A force sensor (21) is put into position, either at predetermined distance from the upper face of a mobile core (18), the distance equivalent to actual travel distance of the mobile core, or directly in contact with the face of the core when it is required to adjust the spring (17) based on its force after the travel distance. The spring is installed in a reaming. An elastic split pin (22) is put into position behind the spring, that is forced more or less into the reaming of the mobile core while measuring the force generated by the spring on the sensor. The split pin is no longer forced into the core as soon as the required force is measured by the sensor. |
