GMC Sierra Harmonic Balancer

The GMC Sierra Car model features the Harmonic Balancer which assists in balancing the engine and decreases the torsional distortion and vibration of the crankshaft. Composed of a hub normally made of metal, an inertia ring which is made of steel, and a rubber ring, the Harmonic Balancer's role is to minimize any twisting that may be exhibited by the crankshaft. Throughout time elements such as heat, road salt, and other fluids such as oil can affect the rubber and lead to damage to the engine. Standard OE balancers are intended for the factory set engines, though the performance balancers are available for heavily modified engines with an RPM protection. These performance balancers range from the conventional one with the construction of steel to the viscous fluid balancer and the multi-piece type with safety standards of high RPMs met or exceeded.

Each OEM GMC Sierra Harmonic Balancer we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.

GMC Sierra Harmonic Balancer Parts Questions & Experts Answers

  • Q: How to remove and install a vibration damper on 4.3L V6 engine on GMC Sierra?
    A: Disconnect the cable from the negative terminal of the battery. Remove the engine cooling fan, then remove the engine drivebelt. Remove the bolts and separate the crankshaft pulley from the harmonic balancer. Remove the large harmonic balancer-to-crankshaft bolt. To keep the crankshaft from turning, remove the starter and have an assistant wedge a large screwdriver against the ring gear teeth. A chain or strap wrench can also be used to secure the balancer. Using the proper puller, detach the harmonic balancer from the crankshaft. Be careful not to lose the Woodruff key. Make a written note of any weights used in the balancer, their locations, and lengths. These weights must be installed in exactly the same way when the balancer is installed. If a new harmonic balancer is being installed, transfer the weight(s) to the new balancer in the proper location(s). Make sure the woodruff key is in place, then position the harmonic balancer on the crankshaft and slide it on as far as it will go. Use a small dab of RTV sealant on the keyway of the balancer before installation. Note that the slot (keyway) in the hub must be aligned with the Woodruff key at the end of the crankshaft. Using a harmonic balancer installation tool, press the balancer onto the crankshaft. Note that the crankshaft bolt can also be used to press the crankshaft balancer into position, but when doing so, use a liberal amount of clean engine oil on the bolt threads to prevent galling. Make sure the raised crown of the balancer bolt washer is away from the crankshaft. Tighten the crankshaft bolt to the torque specifications. The remainder of installation is the reverse of removal.
  • Q: How to install a crankshaft balancer on V8 engine on GMC Sierra?
    A: Disconnect the cable from the negative terminal of the battery. Raise the front of the vehicle and support it securely on jackstands, then apply the parking brake. Remove the drivebelt, cooling fan, and shroud assembly. Working under the vehicle, remove the stone shield from below the engine if equipped. Remove the starter motor. Have an assistant wedge a large screwdriver or prybar into the driveplate ring gear teeth, then loosen the harmonic balancer pulley center bolt. Pull the balancer off the crankshaft with a puller. Position the harmonic balancer pulley/balancer on the crankshaft and slide it on as far as it will go. Using the harmonic balancer installation tool, press the harmonic balancer pulley/balancer onto the crankshaft. Install the old harmonic balancer bolt and tighten the crankshaft bolt to the proper torque specifications. Remove the old bolt and measure the distance from the snout of the crankshaft to the balancer hub. When properly installed, the balancer hub should extend 3/32 to 11/64-inch past the crankshaft snout. If the measurement is incorrect, reinstall the balancer installation tool and press the balancer on the crankshaft until the measurement is correct. Install a new harmonic balancer bolt and tighten it to the torque and angle of rotation specifications. The remainder of installation is the reverse of removal.
