3. Product Overview

The BMW Engine Timing Guide Rail (timing chain guide) is a critical component of the engine timing system, responsible for securing and guiding the timing chain to ensure precise synchronization between valves and pistons. Part No. 11317504475 is designed for multiple BMW turbocharged and naturally aspirated engines, serving as a direct OEM replacement to address common issues like chain noise or misalignment.

4. Key Features

• Reinforced Material: Glass-fiber-reinforced nylon, resistant to high temps (-40°C to 150°C) and oil degradation.

• Noise Reduction: Smoothed surface minimizes chain friction noise.

• Lightweight Design: Lighter than metal guides, reducing engine load.

• Integrated Structure: Some models include pre-installed grooves for easier assembly.

5. Our Factory Advantages

• Rigorous QC: Each batch undergoes ISO 9001 certification, 100% pressure and dimensional testing.
• OEM Standards: Uses BMW-grade injection molds with ±0.05mm tolerance control.
• Ample Stock: 1000+ units in stock, supports fast shipping (dispatched within 48 hours).
• Warranty: 12-month warranty with technical support for installation queries.
• Cost-Effective: Priced 30%-50% lower than dealerships, without compromising quality.

6. Precautions

⚠ Installation Tips:

• Inspect the timing chain and tensioner for wear; recommend replacing them as a set.

• Always use specialized tools to calibrate timing to prevent engine damage.

⚠ Usage Warnings:

• Do not force installation without confirming engine compatibility.

• If the engine stalled due to timing failure, check for bent valves before replacing the guide.

⚠ Maintenance Notes:

• Monitor oil levels regularly—low oil pressure accelerates guide wear.
• Immediate inspection required if abnormal noises (e.g., metallic rattling) occur.
