Trapezoid wipers <em>Nissan Almera Classic</em>: how to choose, replace and avoid breakdowns

The windshield wiper trapezoid is a unit that drivers are talking about Nissan Almera Classic (N16/B10) are remembered only when it breaks. And this happens, as a rule, at the most inopportune moment: during rain, when the brushes suddenly stop moving, or in winter, when the mechanism jams from ice. Unlike brushes or a motor, a trapezoid is mechanical lever system, which transmits movement from the electric motor to the wipers. Its breakdown paralyzes the operation of the windshield wipers, and repairs often require disassembling half of the front panel.

In this article we will look at all about the trapezoid wipers Almera Classic: from the device and signs of malfunction to step-by-step instructions for replacement. You will learn which articles are suitable for different years of manufacture (2006–2012), how to distinguish an original from a fake, and why even a new trapezoid can quickly fail. And also - unique life hacks for lubrication of a mechanism that will extend its life by 2–3 times.

Design and principle of operation of trapezium wipers

Trapezoid wipers Nissan Almera Classic is a mechanism from levers, rods and hinges, which converts the rotational movement of the electric motor into synchronous swing of the wipers. Unlike modern cars, where silent gearboxes are often used, a classic design with crank mechanism. It is reliable, but requires regular maintenance.

Basic elements of a trapezoid:

• 🔧 crank — is attached to the motor shaft and converts rotation into linear motion.
• 🔗 Rods and levers — transmit force to the wiper arms.
• ⚙️ Hinges and bushings — provide mobility of connections (a common cause of breakdowns!).
• 🛠️ Leashes - metal rods to which the brushes are attached.

On Almera Classic the trapezoid is located under the plastic trim at the base of the windshield. Access to it is difficult stove air ducts And fuse box, so to replace it you will have to dismantle part of the dashboard. The principle of operation is simple: the motor rotates the crank, which moves the levers through the rods, and they, in turn, pump the wipers. But even the slightest play in the hinges or corrosion of the rods leads to uneven operation of brushes or a complete stop.

Signs of a faulty trapezoid: when to sound the alarm

The first symptoms of problems with the trapezoid are often attributed to worn brushes or a weak motor. But if you notice at least one of these signs, most likely the mechanism is to blame:

• 🚨 The wipers move jerkily or stop in the middle of the cycle.
• 🔊 Grinding or knocking under the plastic cover near the glass (especially in the cold).
• ❄️ Jamming after spending the night at sub-zero temperatures.
• 🔄 Non-synchronous work brushes (one moves faster than the other).
• 🛑 Full stop when the engine is running (a hum is heard, but the wipers do not move).

The most dangerous situation is when the trapezoid breaks down on the road when it rains. For example, on the highway M4 Don or in a traffic jam MKAD, where visibility is critical. In 80% of cases they are to blame worn bushings or rusty rodswhich could be prevented by regular lubrication. But most owners Almera Classic They learn about the trapezoid only after it breaks.

⚠️ Attention! If the wipers start to “walk” across the glass (they don’t stop in the down position), this is a sign play in trapezoid hinges. Ignoring the problem will lead to breakage of traction or motor damage.

Articles and analogues: what to choose for Nissan Almera Classic

Original trapezoid wipers for Almera Classic (N16/B10) has article number 28550-4M000 (for models 2006–2012). However, the original is from Nissan is expensive (from 8,000 ₽), so many people choose analogues. Important: trapezoids for Almera N15 (1995–2000) don't fit — there’s a different mounting design!

Proven analogues (compatible with Almera Classic):

Brand	Article	Price, ₽	Features
Febi	28550	4 200–5 100	High-quality bushings, but requires modification of the motor mount
Ruville	62306	3 800–4 500	Easy installation, but sometimes you get defective hinges
Topran	103 506	3 500–4 000	Budget option, but lasts on average 2–3 years
Sidem	500100310	5 500–6 200	The best analogue in terms of reliability, close to the original

When choosing, pay attention to bushing material: in cheap trapezoids they are plastic and quickly fall apart. The best option is cermet bushings (have Febi And Sidem). Also check the contents: the box should contain mounting bolts, retaining rings And protective covers for hinges.

Step-by-step replacement of the windshield wiper trapezoid: instructions with photos

Replacing the trapezoid with Almera Classic takes 3-4 hours and requires patience. The main difficulty is dismantling the plastic cover under the windshield and disconnecting the air ducts. You will need:

• 🔧 Set of sockets and keys (10, 12, 14).
• 🔨 Flat screwdriver for removing clips.
• 🧴 Lubrication LIQUI MOLY LM47 or CV joint-4 for hinges.
• 📸 Phone for photographing disassembly stages.

Step-by-step algorithm:

1. Remove the wipers: unscrew the fastening nuts (key 13) and remove the leads.
2. Remove the plastic cover under the glass: carefully pry up the clips with a screwdriver (there are 8 of them!).
3. Disconnect the motor: Unscrew the 3 bolts (10mm head) and disconnect the power connector.
4. Remove the trapeze: unscrew the 4 bolts securing it to the body (12mm wrench) and pull the mechanism out through the opening.
5. Install a new trapeze, lubricating all the hinges. Reassemble in reverse order.

The most common mistake is incorrect installation of retaining rings on hinges. If they are not secured, the trapezoid will “walk” and the wipers will start hitting the edge of the glass. Also don't forget calibrate the position of the brushes: After replacement they should stop in the down position (adjustable by the nut on the crank).

⚠️ Attention! When removing the cover, do not pull it by force - wires pass under it rain sensor (if installed). Their breakage will lead to an error B2600 on the instrument panel.

Trapezoid repair: when replacement is not necessary

If the trapezoid is not completely broken, but only creaks or plays, it can be repaired. Most often problems are caused by:

• 🔩 Worn bushings (change to bronze or metal-ceramic).
• 🔗 Stretched rods (can be cooked or replaced separately).
• 🧊 Jammed hinges (cleaned and lubricated).

Needed for repairs bushing repair kit (article 28550-4M001) and lubricant. Algorithm:

1. Disassemble the trapezoid by removing the retaining rings.
2. Remove the old bushings and press in new ones (use a vice!).
3. Clean rods from rust WD-40 and apply lubricant.
4. Assemble the mechanism, check the movement for play.

The cost of repair is about 1,500 ₽ (bushings + lubricant), which is 3–5 times cheaper than a new trapezoid. However, if rods are bent or the crank is cracked, repair is useless - only replacement.

What happens if the trapezoid is not repaired?

Over time, the play in the hinges will increase, and the wipers will begin to scratch the glass. In the worst case, the rod will break off, and the brush will break through the windshield at speed (there were such cases on Almera Classic when driving on the highway).

Prevention: how to extend the life of the windshield wiper trapezoid

Service life of trapezoid Almera Classic — 5–7 years with proper care. But for most owners it lasts no more than 3–4 years due to lack of prevention. Here's what to do:

• 🌡️ in winter: before frosts, lubricate the hinges silicone grease (doesn't freeze!).
• 🚿 Summer: Wash the mechanism from dirt (especially after off-road trips).
• 🔧 Once a year: check the play in the leads and tighten the fastenings.
• ❄️ In the cold: Do not turn on the wipers if they are frozen to the glass - warm them up first.

A unique life hack: before winter, apply a mixture of 70% to the hinges of the trapezoid LIQUI MOLY LM47 and 30% graphite grease. This combination does not thicken in the cold and protects against corrosion 2 times more effectively than standard lubricants.

Also avoid cheap brushes with a metal frame - they create additional load on the trapezius. The best choice for Almera Classic: frameless brushes Bosch Aerotwin or Denso.

Common replacement mistakes and how to avoid them

Even experienced craftsmen make mistakes when working with a trapezoid. Almera Classic. Here are the most common:

• 🔧 Incorrect bolt tightening - leads to skew of the trapezoid and beating of the brushes.
• 🔌 Confusion with motor connector - on Almera Classic it is polar, and if you turn it upside down, the wipers will work in the opposite direction.
• 🧩 Lost circlips — without them, the hinges will become loose within a month.
• 📏 Uncalibrated brushes — if you do not adjust the lower position, they will stop in the middle of the glass.

To avoid problems, follow two rules:

1. Take photographs of each stage of disassembly (especially the location of the wires!).
2. Check the operation of the wipers before final assembly - it’s easier to correct mistakes this way.

⚠️ Attention! On Almera Classic with air conditioning When replacing the trapezoid it is easy to damage evaporator radiator. It's located to the right of the wiper mechanism - be careful with the tools!

FAQ: answers to frequently asked questions

Is it possible to drive without a wiper blade if it is broken?

Technically yes, but this dangerous and illegal. According to the traffic rules (clause 4.1), faulty windshield wipers are grounds for a fine (500 ₽) or a ban on operation. In addition, without wipers, you run the risk of losing control in the rain.

How much does it cost to replace a trapezoid at a service?

At official dealers Nissan the work will cost 6,000–8,000 ₽ (plus the cost of spare parts). In independent services - 3,000–4,500 rubles. Replacing it yourself will save up to 50% of your budget.

Why did the new trapezoid break so quickly?

Most often the culprits are: 1) poor quality bushings (in cheap analogues), 2) lack of lubrication during installation, 3) overload due to heavy brushes or freezing. Check also wiper motor - if he works with jerks, this will accelerate the wear of the trapezoid.

Is the trapezoid suitable for Nissan Note or Micra?

No! These models have a different mounting design and rod length. The only compatible analogue is the trapezoid from Renault Samsung SM3 (article 28550-4M000, the same one).

How to check a trapezoid before purchasing?

Inspect: 1) play in the hinges (there should be no gaps), 2) integrity of rods (no cracks or rust), 3) completeness (all fasteners must be present). Also shake the mechanism - there should be no rattling sounds (a sign of weak bushings).
