Multiquip 0602122272 Oil Pressure Unit

The Multiquip 0602122272 Oil Pressure Unit is a genuine OEM component designed for DCA and MQP series diesel-powered generators, including models DCA125SSIU, DCA125USI3CAN, DCA125USJ, DCA150SSJU3, DCA220SSJ, DCA220SSJU. As an authentic Multiquip OEM part, the part is manufactured to the same specification as the original unit, ensuring accurate pressure sensing and reliable engine protection across the full range of compatible generator models. This part covers an extensive fitment list spanning Super-Silent, Ultra-Silent, and standard DCA diesel generator configurations, making it the correct choice for fleet operators and service technicians working across multiple units.

Key Features

• Genuine OEM Sensing Accuracy — Manufactured to original specification, this oil pressure unit delivers the correct pressure threshold response required to protect diesel generator engines from low-oil damage.
• Direct-Fit Installation — Engineered as an exact replacement for the original unit, the part connects directly to the existing port and wiring without modification to the sender circuit.
• Broad DCA Series Compatibility — Fits a wide range of Multiquip DCA and MQP series generators including DCA25, DCA45, DCA70, DCA85, DCA100, DCA125, DCA150, DCA180, DCA220, DCA250, DCA300, DCA400, DCA800SSK2, MQP56, and MQP240 models.
• Engine Protection You Can Depend On — A correctly functioning oil pressure unit triggers the generator's shutdown or warning system before oil starvation causes internal engine damage — critical on long-run or remote-site applications.
• Fuel and Ignition System Safety — On diesel generator platforms, a failed oil pressure sender can mask a developing lubrication fault; replacing with a genuine OEM unit restores the integrity of the engine monitoring circuit.

The oil pressure unit is a sender or switch that monitors the lubrication pressure inside the engine and communicates that reading to the generator's control panel or shutdown system. When oil pressure drops below a safe operating threshold — whether from low oil level, pump wear, or a developing internal fault — the unit signals an alert or triggers an automatic shutdown to prevent catastrophic engine damage. When this component fails or reads incorrectly, the engine loses its primary line of defense against oil starvation, putting the entire generator at risk of serious mechanical damage during operation.
