Land Rover Part Number: 4179614 - Timing Chain Tensioner
4179614 is a timing chain tensioner fitted to the lower timing gear of AJ Petrol 4.4 V8 EFI (220KW) engines. It applies and holds the required tension on the timing chain to limit lateral movement and excessive slack that can lead to accelerated wear, timing drift or the chain jumping teeth on sprockets. The tensioner operates as part of the timing gear system and works with the timing chain, guides and sprockets to maintain consistent chain engagement under varying engine loads and temperatures. When replacing this item, inspect the timing guides and the chain for wear, since worn guides or a stretched chain will reduce the effective life of a new tensioner. Fitted applications include Discovery 3, Range Rover and Range Rover Sport models equipped with the AJ Petrol 4.4 V8; Range Rover applications may also list fitment for AJ Petrol 4.2 V8 Supercharged lower timing gear.
