Installation Guide

1. Preparation: Clean the exhaust surface and clamp area with a solvent to remove oil, grease, or rust. Ensure the mounting flange is free of debris.
2. Positioning: Place the BOSAL clamp over the exhaust component (catalytic converter or muffler) so that the inner face aligns flush with the flange.
3. Tightening: Use a torque wrench to tighten the clamp to the manufacturer’s specified torque value (typically between 20–30 Nm). This ensures consistent clamping force without over‑tightening.
4. Verification: Inspect the clamp for uniform pressure distribution and confirm that no gaps exist. Recheck torque after a short driving period to account for thermal expansion.

Maintenance Tips

• Inspect clamps periodically for signs of corrosion or wear, especially in high‑humidity environments.
• Avoid using excessive force when tightening; rely on calibrated torque tools.
• If a clamp shows visible damage, replace it immediately to prevent exhaust leaks and potential engine performance issues.
