Crankshaft Pulley

The engine cooling fan motor and shroud need to be deleted as the first step before servicing or repairing the harmonic balancer and crankshaft pulley. Follow these steps to remove the accessory drive belt from the tensioner as you rotate its mechanism clockwise. Then uninstall the crankshaft pulley bolt. The Crankshaft Vibration Damper Remover should be used to disconnect the crankshaft pulley. Use silicone sealant on the Woodruff key slot of the crankshaft pulley before installation and complete the procedure within 4 minutes of applying the silicone. The installation of the crankshaft pulley requires a Crankshaft Vibration Damper Installer which should be used along with a Strap Wrench for holding the pulley in position. The bolt installation process starts with tightening it to 120 Nm (89 lb-ft) and follows with a full turn relaxation then continuing to 50 Nm (37 lb-ft) until achieving an additional 90 degrees of torque. The first step after rotation of the tensioner is to reattach the accessory drive belt before reinstalling the engine cooling fan motor and shroud.

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.

Service and repair of the crankshaft pulley begins with setting the vehicle to NEUTRAL on a hoist. Start by taking out the cooling fan before using a clockwise motion to detach the accessory drive belt from the crankshaft pulley through the accessory drive belt tensioner. Press the position retaining tab while removing the pushpin to allow rotating the lower cooling fan shroud up until the position retainer tab secures into place. The first step for removing the crankshaft pulley consists of discarding both the crankshaft pulley bolt and its washer before using a 3-Jaw Puller device. Apply silicone gasket and sealant to the Woodruff key slot of the crankshaft pulley but if installation takes longer than 4 minutes the sealant should be removed while cleaning the sealing area with metal surface prep and silicone gasket remover before complete drying. You should use the Crankshaft Vibration Damper Installer to mount the new crankshaft pulley after that you must affix both the new bolt and only tighten it in four installation stages at 120 Nm (89 lb-ft) before loosening it 360 degrees then repeating at 50 Nm (37 lb-ft) before final tightening by 90 degrees. Push and rotate the lower cooling fan shroud downward until its position tab locks into the retainer and complete the assembly with the pushpin. Use the accessory drive belt tensioner to rotate it clockwise so the belt connects to the crankshaft pulley before adding the cooling fan shroud.

The process of harmonic balancer and crankshaft pulley servicing begins with removal of the timing chain followed by wire harness disconnection with proper placement and subsequent removal of the radiator fan assembly. The service starts with removing the engine dynamic balance shaft through bolt removal which allows detachment of the balance shaft driver gear and thrust plate while separating the engine dynamic balance shaft into an assembly. When installing the engine dynamic balance shaft assembly into the cylinder block position the camshaft at 12 o'clock before alignment of the timing marks between the engine balance shaft drive gear and the engine balance shaft driven gear. When installation is perfect the timing marks on both the engine dynamic balance shaft keyway and camshaft keyway will be at 12 o'clock and 6 o'clock positions. The correct installation requires reattaching the radiator fan and shroud assembly before connecting the connector and installing the pin-type retainer and timing chain.

The engine cooling fan motor and shroud need to be deleted as the first step before servicing or repairing the harmonic balancer and crankshaft pulley. Follow these steps to remove the accessory drive belt from the tensioner as you rotate its mechanism clockwise. Then uninstall the crankshaft pulley bolt. The Crankshaft Vibration Damper Remover should be used to disconnect the crankshaft pulley. Use silicone sealant on the Woodruff key slot of the crankshaft pulley before installation and complete the procedure within 4 minutes of applying the silicone. The installation of the crankshaft pulley requires a Crankshaft Vibration Damper Installer which should be used along with a Strap Wrench for holding the pulley in position. The bolt installation process starts with tightening it to 120 Nm (89 lb-ft) and follows with a full turn relaxation then continuing to 50 Nm (37 lb-ft) until achieving an additional 90 degrees of torque.

Use a new crankshaft pulley bolt and washer, hold the pulley with a Strap Wrench, and tighten the bolt in four stages: first to 120 Nm (89 lb-ft), then loosen one full turn, next to 50 Nm (37 lb-ft), and finally tighten an additional 90 degrees.
