Good morning
Do not use the harmonic balancer bolt to "drawing - in" the BHJ. Assuming you have a new BHJ balancer the inside diameter must be milled to accepted the specific outside diameter of the the crankshaft snout. Because of the tight fit press unit, "drawing - in" procedure will increase the chance of ruining the crankshaft snout threads and or not seating the balancer. Striking it with a hammer will damage it also. Try Auto Zone, O'reilly, and or Advance Auto for the installation tool to purchase or rent.
Good Luck.
