• Q: How to replace the harmonic balancer on 2007 GMC Envoy?

  A: Begin the crankshaft balancer replacement by removing the cooling fan together with the shroud after the Drive Belt has been removed. Slots and removes the balancer bolt while you insert the crankshaft end protector (J 41816-2) into the crankshaft's final position with a warning to avoid pulling on the balancer's outer edge. A 3 jaw puller should be used to detach the crankshaft balancer and afterward remove both the puller and j 41816-2. The crankshaft balancer shim should be taken off of the crankshaft snout for cleaning before performing an inspection of the crankshaft balancer. After raising the vehicle you must remove the torque converter access plug from the dry region of the Oil Pan. The torque converter holding tool from the crankshaft balancer remover/holder (J 44226) kit enables secure torque converter attachment when tightening the crankshaft balancer. Insert the new crankshaft balancer shim gm p/n 12573950 over the crankshaft snout to face the Crankshaft Gear. Afterwards, install and seat the crankshaft balancer using the crankshaft front oil seal installer (J 41478). The installer should hold the Flywheel steady before installing the balancer washer and bolt. Tighten the crankshaft balancer bolt to 150 n.m (110 lb ft) while subsequently using the torque angle meter (J 36660-A) to finish with an additional 180 degrees of bolt torque. The last step involves discarding the torque converter holding tool before reinstalling the torque converter access plug back into the Oil Pan. The vehicle needs to be lowered afterward which requires installing both the Drive Belt and cooling fan and shroud.
