The injector clamp stud is a threaded fastener used to secure the injector hold-down clamps onto the cylinder head of 200Tdi and 300Tdi diesel engines. It anchors the clamp that retains each fuel injector in its bore, maintaining correct seating pressure and preventing combustion gas leakage past the injector seat. Worn, corroded, or snapped studs are a common failure on high-mileage Tdi engines and should be replaced before refitting injectors during any injector service. Key Features Threaded stud designed to accept the injector clamp retaining nut on 200Tdi and 300Tdi cylinder heads Direct replacement for the original fitment stud - no modification required during installation Meets OEM specification for thread pitch and length as used across Tdi engine variants Each injector requires one stud - check all studs for thread damage or corrosion when servicing injectors, and replace as a set where possible Vehicle Fitment Fits Defender (1986–2006), Discovery 1 (1989–1998), and Range Rover Classic, all with 200Tdi or 300Tdi engines.
