  Q: How to replace the harmonic balancer on Cadillac Escalade EXT?

  A:

  You need to acquire the following tools to replace the crankshaft balancer: crankshaft balancer remover (J 41816), crankshaft end protector (J 41816-2), Flywheel holding tool (J 42386-A) and crankshaft balancer and sprocket installer (J 41665) and angle meter (J 45059). If equipped with air conditioning start by removing its Drive Belt yet accessory drive belts should be removed from vehicles without an air conditioning system. Starting the replacement process involves removing both the lower Fan Shroud alongside the Starter motor from the vehicle. The Flywheel holding tool (J 42386-A) requires its teeth to fit properly with the engine Flywheel teeth but individual balance work on the crankshaft balancer means it does not need any pre-removal markings. Screw in the Flywheel holding tool (J 42386-A) using two bolts of m10-1.5 x 120 mm and m10-1.5 x 45 mm types until they reach a torque of 50 nm (37 ft. Lbs.). The crankshaft balancer bolt needs removal because it will return for installation. The crankshaft balancer remover (J 41816) combined with crankshaft end protector (J 41816-2) will aid in removing the balancer and cleaning it before inspection if required. The first step of installation includes setting the crankshaft balancer directly on the crankshaft followed by using the crankshaft balancer and sprocket installer (J 41665) to complete the process. Attach the threaded rod together with the nut and washer and introduce the smaller end of the installer across the balancer front before achieving proper installation onto the crankshaft by tightening the nut. After reversing the installation tool you should tighten it until the balancer has finished installing. Install the old crankshaft balancer bolt with 330 nm of torque (240 ft. Lbs.) after which the bolt needs to be removed. The crankshaft nose needs to reach 2.4-4.48 mm (0.094-0.176 inch) of recess depth inside the balancer bore. Reinstall as needed. The installation begins by adding a fresh crankshaft balancer bolt which receives an initial torque of 50 nm (37 ft. Lbs.) before the meter (J 45059) indicates 140 degrees. The technical steps conclude with removing the Flywheel holding tool (J 42386-A) and bolts and installing the Starter motor before reinstalling the lower Fan Shroud along with the accessory Drive Belt (if A/C is not present) and the a/c Drive Belt (if A/C is present) followed by performing the crankshaft position (CKP) system variation learn procedure.
