Design Philosophy and Engineering Excellence

The Lesjöfors 8137243 Bonnet embodies the company’s commitment to precision engineering. Each unit undergoes rigorous testing, including:

1. Static Load Testing: Verifies that the spring can sustain maximum cargo weight without deformation.
2. Dynamic Cycling: Simulates thousands of opening and closing cycles to ensure longevity.
3. Temperature Extremes: Assesses performance from -40°C to +80°C, guaranteeing reliability in both cold and hot environments.

Installation Guide for the Hyundai ix20

Installing the Lesjöfors 8137243 Bonnet is a straightforward process that can be completed with basic hand tools. Follow these steps for optimal results:

1. Remove the Existing Damper: Detach the old gas spring by loosening the mounting bolts and carefully lowering the hatch.
2. Align the New Bonnet: Position the 8137243 bonnet so that its mounting flange sits flush against the rear frame.
3. Secure with Bolts: Tighten the mounting bolts to the manufacturer’s specified torque (typically 20 Nm). Use a calibrated torque wrench for precision.
4. Test the Operation: Open and close the hatch multiple times to ensure smooth movement and proper load distribution.
5. Final Inspection: Check for any play or misalignment. Adjust if necessary before final tightening.

Maintenance Tips for Longevity

• Regular Inspection: Check for signs of wear, corrosion, or oil leakage every 12 months.
• Lubrication: Apply a light coat of high‑temperature grease to the pivot points every 6 months.
• Cleaning: Wipe the bonnet with a dry microfiber cloth to remove dust and debris that could impede movement.
• Replacement Interval: While the bonnet is designed for long life, recommend replacement after 10 years or 200,000 km if any performance issues arise.
