Land Rover Part Number: NAD10040 - Starter Motor
NAD10040 is a starter motor for the 2.5 4 cylinder petrol engine fitted to Defender 90 and Defender 110 models. Fitted to the starter location on the transmission bellhousing, this unit converts electrical energy from the vehicle battery into mechanical rotation to crank the engine, engaging via a solenoid-driven pinion with the flywheel or ring gear. It interfaces with the vehicle wiring and solenoid switchgear specific to these Defender models. Replace the unit if it fails to engage consistently, produces grinding noises or draws excessive current; check electrical connections and mounting faces for corrosion and ensure fasteners are torqued correctly during installation.
