Purpose and compatibility

The offered starter motor is a component from the Starter Motors group, dedicated to the starting system in the Land Rover Discovery 4 L319 with a 3.0 Diesel 306DT engine. Using a part from the same design line as the original allows for maintaining proper interaction with the vehicle's electronics, battery installation, and factory mounting points. The starter motor is adapted for operation in a diesel-powered system, which means it features appropriately selected gear ratios, starting torque, and operating characteristics matched to the higher compression resistance typical of diesel engines.

Technical and functional characteristics

The starter motor for the Discovery 4 L319 has been designed as a component with stable, repeatable torque, enabling efficient starting of the 3.0 Diesel 306DT unit on both cold and warm engines. The construction based on OEM solutions ensures:

• proper fitment to the engine housing and flywheel ring gear,
• compatibility with factory wiring and electrical connectors,
• operating parameters adjusted to the loads typical of diesel units. As a result, the starter motor can be used as a replacement for the factory-installed component without the need for any modifications to the starting system.

Condition, origin, and service application

The presented starter motor is a used component, which in practice means the possibility of an economical repair of the starting system while maintaining the original assembly specifications. For workshops and individual users, this is a beneficial service solution, allowing for cost reduction while maintaining compliance with factory Land Rover standards. The starter motor will prove effective both for typical replacement of a worn-out part and for major service work within the 3.0 Diesel 306DT engine, where maintaining the original geometry and operating parameters of the starting system is required.

Benefits of using an original Land Rover starter motor

Using a starter motor designed specifically for the Discovery 4 L319 brings a number of practical benefits:

• Factory fitment – compatibility with mounts, the flywheel ring gear, and the vehicle's electrical installation.
• Consistent starting parameters – operating characteristics adjusted to the 3.0 Diesel 306DT engine, which reduces the risk of starting issues.
• Cost-controlled service solution – a used OEM component allows for repair without the need to resort to universal replacements with uncertain parameters. This approach is particularly important in Land Rover class vehicles, where starting stability has a direct impact on operating comfort both off-road and during long journeys.
