DIY starter repair Volkswagen Passat B3

In detail: do-it-yourself starter repair Volkswagen Passat B3 from a real master for the site my.housecope.com.

• Disconnect the negative cable from the battery.
• Mark the location of the wires on the starter traction relay, then disconnect them.
• Raise the front of the vehicle and secure it to the stands. Since the front support is also secured with the starter bolt, support the power unit from below with a jack or winch.
• Unscrew the screws and remove the starter.
• The starter is installed in the reverse order of removal.

Provides general guidelines for disassembling a typical starter. Some minor differences may arise depending on the modification of the starter.

• After disassembling the starter, check:
- the condition of the brushes, as well as the freedom of movement of the brushes in the brush holders;
- measure the length of the brushes, and in case of wear of the brushes, install new brushes that need to be soldered into place. When soldering, make sure that the solder does not get on the braided wire, as this can prevent the brushes from moving freely in the holders;
- clamping force and position of the brush springs;
- type of collector, which should be cleaned with a cloth soaked in gasoline or trichlorethylene, and sanded with fine-grained emery paper;
- condition of self-lubricating bearing bushings; if replacement is necessary, new bushings should be immersed in engine oil (viscosity SAE 30 or 40) for at least 20 minutes before installing them in the starter;
- check the gear drive teeth and make sure that the freewheel clutch rotates in only one direction;
- check the collector diameter.
• Assembly is carried out in the reverse order of disassembly.

The main malfunctions of the starter.

If you did not find information on your car, look at the cars built on the platform of your car.
With a high degree of probability, the information on repair and maintenance will be suitable for your car as well.

Hello! If you are the owner of a 1991-1996 Volkswagen Passat, then most likely you have encountered problems related to the starter. Therefore, it will not be superfluous to read about how to independently remove the starter and repair the Volkswagen Passat starter without resorting to the services of car mechanics.

Moreover, this will save a lot of money. Starters with power from 0.9 kW to 1.7 kW are used on cars of this model. Naturally, higher power starters are installed on vehicles with a diesel engine. Image - DIY starter repair Volkswagen Passat B3

They can also be equipped with a reduction gear. And so in order to remove the starter from the car you need to:

-first of all, remove the negative terminal from the battery;
- remember the location of the wires on the solenoid relay 11 (see Fig.) Of the starter and remove them;
- Jack up the front of the car and place it on the stands;
- Support the power unit of the car with a jack so that it does not overturn, since the front support is fixed with the starter bolt;
- unscrew the starter mounting bolts and remove it. The starter is installed in the reverse order.

Place new bushings in engine oil for half an hour before installing;

- check the condition of the bendix drive teeth and the bendix itself; it should only rotate in one direction;
- check the manifold itself, it should not have visible wear of the plates. If there is wear in the form of shallow grooves, give the armature to the turner, let him grind it until the surface is leveled. The starter is assembled in the reverse order.Do not forget that in addition to mechanical damage to the stator elements, damage to the armature (rotor) and stator windings often occurs. You can read about the method for checking the anchor here.

1. When the starter is turned on, the starter motor does not work.

The cause of this malfunction of the starter may be a malfunction of the starter motor itself, the traction relay, or in the wires. To find a malfunction, first check for the presence of +12 volts at the terminal of the traction relay. If there is no voltage when the starter is turned on, then the electrical circuit (wires) are damaged. In the presence of voltage, the malfunction lies in the traction relay and the starter motor itself. If, when the starter is turned on, voltage is applied to the traction relay, but it does not work (does not click), then the retractor relay is faulty (winding breakage or short circuit to ground).

If the relay clicks, then it is possible that the powerful contacts (pyataks) are burnt out or the starter motor itself is out of order. To check the operation of the starter motor itself, apply a thick wire to the traction relay contact on the side of the electric motor with a voltage of +12 volts from the battery. The minus of the battery is not forget to connect to the starter housing. If the electric motor starts to work, then the cause of the malfunction lies in the traction relay.

In this case, the reason may be: a dead battery, too thick oil in the engine crankcase, copper-graphite starter brushes are not pressed sufficiently against the armature collector, the collector surface is worn out, starter bearings are worn out.

When the ignition key is released from the "engine start" position, the starter continues to operate.

The reason may be sticking of the contacts of the solenoid relay or the ignition lock itself is faulty (the contacts are welded). At the same time, it will not interrupt the voltage supply to the solenoid relay contact. In this case, immediately turn off the ignition and disconnect the battery. Otherwise, your starter motor may fly to pieces. Be attentive and good luck with your starter repair!
