crankshaft pulley change

can anyone tell me how to change the crankshaft on a 97 transport

Do you want to remove the pulley or the crankshaft. If you want to remove the pulley then remove the serpentine belt, remove the bolts holding the pulley in place and remove the pulley. Hand tools are required but it is not hard to change. Depending on the engine you will need to remove the bolt that holds the harmonic balancer in place. This will be tight and may require a breaker bar or impact wrench to remove it. You may want to purchase Chiltons or Haynes manual to helo you with this.
