Pic. 7.56. Scheme for adjusting the axial clearance of the drive gear
Connect the wires from the 12V battery terminals (through the switch) to conclusions «S» (+) And «M» (–) traction relay (pic. 7.56).
Set the switch to position «On», while the starter drive gear will move forward until it stops.
Attention! This check must be carried out quickly, no more than 10 s, to prevent burnout of the starter winding.
Pic. 7.57. Checking the axial clearance of the drive gear
Using a feeler gauge, measure the axial clearance between the pinion gear and the restrictor ring. If the axial clearance does not correspond to the range of nominal values, then adjust it by installing or removing shims between the traction relay and the starter front bracket (pic. 7.57).
Nominal clearance: 0.5–2.0 mm.
