BALANCING OR MATCH BALANCING
•
Each Fluidampr component is precision balanced during manufacturing, so NO additional balancing is required.
•
DO NOT ATTEMPT TO BALANCE THE CRANKSHAFT WITH FLUIDAMPR INSTALLED
- The inertia ring
inside Fluidampr is balanced to a close tolerance at the factory and it rotates inside Fluidampr.
•
If balancing the crankshaft is required, install the stock damper while balancing.
Step 1 – Stock Damper Removal
•
Remove any equipment or accessories obstructing access to the stock damper per manufacturer’s instructions.
•
Remove the accessory drive belt and A/C compressor drive belt.
NOTE
•
Remove the stock damper using a suitable puller. Save the stock damper crankshaft bolt to use during the
Fluidampr installation process.
-
There is no tensioner on the A/C belt. The belt will either have to be “walked” off of the pulley or cut and
replaced with a new belt.
•
On the rear of the stock damper hub you will find a thin metal washer held in place with a rubber gasket. This
washer will need to be removed and installed on the Fluidampr. If you don’t have a washer or the one you have is
destroyed one can be obtained thru your local GM dealer (ref GM P/N 12603843).
