Installation Guidelines

Installing the flywheel with the Sachs 1874000066 set requires careful attention to torque sequencing and alignment. Follow these steps for a reliable installation:

1. Preparation: Clean the flywheel hub and crankshaft threads thoroughly to remove any debris or old threadlocker.
2. Threadlocker Application: Apply a high‑strength threadlocker to each bolt head before insertion.
3. Bolt Insertion: Insert the bolts manually to ensure proper seating, then use a torque wrench for final tightening.
4. Torque Sequence: Tighten the bolts in a star pattern, progressing from 20 Nm to 40 Nm as specified by the manufacturer.
5. Final Check: Verify that all bolts are uniformly tightened and that the flywheel is centered on the crankshaft.

Maintenance Tips

To preserve the integrity of the flywheel and its fasteners, consider the following maintenance practices:

• Inspect bolts for signs of wear or loosening during routine service intervals.
• Avoid over‑torquing, which can strip threads or damage the flywheel hub.
• Use a fresh batch of threadlocker for each installation to maintain consistent performance.
• Store spare bolts in a dry, temperature‑controlled environment to prevent corrosion.
