The Multiquip M1924200104 is a genuine OEM BU-4JJ1T Isuzu Motor designed for DCA45USI4CAN ultra-silent diesel-powered generators. As a direct Multiquip OEM component, this motor is sourced to the original build specification for the DCA45USI4CAN series, including the FR variant, ensuring correct mechanical and electrical compatibility straight out of the box. If you are rebuilding, repairing, or restoring a DCA45USI4CAN unit, part number M1924200104 is the correct factory replacement to specify.

Key Features

• Genuine OEM Build Integrity — Sourced directly from Multiquip to match the original Isuzu BU-4JJ1T motor specification, ensuring correct output characteristics and mechanical tolerancing for generator applications.
• Direct-Mount Compatibility — Engineered to install into the DCA45USI4CAN generator platform without adaptation, aligning with the existing mounting points and drive interface of the host unit.
• Confirmed Fitment — Verified for DCA45USI4CAN and DCA45USI4CAN (FR) ultra-silent diesel generator models; always cross-reference your unit's model code before ordering.
• Sustained Generator Output — A correctly functioning motor keeps the generator delivering consistent power output; a worn or failed motor unit results in reduced performance, unstable load handling, or complete loss of generation capability.
• Authorized OEM Supply — Sold by DHS Equipment as a genuine Multiquip OEM part, backed by verifiable part number M1924200104 for procurement, service records, and fleet maintenance documentation.

The BU-4JJ1T Isuzu Motor is the core prime mover assembly within the DCA45USI4CAN ultra-silent generator, converting diesel fuel combustion into the rotational energy that drives the alternator to produce electrical power. The condition of this motor directly determines the generator's ability to maintain stable voltage and frequency under load — critical in applications where sensitive equipment or continuous jobsite power is required. When the motor wears, loses compression, or fails, the generator can no longer sustain its rated output, making a like-for-like OEM replacement the most reliable path to restoring full operational capacity.
