Attention! Installation will require new flywheel/drive plate mounting bolts.
Removing
Models with manual transmission
1. Remove the transmission (see Section 7A), then remove the clutch assembly as described in Section 6.
2. Lock the flywheel ring gear with a tool like the one shown (see illustration). Alternatively, bolt a metal strip to the flywheel and crankcase. Align the flywheel and crankshaft with paint or a suitable marker.
3. Turn off bolts of fastening and remove a flywheel. Do not drop it - the component is very heavy.
Models with automatic transmission
4. Remove the transmission as described in Section 7B.
5. Block the drive disk as described in point 2, then loosen its fastening bolts.
6. Unscrew the bolts and remove the mounting plate, centering ring and drive disk from the end of the crankshaft, marking the location of each of the components.
Inspection
7. On manual transmission models, inspect the flywheel for scratches on the clutch disc contact surface. If this area is worn out, the flywheel can be reground, but it is preferable to replace it. Check flywheel teeth for wear and chipping. On models with a conventional flywheel, crown replacement is possible, but this task should be entrusted to a specialist. On heavier flywheels, this replacement is not possible.
8. On models with automatic transmission, carefully inspect the drive disc and teeth of its crown for damage and signs of wear.
9. If there is any doubt about the condition of the flywheel/drive plate, consult your Opel dealer.
Installation
Models with manual transmission
10. Clean the contact surfaces of the flywheel and crankshaft and remove all traces of blocking compound from the threads of the holes in the crankshaft.
11. Establish a flywheel and insert new bolts of fastening. If the old component is being installed, align the marks made before removal.
12. Block the flywheel and tighten the bolts of its fastening with the required tightening torque (see specs), then tighten the bolts to the desired angle (see specs), using the socket and extension rod, and finally to the desired angle (see specs). It is recommended to use an angle gauge for this to ensure accuracy (see illustrations). If a template is not available, apply white paint to the bolt head and flywheel alignment marks - these will then help ensure that the bolt is turned to the desired angle.
13. Install the clutch as described in Section 6, then remove the locking tool and install the transmission (see Section 7A).
Models with automatic transmission
14. Clean the contact surfaces of the drive plate and crankshaft and remove all traces of blocking compound from the threads of the holes in the crankshaft.
15. Place the drive disc in working position with the centering ring and mounting plate, then screw in the new mounting bolts.
16. Tighten the fastening bolts with the tightening torque specified in the Specifications and tighten them to the required angles (see point 12), then remove the locking tool and install the transmission as described in Section 7B.
