How to service and repair the harmonic balancer and crankshaft pulley on Ford Escape?

The first step for servicing and repairing the harmonic balancer and crankshaft pulley requires vehicle elevation followed by suspension. Unfasten the bolts which keep the right-hand portion of the lower splash shield in place. First untighten the bolt which retains the crankshaft pulley before removing the accessory drive belt. The crankshaft pulley combined with its retaining bolt must be removed next. The service and repair procedure concludes by following all steps which were performed during removal.

How to service and repair the harmonic balancer and crankshaft pulley on Ford Mustang?

The vehicle must be raised onto a hoist placed in NEUTRAL position for servicing or repairing harmonic balancer and crankshaft pulley. It is necessary to remove the Air Cleaner (ACL) outlet pipe followed by the accessory drive belt. Because the crankshaft pulley bolt operates at torque-to-yield strength do not reuse it. Utilize a Strap Wrench to keep the crankshaft pulley steady when removing the bolt along with its washer. The Crankshaft Vibration Damper Remover will fail to remove the pulley if it starts from an uninitialized pulley bolt position. Thus the bolt should be installed 2 to 3 turns at the start. The Crankshaft Vibration Damper Removers with two 8-mm bolts serve to detach the crankshaft pulley before discarding the crankshaft pulley bolt. The Crankshaft Vibration Damper Installer tool should be used for fitting the new crankshaft pulley. Apply the Strap Wrench to hold the crankshaft pulley during new crankshaft pulley bolt placement before tightening until it reaches 55 Nm (41 lb-ft) torque followed by an 85-degree addition. Reinstall both the accessory drive belt along with the ACL outlet pipe after completion.

How to service the Harmonic Balancer on Ford Ranger?

The service of crankshaft pulley starts with fan shroud removal followed by drive belt bolt loosening. The drive belt must be loosened from its position then removed from the bolt. A three-bolt puller represents the appropriate tool for assembling and disassembling the crankshaft pulley because prying with other objects can cause damage to the assembly. First remove the crankshaft pulley before you can remove its bolt along with the washer afterward to complete the pulley removal process. Put the washer onto the bolt before installation since it will help secure the crankshaft pulley assembly according to its specifications. Fitting the crankshaft pulley assembly with its bolt and washer enables drive belt reinstallation. The final step involves tightening the bolt while reinstalling the fan as well as the shroud.
