Corvette V8-5.7L VIN G (1997)
Off-Vehicle Balancing
Use a balancer which pilots the wheel by the center hole (not the wheel stud holes). Follow the equipment manufacturer's instructions.
Some electronic off-vehicle balancers are more accurate than the on-vehicle spin balancers. Do not correct for rotor unbalance. If the vibration is not
corrected by the off-vehicle balance, perform a on-vehicle balance.
On-Vehicle Balance
1. Do not remove the wheel weights added from the electronic off-vehicle balance.
2. Split the new on-vehicle weights equally between the inner and outer rim flanges of the wheel to avoid disturbing the dynamic balance from the
electronic off-vehicle balancer.
3. Follow the equipment manufacturer's instructions.
Wheel Balance Weights
Important: Install the coated weights with care to prevent the polyester coating from cracking. Use a nylon or plastic tipped hammer during installation
of the coated weights.
Use special polyester coated clip-on wheel balance weights to balance aluminum wheels. The weights are designed to fit over the thicker inboard and
outboard rim flanges of the aluminum wheel. The following advantages are provided with the use of the special polyester coated clip-on wheel balance
weights:
-
The weights provide a better appearance.
-
The weights will not discolor.
-
The weights will not corrode.
-
The weights will not damage the wheel.
Magnesium Wheel (Export Only)
The magnesium wheel rim flange (1) is not designed for use with clip-on weights. The magnesium wheel requires the use of special adhesive backed
balance weights (2). The color of the adhesive balance weight should be matched to the color of the wheel.
Use an off-car dynamic balancer to balance the wheel and tire assemblies. Place the wheel on the balancer so that the center pilot hole is located by a
cone or hub through the backside of the wheel. Use a flange plate with fingers for each wheel stud hole to clamp the wheel to the machine. If a flange
plate is not available, a pressure cap may be used. Be careful that the pressure cap does not mar the face of the wheel.
The following must be performed before applying the adhesive balance weights:
1. Clean the wheel surface with alcohol and dry.
2. Select the correct color of the adhesive balance weight.
