In a method of measuring errors in the flanked surfaces of the teeth of a gearwheel, the gearwheel is mounted freely rotatable. A probe is arranged to contact the flanked surface to be measured whereby the gearwheel can rotate in response to a movement of the probe which causes relative movement of the probe over said surface in a required direction. To test the flanked surface, the probe is moved in said direction by a predetermined amount, and the resulting rotation of the gearwheel is measured. The expected amount of rotation of the gearwheel for movement of the probe can be determined for the design tooth shape. Comparison of the actual amount with the expected amount of gearwheel rotation indicates the error in the flanked surface of the tooth.
