Hence, the pulling of the crankshaft is balanced by the harmonically balancing ensures steady working of the engine and the elimination of certain dangers. Chevrolet Corvette has used different varieties of harmonic balancer such as conventional, viscous fluid and even multi-part tunable designs. For factory tuned engines, standard original equipment balancers are provided, however, performance harmonic balancers can be purchased for modified Corvettes to give protection against higher vibrations at higher RPM levels. These performance options are thoroughly endorsed to meet the performance standards especially where the weather condition is a constrain.

A:
The installation and removal of the Harmonic Balancer requires these tools: vehicle maintenance requires the Harmonic Balancer remover (J 41816) and the crankshaft end protector (J 41816-2) along with the Flywheel holding tool (J 42386-A) and both Harmonic Balancer and sprocket installer (J 41665) and torque angle meter (J 36660-A). Harmonic Balancer remover (J 41816), crankshaft end protector (J 41816-2), Flywheel holding tool (J 42386-A), Harmonic Balancer and sprocket installer (J 41665), and torque angle meter (J 36660-A). Start by taking off the right transmission cover and bolt before checking that the Flywheel holding tool (J 42386-A) teeth fit properly with the engine Flywheel. Fasten the j 42386-a component through one m10-1.5 x 120 mm and one m10-1.5 x 45 mm bolt until torque reaches 50 nm (37 ft. Lbs.). Keep the Harmonic Balancer bolt handy since you'll reinstall it during the process.
