Multiquip 8981579360 DEF Tank Bolt - OEM Replacement Part

This bolt secures the DEF (Diesel Exhaust Fluid) tank assembly on Multiquip super silent generator models equipped with Tier 4 Final emissions systems. Critical for maintaining the integrity of the DEF tank mounting system, this fastener ensures the tank remains properly positioned during operation and transport, preventing fluid leaks and system failures that would compromise emissions compliance and generator performance.

The DEF tank bolt is an essential component in the emissions control system of Tier 4 Final diesel generators. Proper torque and installation of this fastener is critical during routine maintenance, tank replacement procedures, or after any service work involving the DEF system. A failed or loose DEF tank bolt can lead to tank displacement, line damage, and potential DEF system malfunctions that will trigger engine derates or shutdowns.
