1. To examine the starter case, to remove dirt and copper-graphite dust from an internal surface. |
2. To check a condition of isolation of coils of a winding of excitement, and also lack in them of breaks and short circuits. |
3. To make removal and replacement of faulty coils of a winding of excitement in the following order: – to unscrew four polar screws by means of the press screw-driver and to take out poles, previously having noted on poles and the case of the place of their arrangement; – to take out excitement coils from the case. |
4. Installation of new coils of excitement needs to be made upside-down taking into account the following: – to lower polar screws before installation in natural drying oil; – to establish poles with coils strictly on tags and, having parted them on diameter, to fix by polar screws; – to establish and fuller screws on a vent after their inhaling |
5. To check a condition of brushes and ease of their movement in brush holders. To replace the brushes having height of 6-7 mm. |
6. To examine and check a condition of a winding of an anchor and a working surface of a collector: – to clear the polluted collector a glass skin granularity 80 or 100 then to blow a starter compressed air; – at a considerable roughness of a collector and a vystupaniya of mica between its plates to pierce a collector on the turning or special machine; – after a pro-point to smooth out a collector surface a glass skin granularity 80 or 100; – not to cut mica between plates of a collector of a starter as copper brush dust with dirt will jam into flutes that can break normal work of a starter; – the collector beating in relation to pins of a shaft should not exceed 0,05 mm, and purity of processing of a surface has to be not less class Ra of-1,25 microns. |
7. To check effort of pressing of brushes springs. Effort of pressing of brushes to check a dynamometer. It has to be in limits 10 – 14 N (1,0 - 1,4 kgfs). To make adjustment twisting or untwisting of a spring. The increased effort results in premature wear of brushes, and lowered – to lag of brushes and loss of power of a starter.
|
8. To check a condition of contacts of the traction relay of a starter. At a considerable podgar of contacts to smooth out them a small glass skin. At wear in the place of contact with a contact disk to develop contacts on 180 °. |
9. To examine the drive and in the presence забоин on a zakhodny part of teeths of a gear wheel to polish them a thin emery circle of small diameter. |
