The video demonstrates the assembly process of an ATI balancer for installation on an engine. The presenter shows how to align the AC pulley and secure it in place, adding assembly lube and anti-seize at specific points. They then proceed to install the balancer onto the crankshaft using a balancer installer tool to prevent the crank from rotating. The process involves using a crank bolt and torquing it to 235 foot-pounds, ensuring proper lubrication of the threads. The video emphasizes a star pattern torque sequence for tightening the bolt and concludes with the final steps to complete the installation process accurately.
