Starter Generator Drive Belt - belt drive for the belt-integrated starter generator on 3.0L Ingenium six-cylinder mild-hybrid (MHEV) engines, petrol (AJ20P6) and diesel (AJ20D6).

Runs between the crankshaft pulley and the starter generator pulley and carries torque in both directions: the starter generator turns the crankshaft to restart the engine and to add torque assist, and the crankshaft drives the generator when recuperating energy into the mild-hybrid battery. That reversing load is why it is a dedicated drive rather than part of the ancillary accessory belt run.

Glazing, rib cracking or slip typically shows as rough or slow stop/start restarts and hybrid system fault messages.

Frequently asked questions

What is the LR180546LR drive belt for?
The LR180546LR is a drive belt for the belt starter generator on 3.0 litre MHEV mild hybrid engines. It links the starter generator to the crankshaft, allowing smooth engine restarts and energy recovery in the mild hybrid system.
Which vehicles does this MHEV drive belt fit?
This belt fits 3.0 litre AJ20 MHEV New Defender L663, Discovery 5, Range Rover L460 (2022 on), Range Rover Sport L461 (2023 on) and Range Rover Velar, in petrol and diesel versions. Each model has a VIN range, so confirm your chassis number falls within it.
What are the signs the starter generator belt needs replacing?
A worn belt starter generator drive belt often squeals, cracks, or causes rough or slow engine restarts on MHEV models. Because it drives the mild hybrid starter generator, a failing belt can trigger hybrid system warnings and should be replaced before it snaps.
