Installation Overview

The Sachs 1874 048 000 set is engineered for straightforward integration into existing flywheel assemblies. Follow these steps to ensure optimal performance:

1. Preparation: Clean the flywheel surface and remove any old fasteners or debris.
2. Positioning: Align each screw with its corresponding hole, ensuring that the threads match the flywheel’s mating surfaces.
3. Tightening Sequence: Use a calibrated torque wrench to tighten screws in a star pattern. Apply torque gradually up to the specified limit of 350 Nm.
4. Locking: Install the provided torque‑locking washers on each screw head to prevent loosening during operation.
5. Final Check: Verify that all screws are evenly tightened and that there is no visible play or misalignment.

Maintenance Tips

• Inspect the screw set annually for signs of wear, corrosion, or loosening.
• Reapply a light coat of anti‑seize lubricant to threads before reassembly if necessary.
