OEM Engine Timing Chain Guide Tensioner 11317533462 For BMW E90 E92 E60 E61 E82 E88 E70

11317533462 Engine Timing Guide  For BMW E90 E92 E60 E61 E82 E88 E70 Timing System

1. Function & Purpose

• Core Functions:

  • Guides the timing chain to ensure stable operation and prevent skipping or detachment.

  • Reduces friction between the chain and engine components, minimizing noise and wear.

  • Works with the tensioner to maintain optimal chain tension.

• Critical Importance:

  • A worn or broken guide can cause timing misalignment, leading to severe engine damage (e.g., bent valves).

2.Compatible BMW Models

4.Quality Assurance:

• Manufactured to BMW OEM specifications

• Rigorous quality control testing

• Exact fitment guaranteed for specified applications

• Meets or exceeds original equipment performance standards

5.Applications:

• • Essential component of BMW's timing chain system

  • Works in conjunction with timing chain tensioners and sprockets

  • Critical for maintaining proper valve timing synchronization

  • Helps prevent catastrophic engine timing failure

6. Common Failures & Symptoms

• Typical Issues:

  • Cracking/breakage (plastic degradation) → Timing chain rattling ("ticking" noise).

  • Excessive wear causing chain jump → Fault codes (e.g., P0016 timing correlation).

• High-Risk Scenarios:

  • Mileage exceeding 100,000 km or lack of timing kit maintenance.

7. Maintenance Recommendations

• • Replace as a full timing set (chain + guides + tensioner every 80,000–120,000 km or if noise occurs).

  • Inspect during major engine work (e.g., valve cover replacement).

8. Installation Notes

• Requires specialty tools (e.g., timing pins) for camshaft/crankshaft alignment.

• Clear fault codes and perform idle test post-installation.

• This timing guide is commonly used in BMWs with N-series engines (e.g., N52, N54, N55).

• Verify exact fitment using your VIN (RealOEM or BMW dealership recommended).

• May also fit some B58 (modular engine) applications—check revisions.
