2760503600 Mercedes-Benz OEM Engine Timing Gear M276 Engine Timing System Parts

1. Product Attribute Table

2. Vehicle Compatibility Table (车辆兼容表)

Applicable Models (M276 Engine Series):

Exclusions:

• Not compatible with M276 turbocharged variants (e.g., M276 DEHLA in E400/S450).

• Incompatible with M278 (V8) or M274 (4-cylinder) engines.

Important:

• Always verify compatibility using the VIN or Mercedes-Benz EPC (Electronic Parts Catalog).

2. Product Function & Purpose

Core Functions:

• Controls the synchronized movement of engine valves and pistons, ensuring precise alignment between intake/exhaust cycles and crankshaft rotation.

• Features high-precision tooth profile design to minimize transmission errors, enhancing engine efficiency and stability.

Material & Manufacturing:

• Genuine OEM parts typically use high-strength alloy steel or sintered metal, heat-treated for improved wear resistance.

• Gear surface may include anti-corrosion coatings or specialized textures to reduce noise.

3. Product Features

OEM Quality Assurance:

• Strictly calibrated to Mercedes-Benz engine ECU specifications, preventing fault codes or performance loss due to dimensional variances.

Durability:

• Designed lifespan typically exceeds 150,000 km (actual performance depends on maintenance conditions).

Recommended Ancillary Components:

• Replacement advised for timing chains, tensioners, and guides simultaneously to avoid uneven wear with new components.

4. Common Installation Issues

Installation Requirements:

• Requires specialized tools (e.g., camshaft locking pins) for timing alignment. Incorrect calibration may cause severe engine damage.

• Torque specifications must strictly follow service manual standards (e.g., M276 timing gear bolts are often single-use and require replacement with new bolts tightened to angular torque).

Failure Symptoms:

• Worn gears may cause timing misalignment, leading to:

  • Hard starting

  • Rough idle

  • Power loss

  • Illuminated check engine light (e.g., code P0016).
