The starter bushing is required to power the armature. It is through the bushing that the minus is fed to the rotor winding, plus it is fed using the brush assembly. When the sleeve is destroyed, contact is lost, as a result of which the starter works unstable.
Necessary
- - a set of cap and socket wrenches;
- - flat and Phillips screwdrivers;
- - new bushing;
- - fine-grained sandpaper.
Instructions
Step 1
Prepare your vehicle for repairs. Remove the negative terminal from the battery to eliminate the possibility of a short circuit. When repairing electrical equipment, always try to de-energize the vehicle. If the VAZ-2109 car is carbureted, then you do not need to remove any nodes. But if the nine is injector, then you will have to remove the air filter, since it will interfere with the dismantling of the starter. You can remove the crankcase protection to remove the starter from the bottom later.
Step 2
Unscrew the power cable that fits to the starter solenoid relay. This is done with a key of 13. Then remove the second wire, thin, which also goes to the retracting one. A thin wire supplies power to the relay coil when the ignition key is turned. Now remove the three nuts that secure the starter to the clutch block. That's it, you can remove the starter and repair it.
Step 3
Unscrew the nut with a 13 key, which secures the wire from the starter to the solenoid relay. Only then can you use a Phillips screwdriver to unscrew the bolts that secure the retractor relay to the starter housing. Set the relay aside along with the core. Now you need to disassemble the starter itself in order to change the bushing on the back cover. On some models of starters, bushings were also installed on the front cover, which is part of the clutch block. But for some time now they began to use starters with a planetary gear, so the need for a second sleeve simply disappeared by itself.
Step 4
Remove the two bolts that secure the protective cap that covers the motor shaft. On the shaft you will see a retainer that must be removed for further disassembly. Now unscrew the two nuts from the studs and remove the back cover. Now you can start removing the old bushing and installing the new one. Use a punch or a piece of pipe of a suitable diameter to knock out the old bushing. Carefully so as not to damage the lid body. Otherwise, you will have to change the entire starter.
Step 5
Press in the new bushing using the same tube or old bushing. The second option is preferable, since the bushing is made on the basis of soft metal, so it will absorb impact, so the back cover will not suffer. Before pressing in a new sleeve with fine-grained emery paper, lightly sand the seat, get rid of dirt on the surface of the cover. This will only improve contact and make the electric starter easier to operate.
