J-23502-1 – Lord Engine Mount Kit for Cessna Aircraft
Available now on the Airparts.aero Marketplace.
Overview
The Lord J-23502-1 is a genuine OEM, flight-critical engine mount kit specifically engineered for the Cessna 208 and 208B Caravan series of aircraft. Manufactured by Parker LORD, the global leader in vibration control technology, this kit provides a complete, factory-specified set of four individual J-9613-12 elastomeric mounts. This engineered system is designed to support the full weight and torque of the Pratt & Whitney Canada PT6A turboprop engine while isolating the airframe, avionics, and occupants from its intense, high-frequency vibrations.
Key Features
- Complete, Matched Set: Contains a full ship-set of four (4) individual Lord J-9613-12 mounts. Replacing all mounts simultaneously with a matched set is a critical requirement for ensuring the system performs as designed and that loads are distributed evenly.
- Tuned Vibration Isolation: Each mount is specifically "tuned" with a proprietary elastomer that has the precise spring rate (stiffness) and damping characteristics required to isolate the unique vibrational frequencies of the PT6A engine on the Caravan airframe.
- Dynafocal Design Principle: The mounts are designed to be installed at a specific, focused angle. This dynafocal arrangement ensures that the vibrational forces produced by the engine are directed towards the aircraft's center of gravity, providing maximum isolation and a significantly smoother, quieter cabin environment.
- High-Strength Bonded Construction: Each individual mount features a high-strength chemical bond between the specially formulated elastomer and the corrosion-resistant steel mounting plates. This bond is stronger than the elastomer itself, preventing delamination under the extreme loads of flight.
- Genuine Lord OEM Kit: As the genuine OEM kit specified by Textron Aviation, it guarantees that every component meets the original Type Certificate requirements for performance, safety, and durability.

Applications
The J-23502-1 kit is the flight-critical solution for engine installation and maintenance:
- Engine Installation: The only certified mounting system for installing a PT6A engine onto the Cessna Caravan airframe.
- Scheduled Maintenance: Engine mounts are life-limited components that must be inspected regularly for elastomer degradation (cracking, hardening, fluid contamination) and compression set. This kit is used to replace time-expired or unserviceable mounts.
- Vibration Resolution: The primary solution for resolving issues of increasing airframe vibration and cabin noise, which are often the first indicators of aging engine mounts.
Why Choose J-23502-1?
The engine mounting system is a critical airframe structure. Worn or failed mounts can lead to a severe increase in vibration, which can cause fatigue damage to the airframe, engine plumbing, and avionics, and can be physically fatiguing to the flight crew. Using the genuine Lord J-23502-1 kit is the only way to ensure the vibration isolation system performs as the engineers intended. The matched set of mounts guarantees a balanced installation, restoring the aircraft to its original smooth, quiet flight characteristics and protecting the long-term value and safety of the airframe.

The Lord J-23502-1 kit utilizes the "Dynafocal" engine mounting principle, a significant advancement over older "bed" style mounts. In a Dynafocal system, the mounts are positioned at compound angles so that imaginary lines drawn through the center of each mount's most flexible axis all converge on a single "focal point" located at the aircraft's center of gravity (CG). This geometric arrangement allows the engine/propeller combination to pivot softly around the CG in response to vibrational forces, effectively isolating these forces from the airframe structure itself. The precisely engineered stiffness of the J-9613-12 mounts included in this kit is essential to achieving this tuned dynamic response.
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 current Textron Aviation maintenance manual. Pay close attention to the installation orientation and the specified torque values for all mounting hardware.
