Land Rover Part Number: LR121792 - Timing Chain
LR121792 is a timing chain fitted to the timing gear of 3.0L AJ20P6 petrol engines. The chain transfers rotary motion from the crankshaft to the camshafts to synchronise valve opening and closing; it runs over guides and sprockets and works with tensioners specific to the AJ20P6 layout. Worn or elongated chains produce slack and audible rattle and, if left unaddressed, can allow valve timing to drift and risk valve-to-piston contact. Replacement chains restore correct mechanical timing - during installation the chain must be aligned to the engine timing marks and any associated tensioners or guides should be inspected and renewed if necessary to avoid premature wear of the new chain.

Frequently Asked Questions
The timing chain transfers rotary motion from the crankshaft to the camshafts to synchronise valve opening and closing on the 3.0L AJ20P6 engine. It runs over guides and sprockets and operates with tensioners to maintain accurate camshaft phasing; wear or elongation causes slack, noise and the potential for valve timing drift which can lead to valve-to-piston contact in interference engines. Replacement restores correct timing - ensure the chain is aligned to the engine timing marks and inspect associated tensioners and guides when fitting.
