The Multiquip 1157291720 is a genuine OEM Screw Lever Adjust Gov DCA-45USJ 4JG1 designed for the DCA-45USJ ultra-silent diesel generator. As a direct OEM replacement sourced through Multiquip's authorized parts network, this component meets the original design specification for the 4JG1 engine governor linkage assembly. Correct fitment is confirmed for DCA-45USJ units, making it a straightforward service part for technicians maintaining this generator series. DHS Equipment supplies this part as a stocked OEM item to support fast, accurate repairs.
Key Features
- OEM Governor Linkage Specification — Manufactured to the original design tolerance for the 4JG1 engine's governor linkage, ensuring the adjustment screw engages the lever arm with the correct thread form and travel range.
- Direct Installation into Existing Assembly — Threads directly into the governor lever assembly on the 4JG1 engine with no re-drilling or modification to the mounting hardware.
- Confirmed Fitment for DCA-45USJ — Engineered specifically for the DCA-45USJ ultra-silent generator platform; use the model code to verify before ordering.
- Precise Governor Control — A correctly adjusted governor screw keeps engine speed stable under load changes; a worn or damaged screw causes erratic RPM and unstable AC output frequency.
- Genuine Multiquip OEM Part — Sourced directly from Multiquip's authorized supply chain under part number 1157291720, ensuring the component matches the original production specification.
The governor adjustment screw works as part of the mechanical governor linkage on the 4JG1 diesel engine, controlling the position of the fuel rack in response to engine load. By setting the correct lever position, it allows the governor to maintain a steady engine speed, which is critical for stable voltage and frequency output from the generator. When this screw becomes stripped, corroded, or misadjusted beyond its serviceable range, the engine loses the ability to regulate speed accurately, resulting in frequency drift and potential damage to connected equipment.
