Fig. 4.24. Check of the moment of resistance to rotation of the spherical hinge
|
Measure the moment of resistance to rotation, using the suitable face and dynamometer keys (fig. 4.24).
If the result of measurement differs from norm, replace the lower lever assembled.
Maximum moment of resistance: 1,5 N · m.
