The Woodward 8923-2031 is a specific part number that identifies a KIT – LECM, HARDWARE, SMALL MTG, VIBRATION ISOLATION. This is not an electronic control module itself, but rather a mounting kit designed to help install and protect a Large Engine Control Module (LECM), specifically smaller LECM units.
WOODWARD 8923-2031: LECM Small Mounting & Vibration Isolation Kit
The Woodward 8923-2031 is a specialized hardware kit manufactured by Woodward. Its primary function is to provide the necessary mounting hardware and vibration isolation for smaller Woodward Large Engine Control Modules (LECMs).
Product Overview
- Product Type: Mounting and Vibration Isolation Kit
- Manufacturer: Woodward
- Part Number: 8923-2031
- Function: This kit is designed to physically secure a compact LECM unit in its operating environment while minimizing the impact of engine vibrations. Vibration isolation is crucial for protecting sensitive electronic components within the control module, extending its lifespan, and ensuring stable operation.
- Contents: While the exact contents aren’t detailed in public summaries, a typical kit of this nature would include:
- Mounting brackets
- Vibration isolators (e.g., rubber bushings or specialized mounts)
- Fasteners (screws, bolts, washers, nuts) appropriate for the mounting application.
Detailed Description
The longevity and reliability of industrial electronic controls like LECMs are significantly impacted by environmental factors, particularly vibration. Engines, especially large industrial ones, produce considerable vibration that can stress circuit boards, connections, and internal components over time, leading to premature failure.
The 8923-2031 kit addresses this by providing a dedicated solution for isolating the LECM from these harmful vibrations. The “small mounting” designation suggests it’s tailored for LECM models that have a more compact form factor, requiring specific mounting points or smaller footprint solutions.
Key aspects of such a kit:
- Vibration Absorption: The isolators in the kit are designed to absorb and dampen vibrations transmitted from the engine block or mounting frame, preventing them from reaching the sensitive electronics of the LECM.
- Secure Mounting: The hardware ensures the LECM is securely fastened, preventing movement or detachment during operation, even in high-vibration environments.
- Enhanced Reliability: By mitigating vibration stress, the kit contributes directly to the overall reliability and operational lifespan of the LECM.
- Simplified Installation: Kits like this simplify the installation process by providing all necessary, purpose-designed hardware, ensuring proper mounting and isolation without custom fabrication.
Applications
The Woodward 8923-2031 mounting kit would be used wherever a smaller Woodward LECM (Large Engine Control Module) is installed on or near a large industrial internal combustion engine. This includes:
- Power Generation: For engine-driven generator sets (gensets).
- Oil & Gas: For engines driving compressors or pumps in pipeline, drilling, or production facilities.
- Industrial Prime Movers: Any industrial application where large engines serve as prime movers for machinery.
- Marine Applications: In marine propulsion or auxiliary power systems where engines operate in demanding conditions.
Compatibility and Replacement Notes
It’s important to note the current status of the 8923-2031:
- Obsolescence: The 8923-2031 is listed as part of the 723, 723+, and 828 product line (or associated accessories for these lines), which Woodward has officially inactivated (End-of-Life). This decision was primarily due to component obsolescence. This means direct sales and new production of the 8923-2031 are discontinued. 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 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.
