Timing Chain Guide, Lower Primary from the front timing gear assembly.

It bears against the primary drive chain on the run between the crankshaft sprocket and the upper timing gear, holding the chain on its intended path and damping the whip that would otherwise develop across the free span. A worn or cracked guide lets the chain slap, which accelerates chain and sprocket wear and can disturb valve timing.

For the 2.0L I4 Ingenium (AJ200 / AJ20D4) engine, petrol and diesel. The guide is secured by the timing gear special nut LR120542.

Frequently asked questions

What does the LR120540 timing chain guide do?
The LR120540 is the lower primary timing chain guide for the 2.0L Ingenium engine (AJ200/AJ20D4, diesel and petrol). It keeps the timing chain running true and tensioned along its lower run. A worn or cracked guide lets the chain slap, which can affect timing and cause rattle.
When should the timing chain guide be replaced?
The chain guide is typically replaced during a timing chain job or when the engine rattles on start-up on these 2.0L Ingenium engines. Guides wear and can crack with age. Most workshops fit new guides whenever the chain is off, since the labour to reach them is the same.
Which vehicles use this timing chain guide?
This guide fits the 2.0L Ingenium engine in the New Defender (2020 on), Discovery 5, Discovery Sport, Range Rover Evoque L538 and L551, Range Rover Sport L494, and Range Rover Velar. It covers both diesel and petrol Ingenium units. Confirm your engine is the 2.0 Ingenium.
