Removal and installation the flywheel/drive disc (Honda Civic 6)

Removal

1. Jack up the vehicle and place it on supports. Remove the gearbox (see Chapter Gearshift box).

2. On models with manual transmission, remove the clutch assembly (see Chapter Clutch and drive shafts). Immediately check the condition of the clutch components and the guide bearing.



3. Remove the flywheel/drive plate mounting bolts from the crankshaft (see accompanying illustration). If the shaft starts to turn while loosening the bolts, remove the starter (see Chapter Engine electrical equipment) and wedge a screwdriver between the teeth of the flywheel ring gear (manual transmission), or insert a long punch into one of the holes of the drive disk, resting it against the protrusion on the block (automatic transmission). 4. Remove the flywheel/drive disk from the crankshaft.

Note: The flywheel/drive plate is a fairly heavy component - it may be wise to have an assistant assist you.

5. Thoroughly wipe the flywheel, completely removing traces of oil and grease. Check the flywheel working surface for cracks, grooves left by the rivet heads of the friction disk, traces of overheating and scoring. Minor defects can be eliminated using fine-grained sandpaper. Check the toothed ring for cracks and chipped teeth. Place the flywheel on a flat surface to assess its flatness (use a flatness meter).



6. Wipe the mating surfaces of the flywheel/drive plate and crankshaft. If there is evidence of oil leakage from the crankshaft rear oil seal, replace it (see Replacing the rear crankshaft oil seal).

Installation

1. Install the flywheel/drive plate onto the crankshaft.

Note. On some engines, a guide pin is provided, or the mounting holes are located asymmetrically, which guarantees an unambiguous fit of the part. Before screwing in the mounting bolts, lubricate the threaded part with a fixing sealant.

2. Block the flywheel/drive disk from turning (see paragraph 3), tighten the mounting bolts to the required torque in a diagonal pattern.

3. Further installation is carried out in the reverse order of dismantling.
