2009 Chevrolet Aveo Camshaft Parts and Q&A

• Q: How to service and repair the camshaft on 2009 Chevrolet Aveo?

  A: The first step when servicing or repairing the Camshaft starts with measuring its lift length which requires replacement if the measurement shows values other than 46.3 mm (1.8228 in). Each journal's outer diameter must be measured at four different spots because replacement is necessary if the diameter measures beyond the range of 27.939-27.960 mm (1.1000-1.1008 in). A dial gage measurement of the Camshaft straightness should be performed to determine replacement if values go beyond 0.04 mm (0.0016 in). A dial gage measurement of Camshaft endplay should be followed by Camshaft replacement if the recorded value exceeds 0.130-0.215 mm (0.0051-0.0085 in). Two measurements should be taken from different points on the Cylinder Head journal to check if it meets specifications of 28.000-28.021 mm (1.1024-1.1032 in). If not, the Cylinder Head needs replacement.
