Deutz FL511 Control Spring 0223 3665 China Exporter for Diesel Governor Engine Repair

The Deutz FL511 Control Spring 0223 3665 regulates governor feedback within FL511 diesel injection pump assemblies. Over time, heat cycling and mechanical wear reduce spring tension, leading to speed hunting, rough idle, or inaccurate fuel metering. Replacement is normally carried out alongside injection pump service, governor recalibration, or complete fuel system overhaul. As a China exporter and factory-direct供货商, we provide this control spring to fuel injection specialists, diesel service centers, and aftermarket parts distributors serving Deutz-powered generator sets and industrial engines. Our approach centers on production-sourced consistency, correct tension specification, and export-ready packing, offering buyers a practical alternative to OEM-priced fuel system components. The 0223 3665 control spring is available for bulk and mixed export shipments.
