5.2.2. Check of the moment of the beginning of a provorachivaniye of the spherical hinge of a tip of steering draft

ATTENTION Do not turn on a nut of a tip of steering draft from the spherical hinge. Weaken it when using the special tool in order to avoid possible damage of a carving of the spherical hinge.

Suspend the special tool by means of a cord in order to avoid its falling.

Establish a sjnemnik of the spherical hinge (МВ991897) how it is shown in drawing.

After installation of tightening plates of the special tool in parallel each other by rotation of a bolt and the adjustment handle, tighten a bolt a hand and be finally convinced in volume, tightening plates are located in parallel each other.

NOTE At installation of tightening plates in parallel, be convinced that the handle of the tool is in the situation shown in drawing.

Tighten a tool bolt a key that the tip of steering draft was disconnected.

Undertake a hand a carving part of a hairpin of the spherical hinge, several times turn the hinge, then screw a nut on its carving part. By means of a dinamometrichesky key (МВ990326), measure the moment of the beginning of a provorachivaniye of the spherical hinge.

Nominal rate: 0,5–2,5 N · m.

If the measured value of the moment surpasses nominal rate, replace a tip of steering draft.

If the measured size less nominal rate, be convinced that the spherical hinge is turned freely, without considerable люфта and jammings. In the absence of axial люфта or jammings, the spherical hinge is suitable for a reuse.

ATTENTION Thus it is necessary to change each time a nut of the spherical hinge on new as this nut is самоконтрящейся.

Connect a tip of steering draft to a rotary fist, tighten connection самоконтрящейся a nut the nominal moment.

Nominal moment of an inhaling: 25 + 5 N · m.
