This is a genuine Nissan double-row timing chain designed as a direct replacement for Nissan Navara D22, D40, and Pathfinder R51 models equipped with the YD25 engine. Located inside the front of the engine, the timing chain is a critical component that synchronises the rotation of the crankshaft and camshafts. This specific chain is the upper, double-row version which connects the idler sprocket to the two camshaft sprockets.
Over time, the original timing chain can stretch and wear, which can negatively affect engine timing, performance, and in the worse can lead to pistons hitting valves. Replacing a worn or stretched chain is essential for maintaining correct engine operation and preventing further internal damage.
Please note: Replacing a timing chain is a complex task that requires significant engine disassembly and specialised tools. To ensure a comprehensive and reliable repair, it is highly recommended to also replace the chain tensioners, guides, sprockets, and seals at the same time.
