This unique tool has been developed to aid in the removal of the harmonic damper pulleys found on the DODGE 5.7 and 3.5 liter engines.
The space allowed to insert the puller leg through the pulley is too small for any conventional universal puller to work without grinding away all of its strength, then it still may not have the correct geometry to stay on the puller landings cast into the back side of the pulley.
