Nissan Almera G15 is a popular sedan with a manual transmission, where the clutch plays a key role in a comfortable ride. Over time, the pedal may “go” to the floor, slipping or jerking may occur when starting. These are signals that it’s time to start making adjustments. In 80% of cases, the problem is solved by adjusting the cable or pedal free play - without replacing components.
In this article we will look at how to properly adjust the clutch on Almera G15 (2013–2018) with mechanics, without resorting to the help of a service station. We will describe step-by-step actions, indicate acceptable gaps and warn against common mistakes. The material is suitable for both novice car owners and those who have already encountered repairs. transmissions.
Signs of clutch failure Nissan Almera G15
The first “bells” about problems with the clutch are often ignored, attributed to “car features”. However, delay leads to wear on the basket, disc and flywheel - and this is an expensive repair. Pay attention to the following symptoms:
- 🚗 The clutch pedal “fails” or is too tight - it requires an unusually large force to press.
- 🔥 The smell of burning during a sharp start is a sign of slipping driven disk.
- 🔄 Jerks when changing gears, especially when cold.
- 🛑 The car does not move when the pedal is released (the clutch “drives”).
- 📏 The free play of the pedal has increased (more than 140–150 mm from the floor to the actuation point).
On Almera G15 with a manual transmission it most often fails clutch cable - it stretches or frays. Less commonly, the problem lies in the hydraulic drive (on models with hydraulics) or wear on the release bearing. Before making adjustments, make sure that the malfunction is not related to brake fluid leakage (for hydraulic systems) or deformation of the release fork.
⚠️ Attention: If you hear a grinding or crunching sound when you press the pedal, this is a sign of wear. release bearing. Adjustment will not help here; the part needs to be replaced. Operating the machine in this condition is dangerous: the bearing may jam, which will lead to the destruction of the basket.
- The pedal has become too soft
- There was a burning smell
- Difficulty changing gears
- The car jerks when starting
- Another option
Tools and preparation for adjustment
To adjust the clutch to Nissan Almera G15 no specialized tools needed. A standard set is enough:
- 🔧 Set of open-end wrenches (10, 12 and 14 mm).
- 📏 Ruler or caliper for measuring pedal travel.
- 🔦 Flashlight - engine compartment lighting leaves much to be desired.
- 🧴 WD-40 or similar lubricant for cleaning threaded connections.
- 🧤 Gloves - the work ahead is dirty.
Before starting work, complete the following steps:
Place the car on a level surface and secure it with the handbrake|Disconnect the negative terminal of the battery (optional, for safety)|Clean any dirt from where the cable is attached to the clutch fork|Check the brake fluid level (for hydraulic systems)|Prepare a rag to wipe parts-->
On Almera G15 Access to the clutch mechanism is from above, through the engine compartment. Remove the air filter (unscrew the 4 housing mounting bolts) - this will provide access to the cable and fork. If the adjustment is being made for the first time, take a photo of the original position of the nuts on the cable - this will help put everything back in case of an error.
On models with air conditioning, access to the clutch cable may be difficult due to the pipes. In this case, you will have to temporarily loosen the compressor (without disconnecting the lines!) and move it to the side.
Clutch cable adjustment: step-by-step instructions
On Nissan Almera G15 with a mechanical clutch drive, adjustment is carried out by changing the length of the cable. The procedure takes 15–20 minutes and consists of the following steps:
- Pedal free play measurement. Normal value for Almera G15 —
135–145 mmfrom the floor until resistance begins. If the stroke is less than 120 mm or more than 160 mm, adjustment is required. - Loosening the locknut. It is located at the end of the cable, the clutch fork. Use two wrenches: with one to fix the adjusting nut, with the other to loosen the lock nut.
- Tension adjustment. Turn the adjusting nut clockwise reduces free play of the pedal (the cable is tensioned), counterclockwise - increases.
- Check. After adjustment, press the pedal 3-5 times and measure the stroke again. He should be back in range
135–145 mm.
A common mistake is to overtighten the cable. This leads to incomplete disengagement of the clutch (“drives”), which is why the gears are engaged with a crunch. If after adjustment the pedal becomes too tight, loosen the cable by 1-2 turns of the nut.
| Parameter | Norm for Almera G15 | Consequences of deviation |
|---|---|---|
| Free pedal travel | 135–145 mm |
Less - the clutch “drives”; more - slip |
| Release fork stroke | 25–30 mm |
Increase - release bearing wear |
| Pedal force | 50–70 N (moderate) |
Too tight - wear on the cable; soft - fluid leakage (for hydraulics) |
⚠️ Attention: After adjusting the cable, be sure to check the clutch operation while driving. Accelerate to 40-50 km/h in 3rd gear and press the gas hard. If the engine speed increases, but the car does not accelerate, the clutch slips. If a jerk is felt, the cable will be tightened.
Adjusting the hydraulic clutch (for modifications with GP)
To pieces Nissan Almera G15 (mainly on export versions) a hydraulic clutch drive was installed. Here the adjustment comes down to bleeding the system and checking the stroke of the rod master cylinder. Algorithm of actions:
- Check the fluid level in the reservoir (should be between
MINAndMAX). Top up only DOT-4. - Loosen the bleeder fitting working cylinder (located on the gearbox housing).
- Place a transparent hose onto the fitting and lower the other end into a container with liquid.
- Have an assistant press the clutch pedal all the way and hold it. At this moment, tighten the fitting.
- Repeat the procedure until liquid comes out of the hose without air bubbles.
After bleeding, check the stroke of the master cylinder rod. It should be 20–25 mm. If the stroke is less, replacement is required cuff or the cylinder itself. There are no adjusting nuts on hydraulic systems—the free play of the pedal is adjusted automatically.
What should I do if the pedal remains soft after bleeding?
If the pedal "falls" even after bleeding, check:
1. The tightness of the system - are there any leaks on the main or working cylinder.
2. Condition of the cuffs - when worn, fluid seeps past the piston.
3. Fluid level - if it drops without visible leaks, the problem is breather leak (cylinder replacement required).
4. Presence of air in the system - sometimes bubbles get stuck at the top point of the line. In this case, pump the clutch with the engine running (at 1500 rpm).
Checking the adjustment results
Even if the pedal free play is normal, this does not guarantee that the clutch is working properly. Carry out a test drive using the following algorithm:
- Checking the parking brake. Start the engine, engage 1st gear and slowly release the clutch. The engine should stall. If not, the clutch slips.
- Slope test. On an uphill slope (10–15% slope), brake with the handbrake, engage 1st gear and try to move off. If the car does not roll backwards, the adjustment has been made correctly.
- Checking gear shifting. At a speed of 50 km/h, try engaging 5th gear without releasing the gas. If it turns on easily, the free play of the pedal is normal.
If after adjustment there are still jerks or slipping, the problem may lie in:
- 🔧 Wear driven disk (thickness less than 7.5 mm).
- 🛠 Deformations clutch baskets (diaphragm spring blades are uneven).
- 🔩 Lufte release bearing.
Critical wear of the driven disk on the Almera G15 occurs when the thickness of the friction linings is less than 0.3 mm. In this case, adjusting the cable will not help - the clutch kit (disc + basket + bearing) must be replaced.
Common mistakes when adjusting and how to avoid them
Inexperienced car owners often make the same mistakes, which lead to repeated adjustments or breakdowns. Here are the most common:
- 🔄 Pulling the cable. This leads to incomplete release of the clutch and accelerated wear of the release bearing. The symptom is a crunching noise when shifting gears.
- 🔧 Ignoring cable lubrication. Without lubrication, the cable quickly rusts and jams. Apply lithol or graphite lubricant to the guide bushing.
- 🛑 Adjustment by eye. Always use a ruler to measure pedal travel. An error of even 10 mm can lead to slipping.
- 🔥 Bleeding hydraulics without replacing fluid. Old fluid contains moisture, which lowers the boiling point and causes the clutch to fail when heated.
Another typical problem is uneven wear of the basket petals. This happens if the travel of the release fork was not checked during adjustment. Optimal value - 25–30 mm. If the stroke is less, the fork does not fully move the disc away from the flywheel, which leads to slipping.
After any clutch adjustment, be sure to check the operation of the system while driving. Static testing (on site) does not detect slippage under high loads!
When adjustment does not help: signs of wear on parts
If the problem remains after several adjustment attempts, the main clutch elements are most likely worn out. Here are the signs that require replacement:
| Detail | Signs of wear | Service life (thousand km) |
|---|---|---|
| Driven disk | Slipping, vibrations at start, reduction in lining thickness | 80–120 |
| Basket (pressure disc) | Uneven wear on the petals, cracks on the diaphragm spring | 120–150 |
| Release bearing | Grinding or humming noise when pressing the pedal, play | 100–130 |
| Clutch cable | Jamming, broken fibers, rust on tips | 60–80 |
On Almera G15 Replacing the clutch costs 15–25 thousand rubles (depending on the region and service station). However, if you are confident in your abilities, you can save money by purchasing clutch kit (disc + basket + bearing) for 8–12 thousand rubles and installing it yourself. The main thing is to use original spare parts or analogues from trusted brands (Sachs, LUK, Valeo).
⚠️ Attention: When replacing the clutch with Almera G15 be sure to check the condition flywheel. If there are deep grooves or cracks on its surface, the flywheel must be ground or replaced. Ignoring this rule will lead to rapid wear of the new driven disk.
FAQ: answers to frequently asked questions
Is it possible to adjust the clutch on an Almera G15 without a pit or a lift?
Yes, all adjustment elements are accessible from above, through the engine compartment. Simply remove the air filter. However, to check the travel of the release fork, it is more convenient to use an inspection hole.
How often should the clutch be adjusted?
During normal operation, adjustment is required once every 30–50 thousand km. However, if you often drive in traffic or tow a trailer, check the pedals for free play every 10–15 thousand km.
What should I do if, after adjustment, the pedal becomes too tight?
Most likely the cable will be overstretched. Loosen the adjusting nut 1–1.5 turns and re-measure the pedal stroke. Also check if the cable is stuck in the sheath - this requires replacing it.
Is it possible to use a non-original clutch cable?
Yes, but only from trusted manufacturers (Febi, TRW, Blue Print). Cheap analogues often stretch or tear through 10–20 thousand km. Original cable from Nissan (article 30520-BM40A) lasts 2–3 times longer.
Why did the pedal become soft after replacing the clutch?
This is normal for new parts. Via 200–300 km mileage the pedal will “work in” and become tighter. If the softness persists longer, check the tightness of the hydraulic system (for models with GP) or the cable tension.
