Land Rover Part Number: ETC5172 - Camshaft Sprocket
ETC5172 is a camshaft sprocket fitted to the 2.25L 4-cylinder petrol engine used in Defender models. The sprocket mounts to the camshaft and transmits rotation from the timing chain to the camshaft, establishing valve timing; it works together with the timing chain, crankshaft sprocket and tensioning components to maintain synchronisation between crankshaft and camshaft. Replacement is typically required if teeth are worn or damaged, or if timing chain-related wear has allowed movement that can alter valve timing.

Frequently Asked Questions
ETC5172 is a camshaft sprocket that engages the timing chain and converts chain motion into camshaft rotation so the valves open and close at the correct points in the engine cycle. It works with the crankshaft sprocket, timing chain and tensioning components to maintain synchronisation. Common failure modes are worn or damaged teeth and timing chain-related wear that allows movement, which can alter valve timing; replace if such wear or damage is evident.
