threads.
