Land Rover Part Number: 4174187 - Timing Chain
4174187 is a timing chain fitted as the upper (secondary) timing drive on AJ Petrol 4.4 V8 EFI and AJ Petrol 4.2 V8 Supercharged engines. It transmits crankshaft rotation to the camshafts and runs with the upper sprockets, tensioner and guide components to maintain correct camshaft phasing for intake and exhaust valves. Wear or elongation in the chain will alter cam timing and can cause running irregularities or valve-timing interference; when replacing the chain, inspect and typically renew associated tensioners and guides to restore correct alignment and tension.
