The 1993 Chevrolet Camaro is a fourth-generation Camaro, which includes the 1993 through 2002 models. The Z28 performance package for these vehicles includes an LT1 engine, which has eight cylinders and a displacement of 5.7 liters. The LT1 engine in a 1993 Camaro has a harmonic balancer, or crankshaft balancer, to reduce the harmonic vibrations that occur when the crankshaft spins rapidly. The crankshaft balancer on the LT1 engine is a weight on the crankshaft hub.
Tools Used: Tools, Socket wrench set, Floor jack, Jack stands, Pry tool, Torque wrench
Replace Harmonic Balancer
Remove the battery cable from the negative terminal with a socket wrench to avoid starting the engine accidentally. Raise the vehicle on a floor jack, and support it safely on jack stands. Disconnect the serpentine drive belt from the crankshaft pulley with a socket wrench. Hold the hub of the crankshaft in place by using a straight piece of metal as a pry tool. Remove the retaining bolts from the hub with a socket wrench, and detach the crankshaft balancer from the crankshaft hub.
Mount the new crankshaft balancer onto the crankshaft hub, and fasten the retaining bolts for the crankshaft balancer. Hold the crankshaft hub in place with the pry tool, and tighten the retaining bolts for the crankshaft balancer to 63 foot-pounds with a torque wrench. Mount the serpentine drive belt on the crankshaft pulley, and lower the vehicle with a floor jack. Connect the cable to the negative battery terminal.
