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 abrasion 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 to achieve reliability. Also, resin is used for the sliding portion of the chain, in consideration of abrasion 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 and low engine rotation.

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