LM600-60 – Textron Aviation OEM Spacer
Available now on the Airparts.aero Marketplace.
Overview
The Lord LM600-60 is a genuine OEM, precision-machined spacer, an integral and flight-critical component of the engine mount assemblies on specific Textron Aviation turboprop aircraft. Manufactured by Parker LORD, this spacer is designed to be used in conjunction with Lord sandwich-style vibration isolators (such as the LM600-9). Its sole, critical function is to establish the precise distance between the elastomeric mounts, applying a specific, engineered amount of pre-compression to the rubber. This pre-compression is essential for "tuning" the engine mount assembly to the correct stiffness and damping characteristics required for effective vibration isolation.
Key Features
- Precision-Machined Length: The length of the spacer is machined to an extremely tight tolerance. This precise dimension is the most critical feature, as it dictates the amount of preload on the elastomeric mounts, directly affecting the performance of the entire vibration isolation system.
- High-Strength Material: Fabricated from a high-strength metal alloy (typically steel or aluminum, depending on the specific application) capable of withstanding the high clamping forces of the mounting bolts and resisting compression or deformation over time.
- Engineered for System Performance: Acts as a key component in the "tuned" spring-mass-damper system of the engine installation. The correct spacer ensures the mount assembly has the intended spring rate to isolate the engine's unique vibrational frequencies.
- Corrosion-Resistant Finish: Treated with a durable, corrosion-resistant plating or finish to protect the component from the harsh operating environment of the engine compartment.
- Genuine OEM Component: As a genuine Lord component specified by Textron Aviation, it guarantees the exact dimensions and material properties required to make the engine mount system perform as designed by the original engineers.

Aircraft Compatibility
The Lord LM600-60 is a specific component designed for the engine mounting hardware stacks on certain high-performance Textron Aviation turboprops. It is essential to consult the aircraft's Illustrated Parts Catalog (IPC) to verify the correct part number and quantity required for your specific aircraft serial number.
- Primary Aircraft Models:
- Cessna 208 Caravan, 208A, 208B Grand Caravan
- Cessna 425 Corsair / Conquest I
Applications
The LM600-60 is a flight-critical component with a singular, vital application:
- Engine Mount Assembly: Used as part of the complete engine mount hardware stack. It is installed between two sandwich mounts on a single mounting bolt, ensuring the correct spacing and performance of the assembly.
- Mandatory Replacement Item: Must be inspected for corrosion, damage, or deformation during engine mount replacement and must be reinstalled correctly to ensure system integrity. It is often replaced as part of a complete engine mount hardware kit.
Why Choose LM600-60?
The performance of a sophisticated vibration isolation system depends on every component working in harmony. The LM600-60 spacer is arguably as critical as the elastomeric mount itself, as an incorrect spacer length would result in an improperly tuned system, leading to excessive vibration, noise, and potential long-term fatigue damage to the airframe and engine components. Using a genuine Lord LM600-60 is the only way to guarantee the dimensional accuracy required for the engine mount system to function as certified. There is no substitute for this precision-engineered component.

The Lord LM600-60 spacer is the key to achieving the correct "pre-compression" of the elastomeric sandwich mounts it is paired with. An elastomeric mount's stiffness (spring rate) is not linear; it changes based on how much it is compressed. The aircraft's engineers perform a complex vibrational analysis to determine the ideal spring rate needed to isolate the specific frequencies produced by the PT6A engine at various power settings. They then translate that required spring rate into a specific amount of pre-compression, which is physically set by the precisely manufactured length of the LM600-60 spacer. Using this specific spacer is therefore fundamental to ensuring the entire multi-million dollar engine and airframe system is protected from damaging harmonic resonance.
Note: Engine mount hardware is flight-critical. 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 of all components in the hardware stack and adhere to all specified torque values.
