Necessary tools and preparation
Before you begin, make sure you have a complete set of tools and lifting equipment. To replace the clutch with Nissan Almera G15 Access to the bottom of the car will be required, so a lift or inspection hole is required.

- 🛠️ Set of keys and sockets (from 8 to 24 mm).
- 🛠️ Torque wrench (for tightening the basket bolts).
- 🛠️ Mandrel for centering the clutch disc.
- 🛠️ Penetrating lubricant WD-40 or equivalent for rusty bolts.
☑️ Preparation for repairs
Step-by-step instructions for dismantling and installation
The replacement process begins with removing the crankcase protection and disconnecting the battery. Next, you need to remove the front wheels and disconnect the drives from the gearbox to free up space for maneuver. Be careful with the axle seals so as not to damage them when removing them.
The next step is to disconnect the hydraulic clutch drive and cable (if the model is equipped with mechanics) from the release fork. After this, the bolts securing the gearbox to the engine are unscrewed. The gearbox is heavy, so it must be carefully lowered, supporting it from below with a jack or dolly.
Features of removing the gearbox on a Nissan Almera G15
When removing the gearbox, note that the mounting bolts are of different lengths. Write down or sketch their location so as not to confuse them during assembly, otherwise you may damage the crankcase.
After dismantling the gearbox, access to the flywheel and clutch basket becomes available. Inspect the flywheel for cracks and deep grooves; if there are any, it will need to be grooved or replaced. Remove the clutch basket by unscrewing the bolts crosswise and replace the release bearing. Install the new disc using a fine alignment mandrel and tighten the basket bolts to the torque specified in the service book.
Critical errors during repairs
Many owners and even inexperienced craftsmen make gross mistakes that negate the entire repair. The most common problem is improper alignment of the clutch disc. If the disc is installed misaligned, the pedal will vibrate and gears will be difficult to shift, which will lead to rapid failure of new parts.
Never skimp on the release bearing by replacing only the disc and basket. If the bearing is worn out, it will begin to make noise and seize, which can lead to the destruction of the input shaft guide bushing. Replacing the entire set at once is a guarantee of long and trouble-free operation of the transmission.
⚠️ Attention: It is strictly forbidden to lubricate the friction lining of the clutch disc with oil or grease. Even microscopic drops of fat will cause the disc to slip and instantly overheat.
Before installing the new release bearing, apply a small amount of high-temperature grease to the input shaft guide bushing, but do not use excess to avoid getting it on the clutch disc.
