CAMSHAFT CONSTRUCTION [MZR 1.6]
id0110f6101300
• A cast iron, highly rigid 5-axis hole camshaft has been adopted to insure higher reliability.
• Camshaft endplay is regulated at the rear of the No.1 journal.
• Lubricating oil is supplied from inside of the camshaft to each journal.
• Additionally the cam lobe part is chill cast to improve wear resistance, and the width of the cam heel part is shortened to reduce weight.
• The enhanced smooth-finishing precision on the cam lobe contact surfaces enables reduced friction and improved quietness.
• There is an oil line supplying oil to the variable valve timing actuator located on the intake port side camshaft (front of camshaft).
