CAMSHAFT CONSTRUCTION [LF, L5]

• The 5 journal which has high 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 lobe part is chill-casted to improve the abrasion resistance, and the width of cam heel part is shortened to reduce the weight.
• There is 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.
• There is an oil line, by which the oil is supplied to the variable valve timing actuator located at the intake port side camshaft (front of camshaft).
