Crankshaft Bearing and Crankshaft Bearing

► The crankshaft bearing is made of aluminum alloy.

► Similar to the connecting rod bearings, the lining surface of the crankshaft bearings is micro-grooved to realize an optimal amount of oil clearance. As a result, cold-engine cranking performance is improved and engine vibration is reduced.

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

► The crankshaft bearing caps are tightened using 4 plastic-region tightening bolts for each journal. In addition, each cap is tightened laterally to improve its reliability.
