LR3/Disco 3
Secondary drive is provided by two short crossover chains, which transfer drive from the exhaust camshaft gears to the
inlet camshaft gears. The crossover drives are located at the rear of the RH cylinder bank and the front of the LH cylinder
bank. This allows for a much shorter and simpler run for the main camshaft drive belt at the front of the engine.
Each crossover chain is tensioned via an automatic chain tensioner, which acts directly on the chains via a guide rail. The
tensioners are located between the exhaust and inlet camshafts at the front or rear of the cylinder head, depending on the
cylinder bank.
