Removal
1. Remove the transmission (see above in Sections Removal and installation of a petrol engine and manual transmission, Removal and installation of gasoline engine and automatic transmission or Removal and installation of diesel engine and gearbox of this Chapter).
2. On manual transmission models, remove the clutch assembly (see Chapter Clutch).
3. Mark the position of the flywheel/drive plate in relation to the crankshaft journal. Note the asymmetrical arrangement of the mounting bolts to eliminate any ambiguity when installing the flywheel/drive plate.
4. To prevent the crankshaft from turning, screw a long bolt into one of the transmission mounting holes on the engine; place a screwdriver against the bolt and wedge the tip of the screwdriver into the teeth of the flywheel/drive disk ring gear (alternatively, you can use a piece of metal rod, bent accordingly).
5. Remove the mounting bolts and remove the flywheel/drive plate assembly from the crankshaft.
Examination
1. Assess the degree of wear of the flywheel/drive disk assembly toothed ring, make sure there are no chipped teeth. The assembly design allows for the replacement of a defective toothed ring individually, however, it would be wiser to entrust this work to auto service specialists: before installation, the ring must be heated to a very specific temperature, accidental excess of which may lead to a violation of the hardening of the teeth.
2. Carefully inspect the assembly for signs of deformation and thread-like cracks around the bolt holes or radiating from the center. If such defects are found, the flywheel/drive disk must be replaced.
3. Assess the degree of roughness of the working surface mating with the clutch disc. If necessary, the flywheel can be machined, although replacement is always preferable.
Installation
1. Wipe the mating surfaces of the flywheel/drive plate and crankshaft journal. Position the assembly on the shaft in accordance with the fit marks made during disassembly.

2. Lightly lubricate the threads of the mounting bolts with locking compound, then screw in the bolts and tighten them in a diagonal order to the required torque.
3. Reinstall the transmission (see sections Removal and installation of a petrol engine and manual transmission, Removal and installation of gasoline engine and automatic transmission or Removal and installation of diesel engine and gearbox of this Chapter).
