Multiquip 8973148250 Nozzle Holder Assembly DCA25USI 4LE2

The Multiquip 8973148250 Nozzle Holder Assembly DCA25USI 4LE2 is a genuine OEM component designed for the DCA25USI ultra-silent diesel generator. As a direct Multiquip OEM part, 8973148250 is manufactured to the exact tolerances required by the 4LE2 diesel engine powering the DCA25USI, ensuring the fuel injector nozzle is seated and secured correctly within the cylinder head. Sourced directly through authorized Multiquip supply channels, this assembly delivers the fit and function your generator depends on.

Key Features

• OEM Injector Nozzle Retention — Manufactured to the precise seating geometry of the Isuzu 4LE2 engine, ensuring the fuel injector nozzle is held at the correct depth and angle for proper fuel atomization.
• Direct-Fit Installation — Engineered to drop into the DCA25USI cylinder head without modification, using the same mounting interface as the original assembly.
• Confirmed Fitment for DCA25USI — Verified for use on the Multiquip DCA25USI ultra-silent diesel generator equipped with the 4LE2 engine platform.
• Protects Fuel Injection Efficiency — A correctly installed nozzle holder maintains injection pressure and spray pattern; a worn or damaged holder can cause misfires, rough running, and excessive fuel consumption.
• Genuine Multiquip OEM Part — Supplied as an authentic replacement component, carrying the part number 8973148250 and meeting the original equipment specification for the DCA25USI generator.

The nozzle holder assembly secures the fuel injector nozzle inside the engine's cylinder head, holding it at the precise position needed for accurate fuel delivery into the combustion chamber. It acts as both a mechanical mount and a sealing interface — keeping combustion gases from escaping past the injector while maintaining the alignment critical to a consistent spray pattern. When the holder is worn, cracked, or incorrectly seated, the result is poor combustion, loss of power output, and potential damage to surrounding engine components.
