Land Rover Part Number: LR072638 - Crankshaft Gear
LR072638 is a crankshaft gear fitted to the timing gear system on 3.0L DOHC GDI SC V6 and 5.0L AJ133 supercharged V8 petrol engines. Positioned at the front of the crankshaft, it transmits rotational motion into the timing assembly to drive chains or sprockets that set camshaft and other timing component positions; the correct tooth profile and material hardness are required to maintain timing accuracy and durability. The gear works with companion sprockets, tensioners and guides to maintain chain alignment and minimise slack; inspect the timing components where access allows and replace worn gears alongside other timing parts to preserve correct timing geometry.

Frequently Asked Questions
LR072638 transfers rotation from the crankshaft into the timing system, driving chains or sprockets that control camshaft timing on the 3.0L V6 and 5.0L AJ133 V8 engines. It must retain correct tooth form and hardness to avoid timing inaccuracies; common issues include tooth wear or damage and resultant chain slack. Inspect the gear whenever the timing assembly is accessed and replace it with companion sprockets, tensioners and guides if wear or damage is found.
