Land Rover Part Number: 4179611 - Timing Chain Tensioner
4179611 is a timing chain tensioner fitted to the lower timing gear of AJ V8 engines. It takes up slack in the primary timing chain to maintain correct chain run and rail alignment during engine speed changes, applying a controlled preload to reduce noise, limit chain stretch and help prevent the chain from skipping teeth on the sprockets. The unit is specified for the AJ V8 4.4 petrol and the 4.2 V8 supercharged applications listed below and is mounted on the engine timing cover as part of the timing gear assembly.
