Multiquip M5424600004 DEF Supply Door White - OEM Replacement Part for WhisperWatt Generators

The DEF Supply Door provides secure access to the Diesel Exhaust Fluid (DEF) supply system on Multiquip WhisperWatt Super Silent generators equipped with Tier 4 Final emission-compliant engines. This white exterior panel protects the DEF fill point while maintaining the generator's weather-resistant enclosure integrity. The door assembly is essential for routine DEF maintenance on John Deere 6068HFG08-powered units, which require regular monitoring and refilling to maintain emission compliance and prevent system shutdowns due to low DEF levels.

Designed specifically for the WhisperWatt Super Silent series, this genuine OEM door maintains the acoustic properties of the sound-attenuated enclosure while providing quick access for fluid checks and refills. The white finish matches factory specifications for the DCA-SSJU4F generator family. Proper door function is critical for preventing contamination of the DEF supply and maintaining the Selective Catalytic Reduction (SCR) system performance required by EPA Tier 4 Final standards.

Compatible with the following Multiquip generator models:

• DCA150SSJU4F3
• DCA180SSJU4F3
