Match the engine family, crank snout and keyway, balance type, hub, outside diameter, belt grooves, accessory drive, and every application note. The stated configuration is 7.074in - Alum - Chrysler B V8 - 361-440 - OEM Frt - 2 Ring.
Is this ATI Super Damper rebuildable?
ATI Super Dampers are serviceable. Inspect the shell, hub, fasteners, timing marks, and elastomers according to the current ATI instructions and service intervals.
Do I need a special installer for this damper?
Use the correct crankshaft damper installation tool and the exact fastener, washer, spacer, key, hub, and torque procedure for the engine. Never hammer the damper onto the crankshaft.
Installation Instructions
Use the current ATI instructions and the engine manufacturer's service information. Verify crankshaft and hub condition, key and spacer placement, required installer, fastener and washer, runout, pulley alignment, belt routing, clearances, and final torque. Never draw the damper on with an undersized or partially engaged bolt.
