7.3.3. Adjustment of an axial gap of the leading gear wheel

Disconnect a stator winding wire from a conclusion of "M" of the traction relay.

Fig. 7.56. Scheme of adjustment of an axial gap of the leading gear wheel


Connect wires from plugs of 12 V of the rechargeable battery (via the switch) to conclusions of "S" (+) and "M" (–) the traction relay (fig. 7.56).
Install the switch in situation "Incl.", at the same time the leading gear wheel of a starter will be pushed forward against the stop.

ATTENTION
It is necessary to make this check quickly, no more than 10 with, for prevention of burn-out of a winding of a starter.


Fig. 7.57. Check of an axial gap of the leading gear wheel


By means of the probe measure an axial gap between the leading gear wheel and a restrictive ring. If the axial gap does not correspond to the range of nominal rates, then adjust it by installation or removal of adjusting laying between the traction relay and a forward arm of a starter (fig. 7.57).
Nominal gap: 0,5–2,0 mm.
