Primary Accessory Drive Belt for the 5.0L AJ133 DOHC supercharged V8 petrol engine, forming part of the front end accessory drive.

The multi-ribbed serpentine belt transmits crankshaft torque to the engine ancillaries, including the alternator, air conditioning compressor and water pump. It is held under tension by the automatic belt tensioner and routed over the idler pulleys; the supercharger is driven by a separate secondary belt.

Replace the belt when the ribs show cracking, glazing or missing material, and check the tensioner and idler pulleys at the same time, as a worn tensioner will shorten the life of a new belt.

Frequently asked questions

What is the LR184639LR primary accessory drive belt for?
The LR184639LR is the primary accessory drive belt for the Defender 2020 (L663) with the 5.0L V8 supercharged petrol engine (AJ133). It drives the front-end accessories off the crankshaft and is separate from any secondary belt on the same V8 engine.
How do I confirm this belt fits my Defender V8?
The LR184639LR fits the Defender 2020 (L663) with the 5.0L V8 supercharged petrol engine (AJ133), Nitra plant build from VIN (V)M2000001. It doesn't fit the four-cylinder or six-cylinder Defenders, so confirm the V8 and check your VIN build.
When should the V8 accessory drive belt be replaced?
Replace the Defender V8 accessory drive belt when the ribs show cracking, glazing, or fraying, or if the belt squeals. A failed primary belt on the 5.0L supercharged V8 stops accessory drive, so inspect it if you hear noise from the front of the engine.
