Check of an axial backlash of a gear wheel


Check

After dismantle from the starter engine it is necessary to check up freedom of moving of a gear wheel on screw cutting of a shaft and freedom of rotation of a shaft of the electric motor (by means of a screw-driver).

If a shaft заедает, it is necessary to disassemble a starter at once. In case of normal rotation of a shaft it is necessary to check up at first a starter idling, and then if necessary to disassemble.

To collect the electric scheme for the starter check, shown on drawing Dismantling, check and starter assemblage. To include a starter and to measure a consumed current, pressure and frequency of rotation of a shaft of the electric motor. To compare the received values to the nominal.

If rating values are given without a current consumed by the traction relay, it is necessary to correct results of measurements, having subtracted from the received value the rated current consumed by the keeping winding of the relay.

To switch off a food and to disassemble the electric scheme.

1. If the consumed current and frequency of rotation of a shaft of the electric motor correspond to rating values, the starter is serviceable.

2. Low speed of rotation of a shaft and the big consumed current are signs of following malfunctions:

– The increased resistance to rotation of a shaft because of the big tightness, deterioration or pollution of bearings, a bend of an anchor of the engine etc.;
– Short circuit of windings of an anchor;
– Short circuit of windings of an anchor or excitation windings.

3. If the shaft does not rotate at the big consumed current, the possible reasons are:

– Short circuit on weight in a winding of excitation or on plugs;
– Jamming of bearings. (It is necessary to check up, rotating an anchor by hand). To disassemble a starter.

4. If the shaft does not rotate in the absence of a current in a chain, the possible reasons are:

– Rupture in an excitation winding. To disassemble a starter and to check up internal switching and integrity of windings by means of a control lamp;
– Rupture in an anchor winding. To disassemble a starter and to examine an anchor;
– Breakage of a spring of a brush, deterioration of brushes, pollution of plates of a collector and other reasons worsening contact of brushes with plates of a collector. To disassemble a starter.

5. Low speed of rotation of a shaft at a small consumed current:

– The increased internal resistance because of bad contact, malfunction of wires, pollution of plates of a collector and other reasons. To disassemble a starter.

6. High speed of rotation of idling at the big consumed current testifies usually to short circuit in an excitation winding. To disassemble a starter and to check up excitation windings статора.

Dismantling

PERFORMANCE ORDER

1. To turn away screws of fastening of plugs and the traction relay. To turn the relay case on 90 degrees and to remove together with an anchor and a spring. To check up and repair the relay. 2. To turn out two coupling bolts, to remove a back cover and a washer. (On a starter for the car with the diesel engine to remove in addition изоляционную a lining). 3. To disconnect the case статора from a forward cover. (On a starter for the diesel car the electric motor anchor remains in a forward cover). Operation is carried out only on the starters intended for diesel cars. 4. To take out an axis вильчатого the lever. Operation is carried out only on the starters intended for diesel cars. 5. To take out an anchor of the electric motor from the plug of a forward cover. After that the lever and a relay anchor freely act in film (fig. the Lever of a drive and an anchor of the traction relay) see. 6. If necessary to dismantle МСХ from an anchor shaft to execute following operations (fig. of the Gear wheel and муфта a free wheeling see): 6а. To remove a persistent washer. 6б. To put on a shaft and to rest against the plug 4 long tip in diameter about 16 mm or a piece of a suitable tube. Easy blow on a tube to remove the plug from a spring ring. 6в. To take out from a flute on a shaft a spring ring. If the ring was deformed, it is necessary to replace it new (at the subsequent assemblage). 6г. To remove from a shaft of an anchor the plug and МСХ. (On статоре for the diesel car in addition to dismantle from a shaft a fibre washer and the average bearing). 7. To take out a finger and to remove the lever of a drive and a relay anchor. 8. If necessary to dismantle щеткодержатель on a standard starter to execute following operations (fig. Replacement щеткодержателя, a standard starter see): 8а. To take out an axis щеткодержателя. 8б. To remove a spring щеткодержателя. 8в. To replace in need of a brush. 9. If necessary to dismantle щеткодержатель on a starter 5МТ to execute following operations (fig. Replacement щеткодержателя, a starter 5МТ smaller capacity see): 9а. To remove щеткодержатель from an arm 9б. To turn out the screw from щеткодержателя and to remove a brush 9в. To check up serviceability щеткодержателя, absence of defects or deterioration. 9г. If necessary to replace brushes and-or щеткодержатели.

Assemblage

PERFORMANCE ORDER

1. To establish on anchor МСХ with a gear wheel: 1а. To grease the end of a shaft of an anchor with greasing 1960954 or similar. 1б. To establish on a shaft the average bearing (starters for diesel cars). The bearing should be turned to an anchor winding. Then to establish on a shaft a fibre washer. 1в. To put on shaft МСХ with a gear wheel. The gear wheel should settle down more close by the shaft end. 1г. To establish on a shaft of an anchor the plug. Проточка plugs should be turned by the shaft end. 1д. To establish in a flute of a shaft of an anchor a spring ring. 1е. To establish a persistent washer on a shaft. 1ж. To arrange the plug and a persistent washer on the different parties from a spring ring. By means of two flat-nose pliers to compress the plug and a spring ring and запрессовать a spring ring in the plug. The plug should be reliably fixed in an axial direction on an anchor shaft. 2. To grease the plug of a forward cover of a starter with greasing 1960954 or similar. 3. To insert the end of the lever of a drive in ring проточку plugs MSH and to establish МСХ in a forward cover of a starter. On starters for cars with petrol engines the drive lever can be established preliminary. 4. To insert an axis of the lever of a drive and to fix it. 5. To establish the traction relay in gathering and a lever finger. 6. To put a layer of hermetic N 1050026 or similar structure on the interfaced plane of the relay contacting to the case статора. 7. To attach the case статора to a forward cover, having established it on directing pin. To show care, not to damage a brush. 8. To grease the plug of a back cover of a starter with greasing 1960954 or similar. 9. To establish on the back end of a shaft of an anchor a washer, to put on a back cover, to establish and tighten coupling bolts in through apertures. On starters for diesel cars before installation of a back cover it is necessary to establish isolating lining. At installation of coupling bolts to track that they have passed through apertures in a lining. 10. To attach winding wires статора to conclusions of the traction relay. At assemblage of a starter or after replacement of the traction relay it is necessary to check up an axial backlash of a gear wheel. The correct backlash of a gear wheel is necessary for an exception of a friction of a plug of the lever about plug MSH at work of the electric motor of a starter. 11. To disconnect a winding wire статора from the plug of the traction relay and properly to isolate a wire. 12. To connect one wire from аккумуля the even battery to the plug of a winding of the traction relay, and another — to статору. 13. To connect for short time by means of a lengthening wire the plug of the traction relay with статором. Thus the gear wheel should be pushed forward into position and remain in this position before battery switching-off. 14. To move a gear wheel back, completely having chosen an axial backlash. To measure an axial backlash of a gear wheel by means of flat щупа. The axial backlash of a gear wheel should be in limits of 0,25-3,5 mm. In a starter design it is not provided means of adjustment of an axial backlash of a gear wheel. If the backlash falls outside the limits an admissible range, to check up correctness of assemblage of a starter and to replace the worn out details.
