LEMFÖRDER 37747 01 Engine Mounting For Mercedes-Benz B-CLASS SPORTS TOURER

Engine Mounting for Mercedes‑Benz B‑Class Sports Tourer (W246, W242)

The LEMFÖRDER 37747 01 engine mounting is a precision component engineered to provide optimal vibration isolation and structural support for the powertrain of the Mercedes‑Benz B‑Class Sports Tourer. Designed specifically for models produced between 2011 and 2018, this mounting ensures that the engine remains securely positioned while reducing noise, vibration, and harshness (NVH) transmitted to the vehicle cabin.

Key Functional Characteristics

• Vibration Damping: The mounting incorporates a high‑performance elastomeric compound that absorbs engine vibrations. This results in smoother operation and extended component life.
• Load Distribution: Engine forces are evenly spread across the chassis, minimizing stress concentrations on suspension and frame elements.
• Durability: Constructed from corrosion‑resistant steel with a protective coating, the mounting withstands harsh operating environments and prolonged exposure to road salts and moisture.
• Compatibility: Tailored for the right‑hand upper engine position in both W246 (2011‑2018) and W242 (2011‑2018) variants, ensuring seamless integration with existing vehicle architecture.

Material Composition

The mounting is fabricated from a high‑strength alloy steel that offers excellent fatigue resistance. The elastomeric insert is made of a proprietary polyurethane blend engineered for high temperature stability and low compression set, maintaining performance across the full operating temperature range of the B‑Class Sports Tourer.

Installation Overview

Installing the LEMFÖRDER 37747 01 mounting involves the following steps:

1. Preparation: Remove the existing engine mount and clean all contact surfaces to eliminate debris and old gasket material.
2. Alignment: Position the new mounting in alignment with the engine block and chassis brackets, ensuring that all fastener holes match precisely.
3. Securing: Tighten the mounting bolts to the manufacturer’s torque specifications using a calibrated torque wrench. This guarantees uniform clamping force across all attachment points.
4. Verification: Inspect for any play or misalignment, and perform a short test drive to confirm that vibration levels are within acceptable limits.

Performance Benefits

• Reduced NVH: The elastomeric damping layer significantly lowers the transmission of engine vibrations to the cabin, enhancing passenger comfort.
• Extended Component Life: By distributing loads evenly and minimizing peak stresses, the mounting helps prolong the lifespan of both the engine and chassis components.
• Improved Fuel Efficiency: A well‑aligned engine mount reduces parasitic drag caused by vibration-induced misalignments, contributing to marginal gains in fuel economy.

Maintenance Recommendations

Although the mounting is designed for long‑term reliability, periodic inspections are advisable. Check for:

• Visible wear or cracking of the elastomeric insert.
• Loose or corroded fasteners.
• Any signs of oil leakage that could compromise the integrity of the mount.

Replace the mounting if any of these issues are detected to maintain optimal vehicle performance and safety.
