ENGINE UNIT


  1. CONSTRUCTION


    1. A roller chain with a 9.525 mm (0.375 in.) pitch is used.

    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 chain sub-assembly.

    3. The No. 1 chain tensioner sub-assembly is a ratcheting type with a non-return mechanism.

    4. To achieve excellent serviceability, the No. 1 chain tensioner assembly is constructed so that it can be removed and installed through a service hole in the timing chain cover sub-assembly.

    5. The No. 2 chain vibration damper is installed between the camshaft sprockets on the intake and exhaust sides, thus reducing the vibration of the chain sub-assembly between the camshaft sprockets on the intake and exhaust sides when the engine is running, and ensuring that the engine is quiet and reliable.

    6. The No. 1 chain tensioner sub-assembly is installed on the lower side, thus the engine is more compact.

    7. Resin with excellent abrasion resistance is used on the shoes of the chain tensioner slipper, No. 1 chain vibration damper, and No. 2 chain vibration damper.

    8. A gasket (chain tensioner gasket) is used for the No. 1 chain tensioner sub-assembly, improving the oil retention of the oil collector, and thus suppressing the action of the chain when the engine is starting. This makes the engine quieter.
