Primary Timing Chain Tensioner from the timing drive assembly at the front of the 2.0L four-cylinder AJ200 / AJ20P4 engine.

The tensioner bears against the tensioner blade on the slack run of the primary chain, taking up chain stretch and wear so that correct crankshaft-to-camshaft timing is held and chain slap is controlled throughout the rev range.

A worn or collapsed primary tensioner typically announces itself as a rattle from the front of the engine on cold start, before oil pressure builds. Because the chain, guides and tensioner wear as a set, the tensioner is normally renewed as part of a full timing chain overhaul rather than in isolation.

Frequently asked questions

What does the LR123811G timing chain tensioner do?
The LR123811G timing chain tensioner keeps the primary timing chain under correct tension on 2.0L four-cylinder AJ200 and AJ20P4 engines. It takes up slack so the chain stays accurately timed to the camshafts. OEM part made by FAI.
Which engines and models does this tensioner fit?
This tensioner fits the 2.0L four-cylinder AJ200 and AJ20P4 engines only, across the Range Rover Evoque L538 and L551, Range Rover L405, Range Rover Sport L494, Velar, Discovery 5, Discovery Sport and New Defender 2020 on. It does not fit V6 or V8 engines.
What are the signs a timing chain tensioner is failing?
A failing tensioner on these 2.0L AJ200 engines typically shows as a rattle from the timing cover on start-up or a chain that has gone slack. If ignored, chain slap can let the timing jump. It is usually replaced whenever the timing chain is done.
Where is this tensioner located on the engine?
The timing chain tensioner sits inside the timing cover on the 2.0L AJ200/AJ20P4 engine, bearing against the primary chain that drives the camshafts. Access typically means removing the timing cover, so it is usually a specialist job done alongside a chain replacement.
