Lemförder 38090 01 - Engine Mounting

Lemförder 38090 01 Engine Mounting

The Lemförder 38090 01 Engine Mounting is a precision‑engineered component designed to secure the engine within the chassis of selected BMW models. It provides a robust, vibration‑damping interface that protects both the engine and the vehicle’s drivetrain from excessive shock and wear.

Key Functional Characteristics

• High‑strength construction: Made from a hardened alloy that resists fatigue and corrosion, ensuring long‑term reliability.
• Hydraulic damping: Integrated fluid chambers absorb engine movement, reducing noise and vibration transmitted to the cabin.
• Exact fitment: Engine‑specific geometry matches the mounting points on the BMW chassis, guaranteeing a secure attachment without modification.
• Easy installation: Designed for quick removal and replacement, with clear alignment features that simplify the process for technicians.
• Weight‑saving design: Lightweight yet strong, contributing to overall vehicle efficiency.

Compatibility Overview

The mounting is engineered for the following BMW platforms:

• BMW X3 (F25) – 2010‑2017 models, including the X3 SAV variant.
• BMW X4 (F26) – 2014‑2018 models, covering both standard and xDrive variants.
• Engine types: 2.0 L 4‑cylinder, B47D20A and N47D20C engines.

Because the mounting interfaces directly with the engine block and chassis, it is essential to verify that the vehicle’s model year and engine code match those specified above before installation.

Installation Procedure

1. Preparation: Disconnect the battery, remove any protective covers, and secure the vehicle on a flat surface.
2. Engine removal: Detach the engine from its current mounting using the appropriate tools, ensuring all bolts and fasteners are removed.
3. Mounting placement: Align the Lemförder 38090 01 with the engine block, matching the mounting holes precisely.
4. Bolt tightening: Install the supplied fasteners in a cross‑pattern sequence, following the manufacturer’s torque specifications to avoid over‑ or under‑tightening.
5. Fluid check: Verify that the hydraulic damping fluid is at the correct level and free of contaminants.
6. Final inspection: Re‑attach any removed components, reconnect the battery, and perform a test drive to confirm smooth operation.

Performance Benefits

• Reduced vibration: The hydraulic damping system significantly lowers engine‑induced vibrations, enhancing passenger comfort.
• Improved durability: By limiting engine movement, the mounting protects critical drivetrain components from premature wear.
• Noise reduction: The design attenuates engine noise, contributing to a quieter cabin environment.
• Consistent alignment: Maintains optimal engine positioning, which is vital for accurate sensor readings and efficient power delivery.

Maintenance Tips

• Inspect the mounting for signs of wear or damage during routine service intervals.
• Check hydraulic fluid levels annually and replace if necessary to preserve damping performance.
• Avoid over‑tightening fasteners during reassembly; use a calibrated torque wrench.
• Keep the mounting area clean to prevent debris from interfering with bolt seating.
