LM600-9 – Textron Aviation Lord Engine Mount
Available now on the Airparts.aero Marketplace.
Overview
The Lord LM600-9 is a genuine OEM "sandwich" type vibration isolator mount, a flight-critical component engineered to secure the engine to the airframe on high-performance Cessna turboprop aircraft. Manufactured by Parker LORD, the global leader in vibration control technology, this mount is designed to support the engine's weight and manage propeller torque while isolating the airframe from the intense vibrations of the turbine engine. The LM600-9 is constructed from high-strength steel plates bonded to a specially formulated neoprene elastomer, ensuring durability, reliability, and a significant reduction in cabin noise and airframe fatigue.
Key Features
- Elastomeric Isolation Technology: Utilizes a specially formulated neoprene elastomer, chemically bonded to steel plates. This design effectively absorbs and dampens the vibrational energy produced by the turbine engine and propeller, preventing it from being transmitted to the airframe.
- Superior Vibration Control: When properly installed as part of a complete set, these mounts provide excellent isolation of engine vibration across a wide range of frequencies, resulting in a smoother, quieter flight and reduced pilot and passenger fatigue.
- High-Strength Bonded Construction: The bond between the elastomer and the steel plates is a critical chemical bond, created under high pressure and heat. This process ensures the bond is stronger than the elastomer itself, preventing delamination and failure under high G-loads and torque.
- Engineered for Turboprops: Specifically designed to handle the unique vibrational signature and high torque output of turboprop engines like the Pratt & Whitney Canada PT6A.
- Genuine OEM Component: As a genuine Lord mount specified by Textron Aviation, it guarantees the correct spring rate, material composition, and performance characteristics required by the aircraft's original Type Certificate.

Applications
The LM600-9 is a flight-critical component with several key roles:
- Engine Mounting & Support: Serves as the primary structural link between the engine and the engine mount frame, supporting the full weight of the powerplant.
- Vibration Isolation: Its primary function is to protect the airframe, instruments, and occupants from the damaging and fatiguing effects of engine vibration.
- Torque Management: Designed to react to and manage the high torque produced by the engine during power changes.
- Scheduled Maintenance Item: These mounts are considered consumable items and must be inspected for wear, compression set, and elastomer degradation at regular intervals and replaced as a complete set when they reach their service limits.
Why Choose LM600-9?
Worn or failed engine mounts can lead to a dramatic increase in cabin noise and vibration, accelerated fatigue cracking in the engine mount and firewall structure, and potential damage to engine accessories and plumbing. Using genuine Lord LM600-9 mounts is the only way to ensure the vibration isolation system performs as designed by the aircraft's engineers. The specific spring rate and damping characteristics of the elastomer are precisely tuned for the engine and airframe combination. For a component this critical to both comfort and structural integrity, there is no substitute for the proven performance and certified quality of a genuine Lord mount.

The Lord LM600-9 sandwich mount is engineered to provide controlled stiffness in multiple axes. It is relatively soft along the axis of vibrational input to provide isolation, while remaining stiff in other directions to properly support the engine's weight and resist torque. A typical installation consists of four or six mounting assemblies, with each assembly often comprising two LM600-9 sandwich mounts and a precisely machined spacer (e.g., LM600-20, LM600-12). The spacer is critical, as it pre-compresses the elastomer to a specific degree, "tuning" the mount to the correct spring rate for the application. This pre-compression is essential for the mount's performance and longevity.
Note: Engine mounts are flight-critical components and should always be replaced as a complete set to ensure uniform performance and prevent uneven loading. Installation must be performed by a certified A&P mechanic in strict accordance with the aircraft's current maintenance manual. Pay close attention to the installation orientation and the specified torque values for all mounting hardware.
