Land Rover Part Number: 4361284 - Timing Chain Tensioner
4361284 is a timing chain tensioner for the 4.0 Cologne V6. Fitted in the balance shafts and drive area, this unit applies and maintains the correct running tension on the timing chain. It controls chain slack during changes in engine speed and load to reduce chain rattle and limit wear on sprockets and guides, helping to preserve valve timing stability and prolong the service life of the timing chain assembly. This part is used on Discovery 3 and Discovery 4 vehicles fitted with the 4.0 Cologne V6 engine, including Discovery 4 units from VIN AA000001. When fitting a replacement tensioner, inspect the chain guides and sprockets for wear, as a worn chain system can overload a new tensioner.
