ENGINE UNIT DETAILS TIMING CHAIN AND CHAIN TENSIONER

  1. CONSTRUCTION

    1. A high-strength roller chain with an 8 mm (0.315 in.) pitch is used to make the engine more compact and to ensure the reliability of the timing chain (chain sub-assembly).

    2. The No. 1 chain tensioner assembly uses a spring and oil pressure to maintain proper chain tension at all times. The No. 1 chain tensioner assembly suppresses noise generated by the timing chain (chain sub-assembly).
