Removal
Remove the starter as indicated in chapter 12. Remove the clutch mechanism (chapter 6) or automatic transmission (chapter 7).
If the transmission is on the engine, remove the clutch release bearing and coupling (chapter 6).
Although the flywheel can only be installed in one position, subsequent assembly can be simplified by making marks between the flywheel and the end of the crankshaft.
Wed the gear teeth with something so that the flywheel does not turn. Access for work is open through the starter opening.
Loosen the bolts and remove the flywheel, being careful (he is heavy).
Inspection
If the teeth on the flywheel ring gear are badly worn or some teeth are missing, it is necessary to remove the ring gear and install a new one.
The old crown can be removed by cutting the gap between the two teeth with a hacksaw. Be careful not to damage the flywheel during this operation and protect your eyes.
The new ring gear must be heated to 180-230°C, and it is better if this work is done in a Vauxhall/Opel workshop. The new ring gear must not be overheated, this will worsen the metal structure.
The crown should be placed on the base by gently tapping with a hammer, and then left to cool gradually - the contraction of the metal during cooling ensures a secure fit.
If the contact surface of the friction lining is scratched, signs of hairline cracks appear (caused by overheating), — you can give the flywheel for surface grinding, provided that the overall thickness of the flywheel will not be significantly reduced. Consult a specialist, and if grinding is not possible, replace the flywheel.
Installation
Place the flywheel on the end of the crankshaft and align the marks made earlier on the flywheel and crankshaft.
Install new flywheel bolts and tighten them to the specified torque in two stages, first locking the flywheel to prevent it from turning.
Where required, install the clutch release bearing and its sleeve (chapter 6).
Install the clutch (chapter 6) or automatic transmission as specified in chapter 7.
Install the starter as shown in chapter 12.
