How to replace the harmonic balancer on Cadillac Escalade?

The first step to replace a Crankshaft balancer requires removing the air conditioning Drive Belt and cooling fan and shroud and Starter motor with proper alignment of the j 42386-a (Flywheel Holding Tool) teeth to the engine Flywheel. Users must install the j 42386-a using one m10-1.5 x 120 mm and one m10-1.5 x 45 mm bolt before tightening them to 50 nm (37 lb ft). The Crankshaft balancer bolt (139) must be taken off for reinstall usage later on. This operation requires the purchaser to connect the j 41816 (Crankshaft Balancer Remover) and j 41816-2 (Crankshaft End Protector) to the Crankshaft balancer (138) before removing the component. Position the Crankshaft balancer onto the Crankshaft then use j 41665 (Crankshaft Balancer and Sprocket Installer) together with j 41478 (Crankshaft Front Oil Seal Installer)'s threaded rod for balancer installation. The balancer must be straight before tightening the Crankshaft balancer bolt (139) to 330 nm (240 lb ft) during the first bolt torque stage then continuing with the bolt removal process.

In Cadillac Escalade vehicles, the Harmonic Balancer has been designed to ensure the proper balancing of the engine as well as to absorb vibrations that are as a result of the combustion process. This component also known as a vibration damper made of metal with crankshaft in the middle of it and has an inertia ring, a rubber ring that either revolve or is free to flex in the plane perpendicular to the oscillating twisting force. As it helps maintain smooth operation of the engine, damage on the rubber may result to fatigue and may cause, excessive vibrations may lead to crankshaft damages. Currently, Cadillac Escalade has had the opportunity to incorporate different kinds of harmonic balancers ranging from the OEM types to the performance types. While the traditional standard balancer is meant for factory engine ratings, performance harmonic balancers are for tuned up automobiles giving better protection against elevated vibrations at fast revolutions per minute ratings. Among the performance options are traditional, viscous, and multi-piece models, all of which are safety-tested at high RPMs and have such features as 360-degree timing marks for engine tuning.
