The timing drive uses four silent chains. The silent chain link design improves sprocket engagement and reduces noise,
vibration and harshness (NVH). One chain (5) drives the oil pump (4) and three chains drive the camshafts in a two stage
design. The left secondary camshaft chain (1) uses an oil pressure controlled chain tensioner (9) with a ratcheting device. The
right secondary camshaft chain (8) uses an oil pressure controlled tensioner (7) without a ratchet. The primary chain (2) also
uses an oil pressure controlled tensioner (6) without a ratchet. A spring loaded tensioner (3) takes up the slack in the oil pump
chain (5). The chain guides and tensioner arms are made of glass filled nylon with nylon wear faces
