Multiquip M3424700104 DEF Tank Cover - OEM Replacement Part for Super Silent Generators

The DEF tank cover provides critical protection for the diesel exhaust fluid tank on Multiquip super silent generators, preventing contamination and managing airflow around the DEF storage system. This component was specifically redesigned as part of Multiquip warranty campaign GSP20170818 to include an integrated rubber flap that blocks and diverts incoming hot air from reaching the DEF fluid inside the tank, preventing premature degradation of the diesel exhaust fluid. The cover plate ensures proper DEF system operation on units equipped with 29.7-gallon (112.4-liter) DEF tanks running ultra-low sulfur diesel fuel.

This OEM cover is engineered for the DCA220SSJU4F and DCA300SSJU4F generator models, addressing a critical thermal management issue identified in field service bulletins. Proper DEF tank protection is essential for maintaining emissions compliance and preventing costly DEF system failures in Tier 4 Final diesel generators.

Compatible Models:

• DCA220SSJU4F
