Nissan Almera N16 (2000-2006) is a reliable car, but even it has critical parts that wear out over time. One of these is starter brushes, which ensure the transmission of current to the rotor. Their malfunction leads to problems with starting the engine, especially in the cold season. In this article we will look at how to recognize brush wear in time, select high-quality analogues and replace them yourself - without contacting service.

Owners Almera N16 Often they are faced with the fact that the starter does not start to “catch” the first time or makes strange sounds. In 80% of cases, it is the brushes that are to blame - they wear out, jam, or lose contact. At the same time, many car owners mistakenly blame the battery or solenoid relay. We will help you avoid common mistakes and save on diagnostics.

Signs of wear on the starter brushes Nissan Almera N16

The first symptoms of brush problems are often confused with a low battery or a faulty solenoid relay. However there is characteristic features, which directly point to the brush assembly:

  • 🔋 Starter doesn't turn the first time, but after 2-3 attempts the engine starts. This is due to the fact that worn brushes do not provide stable contact.
  • 🔊 Appears grinding or crackling when trying to start - a sign that the brushes are “slipping” along the rotor commutator.
  • 🔥 Burning smell from under the hood after long attempts to start. Not only the brushes overheat, but also the starter winding.
  • 🚗 The starter works “in jerks” - it turns and then stops. This speaks of uneven wear of the brushes or their jamming in the guides.

If you notice at least 2-3 symptoms from the list, the probability of brush wear exceeds 90%. On Almera N16 with engines QG15DE And QG18DE the problem manifests itself in the same way, but on engines with high mileage (200+ thousand km), the brushes wear out faster due to the increased load.

⚠️ Attention: Don't ignore the grinding noise when starting up! If the brushes are completely worn out, the starter rotor will begin to scratch the commutator, which will lead to the need to replace the entire assembly (cost - from 8,000 ₽).

Original articles and analogues of starter brushes

On Nissan Almera N16 Two types of starters were installed: Mitsubishi (article M000T27881) and Denso (article 28000-4M000). The brushes for them are interchangeable, but have different catalog numbers. Below is a table with original parts and proven analogues:

Starter type Original article number of brushes Analogs (brand + article) Average price, ₽
Mitsubishi 28500-4M000
  • Bosch 1 987 432 015
  • Valeo 438036
 1 200–1 800
Denso 28000-4M010
  • Blue Print ADG02401
  • Febi 23610
 900–1 500
Universal (suitable for both types) —
  • NGK B8ES (set of 4 pieces)
  • Beru GE144
 600–1 000

When choosing analogues, pay attention to brush material:

  • 🔹 Copper-graphite - cheaper, but wear out faster (resource ~50 thousand km).
  • 🔹 Carbon-graphite - more expensive, but last 1.5–2 times longer (resource ~100 thousand km).

On Almera N16 With a mileage of over 150 thousand km, we recommend taking carbon-graphite brushes - they better withstand high loads.

Diagnostics of starter brushes without removing the unit

Before disassembling the starter, you can check the brushes without dismantlingusing a multimeter and visual inspection. Here are the step-by-step instructions:

  1. Checking the voltage at the starter:
    • 🔧Connect red multimeter probe to the positive terminal of the starter.
    • 🔧 Black probe - for ground (for example, for the engine housing).
    • 🔋 When you turn the ignition key, the voltage should be 12–14 V. If less, the problem is in the wiring or battery.
  2. Checking for spark:
    • 🔦 Remove the starter protective cover (if equipped).
    • 🔦 Ask an assistant to turn the ignition key while you watch the starter in the dark.
    • ⚡ If visible sparks or arc — brushes are worn out or dirty.

Also note rotor commutator condition (visible through the hole in the starter housing). If it has deep furrows or soot, brushes must be changed without fail - even if they have not yet been completely worn out.

⚠️ Attention: Do not check the starter “for spark” for more than 3-5 seconds! This can lead to melting of the rotor winding.
💡

If during diagnostics you find that the brushes are “stuck” in the guides, do not try to clean them with sandpaper - this is a temporary solution. It is better to replace the brush assembly completely, since graphite dust has already entered the mechanism.

Step-by-step replacement of starter brushes with Nissan Almera N16

To replace the brushes you will need to remove the starter. On Almera N16 it takes ~1 hour. We will break the process into stages with photo explanations (if there were any) and key nuances.

1. Removing the starter

  • ⚠ Disable negative battery terminal (required!).
  • 🔧 Unscrew 3 starter mounting bolts (two on top, one on bottom). On the engine QG18DE The bottom bolt may be hidden by protection - it will have to be removed.
  • 🔌 Disconnect power wire (thick red) and control wire (thin, from the solenoid relay).

2. Disassembling the starter and replacing brushes

-->

Disassembly algorithm:

  1. Remove protective cover starter (usually secured with 2 screws).
  2. Unsolder or disconnect brush wires from the board (remember their location!).
  3. Remove old brushes and clean brush assembly from graphite dust (use compressed air or brush).
  4. Install new brushes after lubricating the guides thin layer of LIQUI MOLY.
  5. Check rotor play - if it is more than 0.5 mm, the bushings will need to be replaced.

When assembling, make sure that the brushes walk freely in the guides, but do not dangle. If they move too tightly, sand them down to width using fine sandpaper (grit P1000).

⚠️ Attention: Do not use WD-40 to clean the brush assembly! It leaves an oil film that impairs contact. Better take it CRC Brake Cleaner.

3. Starter installation and check

After assembly:

  1. Reinstall the starter by tightening the bolts firmly. 25–30 Nm.
  2. Connect the terminals (first the control wire, then the power wire).
  3. Check operation: the starter should turn the engine smoothly, without jerking.

💡

If, after replacing the brushes, the starter still works intermittently, check the solenoid relay and bendix - their malfunction gives similar symptoms.

Typical mistakes when replacing brushes

Even experienced car owners make mistakes that lead to repeated disassembly of the starter. Here are the most common:

  • 🔧 Incorrect soldering of wires - if the polarity is reversed, the brushes will spark and quickly burn out.
  • 🛠 Using poor quality lubricant — lithol or grease harden at low temperatures, blocking the movement of the brushes.
  • 🔍 Ignoring collector status - if there are grooves on it, the new brushes will wear off in 10-20 thousand km.
  • 🔋 Checking the starter without load — on the table it can work perfectly, but under load (when starting the engine) there will be drawdowns.

To avoid problems, after replacing the brushes required:

  • 🔹 Check battery voltage (must be at least 12.6 V).
  • 🔹 Warm up the engine and try to start it 3–5 times in a row - this way you will be convinced of the stability of work.

What should I do if, after replacing the brushes, the starter turns slowly?

If the starter turns slower than before replacement, check:

1. **Contact quality** on the power wire (the terminal may have oxidized).

2. **Resistance of the windings** of the rotor and stator (should be in the range of 0.1–0.5 Ohm).

3. **Battery charge** - even new brushes will not save you if the battery is discharged.

If the problem persists, the starter bushings may be worn out or the windings may be damaged.

Brush life and maintenance

Starter brush life Nissan Almera N16 depends on several factors:

  • 🔹 Material — carbon-graphite ones last longer than copper-graphite ones.
  • 🔹 Riding style — frequent short trips with cold starts reduce the resource.
  • 🔹 Electrical quality — voltage surges (for example, when “lighting up”) accelerate wear.

Average service life:

  • 🔋 Original brushes - 80–120 thousand km.
  • 🔋 High-quality analogues (Bosch, Valeo) — 60–100 thousand km.
  • 🔋 Universal brushes - 30–50 thousand km.

To extend the life of your brushes:

  1. 🔧 Clean regularly (every 20 thousand km) battery terminals And starter contacts from oxidation.
  2. 🔋 Avoid holding the key for a long time in the “start” position (more than 5 seconds).
  3. 🛠 Check once every 50 thousand km rotor play and condition of the bushings.

If you often drive off-road or in high humidity conditions, treat the starter contacts protective spray (For example, CRC 2-26). This will prevent corrosion and improve conductivity.

FAQ: Frequently asked questions about starter brushes Nissan Almera N16

Is it possible to restore starter brushes without buying new ones?

Theoretically, yes - if the brushes are not completely worn out, they can be sharpened and new contacts can be soldered. However, this is a temporary solution: restored brushes will last no more than 10–15 thousand km. In addition, when soldering there is a risk of damaging the insulation of the windings. We recommend replacing the brushes with new ones. — their cost (from 600 ₽) is incommensurate with the risks.

How to distinguish brush wear from a malfunction of the solenoid relay?

If you have problems with solenoid relay the starter either does not respond to turning the key or emits single click without rotation. If the starter turns intermittently or grinds, the brushes are to blame. You can also check the relay by applying +12 V directly to its control contact - if the starter starts working, the relay is faulty.

Do I need to change starter bushings when replacing brushes?

Not always. Bushings (sliding bearings) are changed if:

  • 🔹 The rotor has backlash more than 0.5 mm.
  • 🔹 Visible on the bushings scuffing or wear.
  • 🔹 Starter gets hot and slows down when rotating.

On Almera N16 Bushings last ~150–200 thousand km, so when driving up to 100 thousand km, they are usually not required to be replaced.

Which brushes are better - original or analogues?

Original brushes (Nissan/Mitsubishi) are optimal in terms of price/quality ratio, but they are difficult to find in retail. Among analogues, the best options are:

  • 🥇 Bosch 1 987 432 015 — carbon-graphite, resource ~100 thousand km.
  • 🥈 Valeo 438036 - a good alternative to the original, but a little softer.
  • 🥉 NGK B8ES — a budget option for universal starters.

Avoid cheap, unbranded Chinese brushes - they often have incorrect hardness and erase the collector.

Is it possible to drive with worn starter brushes?

Technically yes, but it is fraught:

  • ⚡ By fire — sparks from poor contact can ignite graphite dust.
  • 🔧 Starter failure - if the brushes are completely worn out, the rotor will lock.
  • 🔋 Low battery - the starter will consume more current.
The maximum “safe” mileage with worn brushes is 500–1000 km. After this, the risk of breakdown increases sharply.
