CONSTRUCTION
A high-strength roller chain with a 9.525 mm (0.375 in.) pitch is used to make the engine more compact and to ensure the reliability of the timing chain.
The chain tensioner uses a spring and oil pressure to maintain proper chain tension at all times. The chain tensioner suppresses noise generated by the timing chain.
A ratchet type non-return mechanism is used in the chain tensioner.
