The Woodward 8923-2049 is a specific part number that identifies a mounting kit for a Large Engine Control Module (LECM). Specifically, it’s designed to provide vibration isolation for LECM units in challenging environments, such as marine applications, where robust protection against engine vibrations is crucial.
WOODWARD 8923-2049: LECM Marine Vibration Isolation & Mounting Hardware Kit
The Woodward 8923-2049 is a specialized hardware kit manufactured by Woodward. Its primary function is to physically secure a Woodward Large Engine Control Module (LECM) while specifically minimizing the impact of harsh engine vibrations, especially in marine environments or other applications where high vibration levels are present.
Product Overview
- Product Type: Mounting and Vibration Isolation Kit / Hardware Kit
- Manufacturer: Woodward
- Part Number: 8923-2049
- Function: This kit provides the necessary hardware to mount an LECM and, crucially, incorporates vibration isolation elements. These elements are designed to absorb and dampen vibrations transmitted from the engine or its mounting structure, protecting the sensitive electronic components within the LECM. The “Marine Vibration Isolation” designation highlights its suitability for environments with particularly stringent requirements for shock and vibration dampening.
- Contents: A kit of this nature would typically include:
- Specialized mounting brackets.
- High-performance vibration isolators (e.g., elastomeric mounts, rubber bushings, or spring-based dampers).
- Appropriate fasteners (screws, bolts, washers, nuts) designed for secure and isolated mounting.
- Potentially a backshell for IP69K rating when combined with specific LECM AUX modules, as indicated in some product references.
Detailed Description
The operational integrity and lifespan of sophisticated electronic controls like LECMs are highly susceptible to mechanical stress, with vibration being a primary culprit in industrial and marine settings. Engines, especially large ones, generate significant vibrations that can lead to fatigue, loosening of connections, and eventual failure of electronic components.
The 8923-2049 kit is engineered to counter these forces. Its “Marine Vibration Isolation” aspect suggests that the isolators are designed to meet rigorous standards for shock and vibration dampening, often exceeding those for land-based industrial applications.
Key aspects of such a kit:
- Superior Vibration Absorption: The isolators are specifically chosen or designed to effectively absorb and dissipate a broad range of vibration frequencies and amplitudes, preventing them from reaching the LECM’s internal electronics.
- Robust and Secure Mounting: The hardware ensures the LECM is securely fastened, preventing any unwanted movement or detachment, even under dynamic operating conditions.
- Enhanced Reliability and Longevity: By effectively isolating the LECM from mechanical stress, the kit directly contributes to the control module’s overall reliability, reducing the risk of premature failure and extending its operational life.
- Designed for Harsh Environments: The components of the kit are likely made from materials suitable for marine or other harsh industrial environments, resisting corrosion and degradation over time.
- Integrated Solution: It offers a pre-engineered solution for mounting and isolation, simplifying installation and ensuring that the LECM is protected according to manufacturer specifications.
Applications
The Woodward 8923-2049 mounting kit would be used wherever a Woodward LECM (Large Engine Control Module) is installed in an environment subject to significant vibration, particularly:
- Marine Propulsion and Auxiliary Power: For engines on ships, boats, or offshore platforms where continuous vibration and shock are prevalent.
- Power Generation: For engine-driven generator sets (gensets) in applications with high vibration or strict durability requirements.
- Oil & Gas: For engines driving compressors or pumps in pipeline, drilling, or production facilities where equipment is exposed to harsh conditions.
- Heavy Industrial Prime Movers: Any large industrial application where engines generate substantial vibration and long-term reliability of control electronics is paramount.
Compatibility and Replacement Notes
It’s important to note the current status of the 8923-2049:
- Obsolescence: The 8923-2049, as an accessory for the LECM (which includes models from the 723, 723+, and 828 product line), is likely inactivated (End-of-Life) by Woodward. Woodward has discontinued new production and direct sales of the older LECM product lines and their associated accessories due to component obsolescence. As of July 2025, any limited repair support that might have been available (which was typically until September 2024 for this line’s related products) is now highly restricted or unavailable due to parts availability.
- Replacement: For new installations or replacements where this kit was previously used, you would typically need to consult with Woodward or an authorized distributor. Modern LECM control systems (like newer LECM SA variants or the Flex500 series) would come with their own recommended mounting and vibration isolation solutions, or new, compatible universal mounting hardware may be specified.
