Magic Circle – Starter Repair Consultant – Car Engine

Access to the starter is better in cross-engined cars, and in the case of long-engined engines, especially V-engines, it can be classified as a more painful installation. When installing a new one, it is worth comparing it with the old part. Photo: archive

When we call a car mechanic that there is a problem, the engine does not start, the starter does not turn, the first response from the hip that we can get is sure that there is a problem with the battery. Because often the battery is really faulty, either because it is old or because the alternator is tired and only partially charging, so there is not enough juice left to enthusiastically wind the starter motor. While gasolines are more tolerant and can start even at slow and low speeds, diesels are sensitive to this.

The solenoid is not usually refurbished, but it can be replaced again

However, if there is no indication that the battery is in poor condition, it provides plenty of power, the instrument panel lights do not dim when starting, and the forgotten ventilation fan spins, but the starter motor does not work, the circuit must be further narrowed. You have to pay attention to what the car is doing and what it is not doing and what the accompanying phenomena spice it all up with. For example, if neither the picture nor the sound to turn the key is strong, even though the battery is strong, the lights are on, or the voltage has been measured, the retraction magnet or solenoid of the starter motor may be the culprit. But of course, you may sometimes start the car and you have to not. In this case, the ignition switch should also be inspected, measured and checked for current at the starter terminals. If there is a clicking sound when you try to start (so the “magnet” pulls in), it means that the starter motor is receiving power. If you do not turn the crankshaft, you may immediately suspect faults in the starter motor, jammed rotor, worn bronze brushes, and the actual fault can only be detected by complete disassembly. It is also possible that the starter does not turn the engine at all or only with an ugly sound. It is then assumed that the bendix is ​​the goose, the function of this part is to establish the gear connection between the starter motor and the ring gear on the engine flywheel.

The refurbished part, this little gear clings to the flywheel ring gear

The bendix gear may wear out or, worse, the flywheel ring may be worn. To check these, you also need to remove the starter motor. The latter is basically a repairable part, but sometimes it is easier to replace it if you get an aftermarket so cheap. The installation of the new one is also more time-saving. But if you have time and can renew the original, it is worth saving, because bendix, solenoid, bronze brush, copper ring, all available in the common types, in addition, not expensive. Of course, the cost of entry here is offset by rising wages. Disassembled parts for common types are also available, but this should be tested and maintained before installation.

When purchasing a disassembled part, it is important to be able to identify the part by number

It is very important for the repair technician to pinpoint the fault, because although the starter motor can be bought (or refurbished) for mass models at a good price, it is labor-intensive to replace. If it turns out that the fault still exists after repair or replacement, it is quite unpleasant because, say, the ignition switch has not been checked, or an alarm installed earlier is starting to go crazy and sometimes interrupts the starter circuit. A good mechanic is worth gold.
