Multiquip DZ103065 DEF Tank - OEM Replacement Part for WhisperWatt Generators

The DEF (Diesel Exhaust Fluid) tank stores and supplies urea solution to the selective catalytic reduction (SCR) system on emissions-compliant diesel generators, enabling them to meet EPA Tier 4 Final standards. This tank is a critical emissions control component that must maintain proper fluid capacity and integrity to prevent engine derating or shutdown conditions.

Designed specifically for Multiquip's WhisperWatt Super Silent generator series, this OEM DEF tank integrates with the emissions control system on John Deere-powered units. The tank includes mounting hardware provisions and sensor interfaces required for proper DEF level monitoring and delivery to the SCR catalyst system. A damaged or leaking DEF tank can trigger fault codes, reduce engine performance, and lead to costly compliance issues in regulated environments.

Compatible generator models:

• DCA70SSJU4F (John Deere 4045HFG04 engine)

This genuine Multiquip OEM part ensures proper fit, emissions compliance, and reliable operation. Sold by an authorized dealer.
