The insert bush coded K 27107 plays a critical role in the precise and stable mounting of the fuel injection valve in the ZV40/48 diesel engine. It acts as an intermediary sleeve, ensuring proper alignment and seating of the injection valve within the cylinder head. Designed to absorb mechanical stress and prevent wear between metallic surfaces, this component contributes to long-term sealing integrity and consistent fuel delivery. Made from heat- and pressure-resistant materials, it supports the injector’s function under high thermal loads and guarantees reliable engine performance across long maintenance intervals.
