Land Rover Part Number: 1025408 - Timing Chain Guide
1025408 is a timing chain guide for the 4.0 Cologne V6. Fitted to the balance-shaft and drive system, the guide locates and supports the timing chain and sets the running line where the chain routes around balance-shaft and drive components. Positioned along the chain run, it stabilises the chain under tension from the chain tensioner and resists lateral movement that would allow chain-to-component contact. Wear or breakage of the guide can permit chain slack, increased noise, accelerated wear of the chain and sprockets, and in severe cases timing deviation that may damage valves and pistons. Replacement of a worn guide prevents further damage to the timing system; fitment must match the engine and VIN requirements for Discovery 3 and Discovery 4 applications equipped with the 4.0 Cologne V6.
