constant on 2 ring, 3 ring and serpentine dampers. Typical 3 ring dampers
are 1.2" wide, 3 ring dampers are 1.5" wide. External balance units are
typically 1.8" wide. Degree Marks All units are fully degreed in 1° increments, 360° on micro-processor-controlled laser equipment. Pulley Mounting Most units have 3 Chevy mounting holes, 3/8-16 on a 3.200" bolt circle for pulley mounting except OEM Chrysler, OEM 3 bolt Fords and 4 bolt Small Block Fords. Most crank hubs have a protruding diameter to locate the OEM pulley. The protruding diameters are listed below: |

3 bolt Fords require pulley holes to be enlarged to 1/2" All units have a 4.750" register diameter for locating the Moroso/Truppi style Big Block trigger wheels. Balancing Internal Balance Internal Balance units have each part of the damper accurately balanced to 1/10 oz.in. before assembly. These units SHOULD NOT be on the crank for balancing as the inertia weight may not be centered until the engine starts. External Balance External balance GM 400 and 454 are identically balanced to GM service balance specifications. The hub and weight only should be installed for crank and balance. Since all hub/weights are identically balanced, ATI offers a slip fit hub and weight assembly for both the 400 and 454 allowing you to balance before pressing the damper on the crank. Replacing a damper on a previously balances engine in all applications requires match balancing the Super Damper to the existng damper unless the previous damper was an unaltered ATI unit. ATI can match balance a Super Damper to your existing unit accurately and promptly. Options For a damper without degree marks order Part #918520 with the appropriate damper Part # For a chrome damper (steel shell only) order Part #918500 w/the appropriate damper Part # Hubs Many hubs are available that are not listed. In most cases, custom hubs can be designed and manufactured promptly to suit your needs. Call us for details at 603-378-0090. |
