Multiquip 8941741410 Spring Nozzle Holder DCA-25USI 4LE2

The Multiquip 8941741410 Spring Nozzle Holder DCA-25USI 4LE2 is a genuine OEM component designed for the DCA25USI ultra-silent diesel generator series. As a direct OEM replacement, this part is sourced and specified to match the original component installed at the factory, ensuring a correct, trouble-free installation. Verified fitment for DCA25USI generators means you can order with confidence knowing this is the right part for your machine.

Key Features

• Genuine OEM Fuel System Integrity — Manufactured to the exact material and dimensional specifications of the original nozzle holder spring, maintaining proper injector seating force and fuel delivery consistency.
• Direct-Fit Replacement — Engineered to drop into the existing injector assembly on DCA25USI generators, matching original mounting points and spring geometry for a straightforward service swap.
• Confirmed DCA25USI Compatibility — Specifically validated for the DCA25USI ultra-silent diesel generator equipped with the Isuzu 4LE2 engine; eliminates guesswork when sourcing injector components.
• Consistent Injector Clamping Force — Maintains the correct spring tension needed to hold the fuel nozzle securely in position, supporting stable combustion and steady generator output.
• Fuel System Safety — A correctly tensioned nozzle holder spring prevents injector seat leakage and uncontrolled fuel weeping, which is critical for safe diesel engine operation in enclosed or sensitive environments.

The spring nozzle holder is a small but critical component within the diesel fuel injector assembly. It applies the precise clamping force required to seat the fuel nozzle correctly against its bore, ensuring the injector delivers fuel at the right pressure and spray pattern for clean, efficient combustion. When this spring weakens, loses tension, or fails entirely, the nozzle can shift or leak, leading to rough engine operation, increased emissions, hard starting, or fuel contamination of combustion chamber components.
