Fastening procedure highlights

1. Clean and inspect bolt threads and mating surfaces; replace damaged bolts.
2. Use anti-seize only if specified by manufacturer; otherwise install dry or per spec.
3. Tighten bolts in a crisscross/star pattern to distribute load evenly.
4. Torque in multiple increments (e.g., 30%, 60%, 100%) rather than single-pass final torque.
5. For flywheel bolts, follow any required torque-plus-angle sequence from the flywheel or service manual.
