@artem_pankovich: Mercedes OM642 - Timing Chain Installation | Marks, Tensioner & Guides. • Mercedes-Benz OM642 3.0 CDI - timing chain installation. • The engine rebuild continues with one of the biggest components of the OM642 timing system - the long and heavy timing chain. • A new timing chain, new guides, dampers and a new tensioner are installed. The original timing sprockets are reused because they show no significant wear. • The interesting part is setting the OM642 timing marks. The installation procedure is quite specific and requires following the correct sequence to position every component properly. • I’ll show the chain installation, timing marks, guides and tensioner step by step, including the sequence used during the assembly of the timing drive. • Another important stage of the Mercedes OM642 3.0 CDI rebuild - precise, detailed and focused on the actual repair process. • #supermechanik #artempankovich #carservice #goldenhandsmechanic #CarRepair
