  Q: How to service and repair the Harmonic Balancer on Ford E-250?

  A:

  You need to start by placing the vehicle into neutral gear on a hoist before removing the fan together with the fan shroud from the engine. The clockwise rotation of the tensioner apparatus allows the accessory Drive Belt to escape from the crankshaft pulley. Torque-to-yield specifications of the crankshaft pulley bolt make it unusable for reinstallation so ignoring this rule will lead to possible engine damage. A strap wrench will remove the crankshaft pulley bolt with its washer along with discarding the bolt. A crankshaft vibration damper remover implements the necessary steps to separate the crankshaft pulley from other parts. The installation process requires removing the unwrapped sealant if it remains unsecured for 4 minutes while performing cleaning procedures that include silicone gasket remover application and metal surface prep and waiting for complete drying. Seal the Woodruff key slot on the crankshaft pulley with silicone gasket and apply clean engine oil as the sealing fluid over the same area. A crankshaft vibration damper installer should be used for installing the crankshaft pulley. Users must implement a new crankshaft pulley bolt and washer when servicing the 4.6L (2V) engine while using a strap wrench to hold the pulley and tightening the bolt through four stages that start at 120 Nm (89 lb-ft), shift to loosening one full turn, continue at 50 Nm (37 lb-ft), and complete with an extra 90 degrees of tightening. The installation of the crank pulley bolt on the 5.4L (2V) engine requires initial tightening to 90 Nm (66 lb-ft) followed by turning the bolt one complete revolution and final tightening to 50 Nm (37 lb-ft) and additional 90 degrees. Common procedure follows the securement of the crankshaft pulley that requires rotating the tensioner clockwise then putting the accessory drive belt on the crankshaft pulley before you attach the engine cooling fan and fan shroud.
