How to align the timing marks on the Highlander 2.7 balance shaft?
1 Answers
First, rotate cylinder 1 to top dead center (TDC), then align the dot on the balance shaft gear. The balance shaft has a self-weighting force - rotate it to a specific angle for installation. Balance shaft technology is a simple yet highly practical engine technology that effectively reduces vehicle vibration and improves driving comfort. Common causes of loose balance shaft bearings and abnormal wear on bearing seats include poor engine balance and restricted movement of the rolling bearings.
