Starter on a car Nissan Almera Classic is a critical component for starting the engine. In Russian winter conditions and with significant mileage, this unit often breaks down, leaving the owner in an uncomfortable position. The problem can be hidden both in the electrical part and in the mechanics of the device itself, so a superficial inspection rarely gives an accurate answer.
Common symptoms include a single click when turning the key, slow rotation of the armature, or complete lack of response to driver input. Ignoring these signs may lead to battery discharge or contact overheating, which will complicate further repairs. Qualitative diagnostics is the first step to successfully restoring your vehicle's performance.
Common causes of starter failure on Almera Classic
Understanding the nature of the fault allows you to save time and money on repairs. The most common problem is wear of the brush assembly, which over time loses contact with the armature commutator. Also often fails solenoid relay, responsible for supplying current to the traction relay and the mechanical input of the bendix.
The second most popular reason is wear of the bushings or plain bearings, which leads to armature misalignment and jamming. In such cases, when you try to start, a characteristic grinding or humming noise is heard, but the engine does not turn over. It is important to note that problems can be not only in the starter itself, but also in wiring or poor contact with the body.
- 🔋 Discharged battery or oxidized terminals, simulating a starter malfunction.
- ⚙️ Wear of the bendix (overrunning clutch) when the gear does not engage the flywheel.
- 🔌 Breakdown of insulation of armature or stator windings due to overheating.
Preparation for removal and necessary diagnostics
Before proceeding with dismantling, it is necessary to exclude external factors. Check the voltage at the battery terminals, it should be at least 12.5 Volts. Inspect the power wire running from the positive battery terminal to the starter for insulation integrity and secure fastening.
Removing the starter Nissan Almera Classic requires some access, which may be limited by attachments. In some cases, it is necessary to remove the air filter and throttle assembly. Use heads for 10, 12 and 14 mm, as well as extension cords for working in cramped conditions under the hood.
Remember safety precautions: be sure to disconnect the negative terminal of the battery before starting any work on electrical equipment. This will prevent accidental short circuits when disconnecting power wires.

Step-by-step instructions for removing the starter
The dismantling process begins with de-energizing the vehicle. Open the hood and disconnect the negative terminal. Locate the starter, which is located on the transmission housing, closer to the flywheel. Two main wires are connected to it: a thick power wire and a thin control wire from the ignition switch.
Unscrew the nut on the power wire and carefully remove it, being careful not to damage the insulation. Next, disconnect the chip from the control wire. Now you need to unscrew the mounting bolts holding the starter to the cylinder block or gearbox. Usually there are two or three of them, depending on the modification.
Remove the unit carefully, holding it as it is heavy. If it is stuck, you can carefully pry it off with a pry bar without using excessive force so as not to damage the case. Place the removed starter on a clean surface for further inspection.

Internal diagnostics and disassembly of the unit
Disassembling the starter requires care, since the pull-up relay springs are under tension. First, remove the cover from the manifold side by unscrewing the fastening nuts. Inspect the brushes: if their length is less than 5-7 mm, it is necessary replacing the brush holder or the brushes themselves.
Next, remove the solenoid relay by unscrewing the two bolts. Check its functionality by supplying power directly from the battery. If the relay clicks, but no current flows, or does not click at all, it needs to be replaced. Also check the condition of the armature windings for carbon deposits or breaks.
Pay special attention to the Bendix. Rotate its gear: it should rotate in one direction only. If the gear rotates in both directions or jams - Bendix is faulty. Also check the bushings where the armature is inserted for wear. The most common cause of starter failure on Almera Classic is wear of the bushing on the drive side, which leads to the armature being shorted to the housing.
- 🔍 Use a multimeter to check the integrity of the windings.
- 🧴 Clean the anchor collector with fine sandpaper or a rag with alcohol.
- ⚙️ Replace the bushings if they show obvious signs of wear or tearing.
Technical nuances of repair and replacement of parts
When assembling the starter, it is important to lubricate all rubbing parts with a special lubricant for starters or lithol. Do not use thin oil as it will leak and will not provide adequate protection. Pay special attention to the bushings: before installing the armature, make sure that they fit tightly and have no play.
If you are replacing a solenoid relay, make sure that the new element is completely identical to the old one in terms of contact group and pin arrangement. Sometimes you have to select relays from similar models, for example, from Nissan Primera or Renault Logan, since they have a similar design.
After assembly, check the operation of the starter “on the table” by applying power from the battery. The armature should rotate smoothly, without touching the stator, and the bendix should come out sharply and return smoothly. This guarantees successful engine starting after installation.
Why does the starter turn but not engage?
If the starter turns the engine, but it does not start, the problem may not be with the starter, but with lack of fuel, faulty spark plugs, or lack of spark. Also check the crankshaft position sensor.
Installation and performance check
Installation of a removed and repaired starter is carried out in the reverse order. Tighten the mounting bolts thoroughly to avoid vibrations that could strip the threads. Connect the power wire and control chip, making sure the contacts are secure.
Before the first start, it is recommended to double-check that all tools and parts have been removed from the engine compartment. Connect the negative terminal of the battery and try to start the engine. The sound of operation should be smooth, without extraneous noise or grinding.
If the engine starts, let the starter cool and try again in a minute. This is a check for the absence of overheating and normal operation of the cooling system of the unit. Make sure that after starting the key returns to its original position and the starter immediately turns off.
Before tightening the power terminal on the starter, sand it until it's shiny - this will ensure minimal resistance and prevent overheating during startup.
Cost of repairs and when is it better to replace the unit
Repairing a starter is often cheaper than buying a new one, especially if the problem is limited to replacing brushes or bushings. However, if the armature windings are burned out or the housing is deformed, it is more economically feasible to replace the entire assembly. Original from Nissan costs significantly more than high-quality analogues.
The average cost of repairs in the service varies depending on the complexity of dismantling and the set of necessary spare parts. If you plan to do this yourself, budget for the purchase of a repair kit: brushes, bushings, bendix and retractor relay.
| Detail | Average price (RUB) | Approximate resource (km) |
|---|---|---|
| Brush unit | 800 - 1500 | 100 000 - 150 000 |
| Solenoid relay | 1200 - 2500 | 150 000 - 200 000 |
| Bendix (overrunning clutch) | 1000 - 2000 | 120 000 - 180 000 |
| Bushing kit | 300 - 600 | 200 000+ |
If the starter starts to work unstable, do not delay repairs for a long time - this can lead to a complete stop of the car at the most inopportune moment.
Prevention and tips for extending service life
To ensure a long service life of the starter, avoid prolonged attempts to start the engine. If the car does not start the first time, take breaks of 10-15 seconds to allow the unit to cool. Prolonged idle operation overheats the windings and destroys the insulation.
Monitor the condition of the battery. Low current does not allow the Bendix to fully engage, which leads to gear impacts and rapid wear. Check the electrolyte level and battery density regularly, especially before the start of the winter season.
Periodically clean the starter housing of dirt and oil, as adhered dirt impairs heat dissipation and can cause a short circuit. Use special cleaners and do not allow moisture to get into electrical connectors.
How to extend the life of the solenoid relay?
Avoid frequent short trips that do not allow the battery to charge, as this increases the current drawn by the starter each time it is started.
How can you tell if the problem is with the starter and not the battery?
If you hear a distinct click when you turn the key, but the engine does not turn, or turns very slowly and with difficulty, the problem is most often in the starter or poor contact. If, when you turn the key, nothing happens at all (there is not even a click), and the headlights go out, most likely the battery is discharged or the terminals are oxidized.
Is it possible to start the engine with a pushrod if the starter is broken?
Yes, this is possible with a manual transmission. Shift into second or third gear, depress the clutch, ask someone to help you accelerate the car, or drive down a hill, then release the clutch quickly. The engine should start. This method will not work automatically.
Do I need to replace all the brushes at once or just the worn ones?
It is recommended to change the entire set of brushes at once, even if one of them looks normal. They wear out evenly, and one short brush can upset the balance of the entire assembly, causing sparking and rapid failure of the new set.
What should I do if the starter works but makes a grinding noise?
A grinding noise usually means that the bendix is not fully engaged with the flywheel or its teeth have worn out. Also, the reason may be a worn bushing, due to which the armature is skewed. In this case, it is necessary to replace the bendix and check the condition of the flywheel.
How long does it take to repair a starter yourself?
If you have the tools and experience, removing and installing the starter on Nissan Almera Classic takes from 1 to 2 hours. Disassembly itself, replacement of parts and assembly may take another 1-2 hours, depending on the complexity of the defect and your accuracy.
