Product Description
Product Overview
Mercedes Benz Engine Timing Gear 2700506100 serves as the central drive component in Mercedes timing systems, precisely transmitting crankshaft power to the camshaft for optimal engine synchronization and performance.
Core Functions & Applications
Primary Functions
- Ensures perfect synchronization between valve timing and piston movement
- Maintains optimal air-fuel ratio and combustion efficiency
- Coordinates with fuel injection and ignition timing systems
Critical Applications
- Mandatory replacement during engine overhaul procedures
- Required when timing chain elongation exceeds 3%
- Essential repair component for P0016/P0017 fault codes
Technical Features & Advantages
| Feature | Technical Advantage |
|---|---|
| Dual-phase alloy steel | Tough core (impact-resistant) + 60HRC surface hardness (300% wear resistance increase) |
| Asymmetric tooth profile | 7dB noise reduction vs conventional gears |
| Laser-etched timing marks | 90% improvement in installation error prevention |
| Nano-composite coating | 0.08 friction coefficient (40% lower than standard gears) |
| Hollow lightweight design | 18% reduced rotational inertia for better engine response |
Working Principle
Power Transmission Path
Crankshaft gear → Timing chain → This gear → Camshaft → Valve train
Synchronization Precision
- ≤0.5° crankshaft angle deviation (equivalent to <0.1mm gear backlash)
- Dynamic compensation: Hydraulic tensioner maintains constant chain tension
Vehicle Compatibility
| Engine Code | Compatible Models | Model Years | Special Notes |
|---|---|---|---|
| M274 DE20 LA | C300(W205)/GLC260(X253) | 2014-2018 | Must upgrade guide rails simultaneously |
| M276 DE35 | E400(W212)/ML350(W166) | 2010-2017 | Not for AMG-tuned versions |
| OM642 DE30 LA | GL350(CDI)/S350D(W222) | 2011-2019 | Requires sulfur-resistant grease |
Installation Precautions
Critical Steps
- Position Locking:
- Use MB SST 000-589-00-30-00 to secure crankshaft at TDC
- Camshaft alignment holes must match perfectly (<0.2mm tolerance)
- Torque Procedure:
Stage 1: Pre-tighten 50Nm → Stage 2: Final 80Nm → Stage 3: Additional 90° rotation
Prohibited Actions
- Never use impact wrenches (causes micro-deformation)
- Stretch bolts are single-use only (MB mandatory standard)
Common Issues & Solutions
| Symptom | Root Cause | Solution |
|---|---|---|
| Cold start "clicking" | PVD coating wear | Replace full timing set (chain+tensioner) |
| P0017 fault code | Gear keyway misalignment | Inspect crankshaft woodruff key |
| Abnormal oil consumption | Sealing surface deformation | Check cylinder head flatness (<0.05mm) |
| High-RPM power loss | Heat treatment defects | Verify part authenticity (counterfeit risk) |
