ENGINE UNIT DETAILS CRANKSHAFT AND BEARING

  1. CONSTRUCTION

    1. The crankshaft has 4 journals and 6 balance weights.

    2. All pins and journal fillets are roll-finished to maintain adequate strength.

    3. The crankshaft bearing is made of aluminum alloy.

    4. The lining surface of the crankshaft bearings are micro-grooved to realize an optimal amount of oil clearance. As a result, excellent cold-engine cranking performance has been realized.

    5. The upper main bearing has an oil groove around its inside circumference.
