How to Remove an LT1 Balancer

The LT1 is an eight-cylinder, 5.7-liter engine that was installed in various General Motors vehicles from 1992 to 1997. For example, the LT1 was the standard engine in the Chevrolet Caprice, Camaro and Pontiac Firebird during this period. This engine requires a balancer, or damper, on the crankshaft to minimize the vibrations that can result from a rapidly-spinning crankshaft. The crankshaft balancer is a circular weight that fits on the crankshaft over the crankshaft hub.

Instructions

1

Remove the negative battery cable with a socket wrench to ensure you dont start the engine inadvertently. Disconnect the air intake duct from the engine to gain access to the crankshaft.

2

Place a floor jack under the front of the vehicle, making sure the jack is not under any sheet metal, such as the oil pan. Raise the vehicle and support it on jack stands. Disconnect the retaining nuts for the engine mounts.

3

Remove the cooler unit for the power steering fluid with a socket wrench to access the crankshaft.

4

Raise the engine slightly with a screw jack to access the crankshaft balancer. Remove the mounting bolts and screws from the balancer with a socket wrench.

5

Attach a suitable removal tool to the crankshaft balancer, and remove it from the crankshaft. Be sure to use a tool specifically designed for this purpose, rather than a universal claw. The wrong tool can break the bond between the crankshaft hub and its outer ring.
