Timing Chain and Chain Tensioner

VVT-i Controllers

► Both the primary and secondary timing chains use roller chains with a pitch of 9.525 mm (0.375 in.).

► The timing chain is lubricated by an oil jet.

► The primary chain uses one timing chain tensioner and each of the secondary chains for the right and left banks uses one timing chain tensioner.

► Both the primary and secondary chain tensioners use a spring and oil pressure to maintain proper chain tension at all times. They suppress noise generated by the timing chains.

► The chain tensioner for the primary chain is the ratchet type with a non-return mechanism.
