How to Install an LT1 Harmonic Balancer

General Motors manufactured its modern LT1 engine from 1992 to 1997. This eight-cylinder 5.7-liter engine appears in many high-performance cars from General Motors during this period, such as the Chevrolet Corvette. The harmonic balancer, or crankshaft balancer, in the LT1 engine is a disc-shaped weight on the end of the crankshaft. Its function is to stabilize the rotation of the crankshaft, which prevents the crankshaft from failing at speeds.

Instructions

1

Disconnect the cable from the negative battery terminal with a socket wrench. This prevents anyone from unintentionally starting the engine. Remove the air intake duct from the engine to access the crankshaft.

2

Raise the vehicle, and support it on jack stands. Disconnect the nuts from the engine mount with a socket wrench. Remove the cooler for the power steering fluid from the engine compartment.

3

Place a screw jack under the engine, and raise the engine slightly to access the crankshaft balancer. Remove the retaining bolts for the crankshaft balancer with a socket wrench. Attach a puller to the crankshaft balancer, and pull the balancer from the crankshaft.

4

Mount the new crankshaft balancer to the crankshaft, and tighten its mounting bolts to 60 foot-pounds with a torque wrench.

5

Lower the engine with the screw jack, and connect the cooler for the power steering fluid with a socket wrench. Fasten the nuts for the engine mount to 40 foot-pounds with a torque wrench. Lower the vehicle with the floor jack. Connect the air intake duct and negative battery cable.
