Starter
The system includes the electric start engine battery, a starter, the traction relay, ignition switch, starter lock switch (only on cars with automatic transmission), connecting wires and battery cables. When you turn the ignition switch to start the motor current of the battery is supplied to the winding of the traction relay of a starter. Thus there is a shift of the anchor of the traction relay and the actuator arm of the overrunning clutch, the gear drive is engaged with the flywheel. Contacts are closed and the starter motor is activated. Have overrunning clutch protects the armature winding and the collector of the span.
Adjusting the gap between the end of the drive gears and focus
| Fig. 7.16. Wiring the battery when adjusting the gap between the end of the drive gears and focus: 1 - the switch; 2 - wire field winding; 3 - starter
|
Wiring the battery when adjusting the gap between the end of the drive gear and an emphasis is shown in Fig. 7.16. Disconnect the field winding from terminal "M" pulling the relay. Connect the 12-volt battery to the terminals ?�S?� and ?�M?�. Gear drive should move to a position of engagement.
A WARNING To prevent coil, perform the test as soon as possible (within a maximum of 10). |
With the probe, check the clearance between the end of the pinion drive and focus.
| Fig. 7.17. The gap between the end of the drive gears and focus: 1 - an emphasis; 2 - the gap between the end of the drive gears and focus; 3 - gear
|
The gap between the end of the drive gear and an emphasis should be 0.5-2.0 mm (Fig. 7.17). If the armature shaft endplay does not fit within these limits, adjust it by installing or removing shims between the traction relay and the cover on the drive side.
Checking the technical condition of the starter Checking the pull-in winding traction relay
| Fig. 7.18. Wiring the battery when testing pull-winding of the traction relay of a starter: 1 - the storage battery; 2 - starter
|
Wiring the battery when checking retraction pulling the starter relay coil is shown in Fig. 7.18. Disconnect the field winding from terminal "M" pulling the relay. Connect the 12-volt battery to the terminals ?�S?� and ?�M?�.
A WARNING To prevent coil, it checks as quickly as possible (within a maximum of 10). |
If the drive gear is shifted to a position of engagement, which draws relay coil is working. If it does not, replace magnetic switch. Check keeping winding of the traction relay
| Fig. 7.19. Wiring the battery when checking keeping winding of the traction relay of a starter: 1 - the storage battery; 2 - starter; 3 - wire field winding
|
Wiring the battery when checking keeping winding of the traction relay of a starter shown in Fig. 7.19. Disconnect the field winding from terminal "M" pulling the relay. Connect the 12-volt battery to a conclusion ?�S?� and "weight."
A WARNING To prevent coil, perform the test as soon as possible (within a maximum of 10). |
If the drive gear is put forward in the engaged position, the relay correctly. If the gear repeatedly extends and returns to its original position, so there was breakage in the holding coil. Replace magnetic switch. Check idling
| Fig. 7.20. Wiring the battery when checking the starter idle 1 - starter; 2 - carbon resistor; 3 - Ammeter; 4 - voltmeter; 5 - battery
|
Wiring the battery when checking starter idling is shown in Fig. 7.20. Hold the starter in a vice with the jaws of a soft material and connect a fully charged 12-volt battery to the starter as shown in the figure. Connect a test ammeter (with a scale of 100 A) and the carbon resistor. Connect a voltmeter (with the scale to 15) parallel to the starter. Install a carbon resistor in the off position. Attach a wire from the negative terminal of the battery to the starter. Rheostat set on voltmeter 11 V. Include a starter and check that the maximum rate of current consumption, as well as smooth and ease of rotation of the armature of a starter. The strength of the current consumption must not exceed 90 A, speed anchors - not less than 2800 min -1. Check of the traction relay is released
| Fig. 7.21. Wiring the battery when checking releasing pulling the starter relay: 1 - the storage battery; 2 - starter; 3 - wire field winding
|
Wiring the battery when checking releasing pulling the starter relay is shown in Fig. 7.21. Disconnect the field winding from terminal "M" pulling the relay. Connect the 12-volt battery to a conclusion "M" and "weight".
A WARNING To prevent coil, perform the test as soon as possible (within a maximum of 10). |
Pull and push the drive gear. If pinion quickly returns to its original position, the traction relay correctly. Otherwise, replace the traction relay.
Removing and installing starter
| Fig. 7.22. Starter: 1 - the screw; 2 - a cover from outside a drive; 3 - a lock ring; 4 - thrust ring; 5 - way clutch; 6 - ring gear; 7 - the sun gear; 8 - the traction relay; 9 - satellites; 10 - ball; 11 - holder; 12 - stator; 13 - anchor; 14 - brush holder; 15 - a cover from outside a collector; 16 - a coupling bolt
|
| Fig. 7.23. Attaching to the starter clutch housing
|
The starter is shown in Fig. 7.22. Attaching to the starter clutch housing shown in Fig. 7.23. Disconnect a wire from "the minus" plug of the storage battery. Disconnect from a transmission flexible shaft drive speedometer cable and the drive gear. Disconnect the connector from the starter and the tip of the wire. Remove the starter by removing the two screws securing it. Installation is carried out in reverse order.
Technical condition Check collector
| Fig. 7.24. Check heartbeat collector prisms
|
Set anchor in two prisms with a dial gauge, check the beating of the collector (Fig. 7.24). Rated beating collector 0.05 mm. Maximum permissible palpation reservoir 0.1 mm.
| Fig. 7.25. Checking the wear of the collector
|
The nominal diameter of 29.4 mm collector. Maximum permissible diameter of 28.4 mm collector.
| Fig. 7.26. Check the depth of the grooves between the collector plates: 1 - plate collector; 2 - the depth of the groove
|
Check the depth of the grooves between the collector plates (Fig. 7.26). The nominal depth of the grooves between the collector plates 0.5 mm. Maximum allowable depth of the grooves between the collector plates 0.2 mm.
Check the brush holder
| Fig. 7.27. Check the brush holder for a short
|
Check the insulation between the base plate and the brush holder (Fig. 7.27).
Checking freewheel Holding the hand freewheel body, rotate the drive gear. Pinion should rotate smoothly in one direction and does not rotate in the opposite direction. If the clutch is not working properly, replace it. Check the pinion for wear or burrs on the teeth. In the presence of wear or scoring, replace overrunning clutch assembly. If damaged, check the gear drive and the flywheel for wear or burrs on the teeth.
Check plugs lids on the drive side and the collector Check the sleeve for wear or scoring on the friction surfaces. If any are found, replace the cover on the drive side or collector.
Cleaning parts starter Do not wash the parts by immersion in a solvent, as this will damage the stator winding of the traction relay, and / or Anchor. These parts should only be cleaned by wiping with a cloth. Do not immerse in solvent is the starter motor. The solvent will wash lubrication built into the freewheel during assembly. Clean the drive brush moistened with solvent, and then wipe with a cloth.
Brush replacement brushes and springs Replace worn or oily brushes. When replacing the brushes field winding break the worn brush with forceps, taking care not to damage the wire brush. Strip the end of the wire brush sandpaper to ensure reliable soldering. Insert the wire brush into the opening of a new brush and solder it. Make sure that the wire does not protrude on the surface of the brush was no excess solder. When replacing the "negative" of the brush remove the brush from brush holder by releasing the retaining spring.
