ENGINE UNIT


  1. CONSTRUCTION


    1. The chain sub-assembly uses a 9.525 mm (0.375 in.) pitch high-strength roller chain, and the No. 2 chain sub-assembly uses a 8.000 mm (0.315 in.) pitch high-strength roller chain, reducing friction.

    2. Resin is used for the chain slipper and chain damper, reducing friction and increasing wear-resistance.

    3. A timing chain guide is provided between the intake camshaft and exhaust camshaft to suppress vibrations in the chain sub-assembly and improve quietness and reliability. Also, resin is used for the sliding portion of the chain, in consideration of wear-resistance.

    4. The chain tensioner uses the spring and oil pressure to always maintain appropriate tension in the chain sub-assembly and No. 2 chain sub-assembly, ensuring quietness and reliability. Also, the chain tensioner uses an internal oil retention mechanism and a ratchet mechanism to improve quietness when starting the engine.

    5. A chain tensioner gasket is used to improve oil retention, improving quietness when starting the engine.
