4.3.2.2. Check

Check рачаг on existence of damages, cracks and deformation.

Check the moment of resistance to rotation of the spherical hinge.

Turn a finger of the spherical hinge on five turns.

Fig. 4.25. Check of the moment of resistance to rotation of the spherical hinge

Measure the moment of resistance to rotation, using suitable face and dinamometrichesky keys (fig. 4.25).

If the result of measurement differs from norm, replace the bottom lever assembled.

Maximum moment of resistance: 1,5 N · m.
