CAMSHAFT [L3]
BME011012420T02
Structure
• The cast iron 5 axis-hole, which has great rigidity, has been adopted for the camshaft to insure higher reliability.
• The endplay of the camshaft is regulated at the rear of the No. 1 journal.
• The lubricating oil is supplied through the oil supply hole at each journal. Additionally the cam nose part is chill casted to improve the abrasion resistance and the width of cam hill part is shortened to reduce the weight.
• There shall be no positioning pin or key slot for the camshaft sprocket at the edge of the camshaft. The lubrication process has been adopted for the camshaft sprocket tightening bolt to prevent instability in the axis during tightening.
