2. Vehicle Compatibility Table

Note: Always verify fitment using your VIN number before purchase. Some modified or high-performance variants may require additional checks.

3. Product Features

• Material:

  • Housing: High-strength aluminum alloy, lightweight and heat-resistant.

  • Internal Components: Precision steel piston + Teflon sealing ring for reduced friction.

• Design:

  • Hydraulic self-adjusting mechanism for real-time chain slack compensation.

  • Integrated check valve prevents oil pressure loss and tension failure.

• Compatibility: OEM equivalent (Original BMW Part No.: 11311439552).

4. Product Advantages

• Reliability:

  • Solves common timing chain rattle and jumping issues in older N-series engines, reducing risk of valve collision.

  • Durability tested for over 100,000 km (with proper maintenance).

• Performance:

  • Stabilizes timing system, ensuring precise valve timing and optimized engine power output.

• Cost-Effectiveness:

  • 30%-50% more affordable than dealership OEM parts.

5. Manufacturing Process

• Standards: Produced in an ISO 9001-certified factory, compliant with BMW TL/TS specifications.

• Key Processes:

  • CNC precision machining (tolerance ≤0.01mm).

  • 100% hydraulic pressure testing (simulating engine oil pressure conditions).

• Quality Control: 3-stage inspection (dimensions, sealing, dynamic tension testing).

6. Installation Guide (Summary)

Tools Required: Torque wrench, timing tool kit, new gasket.

Steps:

1. Disconnect the battery and remove the engine cover/timing case.

2. Release chain tension, remove the old tensioner (note oil line connections).

3. Clean the mounting surface, apply a thin oil film, and install the new tensioner (torque: 25-30Nm).

4. Verification:

   • Manually rotate the crankshaft twice to check timing marks.

   • Start the engine and listen for abnormal noises; verify oil pressure.

Warning: Non-professionals should seek authorized service to avoid severe engine damage!
