Mercedes Benz GLK Engine Car Timing Chain Kit Set 0009932076 2710300963 2710500116 2710500911

1.Overview

    This kit is a 10-piece timing chain set specifically designed for Mercedes-Benz M271 engines, covering essential components for timing system replacement. It fits select 1.8L and 2.0L inline-4 engines (e.g., C-Class, E-Class, GLK models). The timing chain synchronizes the crankshaft and camshaft, ensuring precise valve timing, which is critical for engine performance and longevity.

2. Selection Guide

Note: Confirm compatibility via VIN or OEM part numbers (e.g., A2710502202).

3.Kit Contents 

• Timing Chain – The primary chain that replaces the worn original part.

• Guide Rails / Tensioner Rails – Plastic or metal rails designed to reduce chain friction and noise.

• Tensioner – Automatic or manual adjuster to maintain proper chain tension.

• Sprockets – Gears that drive the chain (may include crankshaft or camshaft sprockets).

• Bolts / Washers – Matching fasteners (some kits may include these).

4. Key Features

• Precision Fit: CNC-machined components ensure exact alignment with M271 engine specs.

• Noise Reduction: Optimized guide rail design reduces chain slap and vibration.

• Corrosion Protection: Chains coated with anti-rust treatment (e.g., zinc or DLC).

• Wear Resistance: Sprockets use case-hardened teeth for extended life.

• OE+ Upgrades: Improved tensioner design over OEM to prevent premature failure.

5. Manufacturing Process

• Chain Production:

  • Material: High-grade alloy steel (DIN 1.6587).

  • Process: Pre-stretched via roller burnishing to reduce elongation.

  • QC: 100% magnetic particle inspection for cracks.

• Guides/Rails:

  • Injection Molding: Glass-fiber-reinforced polyamide (PA6-GF30) for heat resistance.

  • Testing: Simulated 500-hour wear cycles under load.

• Tensioners:

  • Hydraulic: CNC-machined body with precision piston and spring.

  • Leak Test: 100% pressure-checked for seal integrity.

6. Recommended Concurrent Replacements

• Balance Shaft Chain Kit (M271 common failure point).

• Water Pump (prevent coolant leaks during service).

• Camshaft Adjuster Solenoids (if showing wear codes).

7. Installation Notes

• Critical: Align cam/crank marks using MB Star Diagnostic Tool (avoid ±2° deviation).

• Torque Specs: Tensioner bolts (20 Nm + 90° turn), sprocket bolts (50 Nm).

• Break-In: Run engine at 2,000 RPM for 10 minutes to seat tensioner.
