The Multiquip 1824100990 Oil Pressure Unit is a genuine OEM component designed for DCA-series ultra-silent and super-silent diesel generators, including the DCA25USI, DCA25SSIU3, DCA20SPXU2, DCA20SPXU2D, DCA25USI2, DCA25USI4CAN, DCA25, and TLG12SPX. As a direct Multiquip OEM replacement, part 1824100990 is manufactured to the same specification as the original unit installed at the factory, ensuring consistent performance and accurate oil pressure monitoring across all compatible generator models. Sourcing a genuine OEM part means you get the correct sender characteristics — no guesswork on calibration or signal output. DHS Equipment stocks this part to support fast fulfillment for contractors, rental fleets, and service technicians who depend on these generators to stay running.
Key Features
- Calibrated Signal Output — Matched to the OEM gauge and control circuit specifications of DCA-series generators, ensuring accurate oil pressure readings without signal offset or drift.
- Genuine OEM Component — Multiquip 1824100990 is a factory-original part, not a generic substitute, so thread pitch, connector type, and pressure range align exactly with the original installation.
- Broad DCA-Series Fitment — Confirmed for DCA25USI, DCA25SSIU3, DCA20SPXU2, DCA20SPXU2D, DCA25USI2, DCA25USI4CAN, DCA25, and TLG12SPX generator models.
- Protects Engine Longevity — A functioning oil pressure unit gives operators and control systems the data needed to detect low-pressure conditions before engine damage occurs; a failed sender leaves the engine running blind.
- Direct Installation — Designed to thread into the existing port and connect to the OEM wiring harness without modification, simplifying replacement during scheduled service or fault diagnosis.
The oil pressure unit — sometimes called an oil pressure sender or switch — monitors engine oil pressure and transmits a corresponding signal to the generator's gauge or electronic control module. This reading is critical for engine protection: most generator control systems will trigger a shutdown or alarm if oil pressure drops below a safe threshold, and that response depends entirely on the sender delivering an accurate signal. When the oil pressure unit fails, readings may become erratic, stick at a fixed value, or drop to zero, making it impossible to distinguish a genuine low-pressure condition from a faulty sensor — both of which put the engine at risk. Replacing a worn or failed unit with a genuine Multiquip 1824100990 restores accurate monitoring and allows the generator's protection systems to function as designed.
