How to replace or install a Harmonic Balancer in a 2.5L four-cylinder engine on Jeep Wrangler?

Disconnect the cable from the negative terminal of the battery. Remove the drivebelts, tagging each belt as it's removed to simplify reinstallation. If the vehicle has a fan shroud, unscrew the mounting bolts and position the shroud out of the way. Raise the vehicle and support it securely on jackstands. For vehicles with a manual transmission, apply the parking brake and put the transmission in gear to prevent the crankshaft from turning, then remove the crankshaft pulley bolts. For those with an automatic transmission, it may be necessary to remove the starter motor and immobilize the starter ring gear with a large screwdriver while an assistant loosens the pulley bolts. On vehicles with serpentine belts, the pulley and harmonic balancer are combined as one piece, so there are no pulley bolts to remove. To loosen the harmonic balancer retaining bolt, install a bolt in one of the pulley bolt holes, attach a breaker bar, extension, and socket to the harmonic balancer retaining bolt, and immobilize the crankshaft by wedging a large screwdriver between the bolt and the socket before removing the retaining bolt. Remove the harmonic balancer, using a puller if necessary. Apply a thin layer of multi-purpose grease to the seal contact surface of the harmonic balancer. Slide the harmonic balancer onto the crankshaft, ensuring the slot in the hub is aligned with the Woodruff key in the end of the crankshaft. Once aligned, tap the balancer onto the crankshaft with a soft-face hammer, using the retaining bolt to press the balancer into position. Tighten the harmonic balancer-to-crankshaft bolt to the specified torque. Install the crankshaft pulley if equipped on the hub and tighten the bolts to the specified torque, using Locktite on the bolt threads. Finally, install the drivebelts and replace the fan shroud if equipped.

How to remove the Crankshaft Seal and Harmonic Balancer on the 5.7L, 6.1L V8, and 6.4L V8 Hemi engine in Jeep Grand Cherokee?

Taking off the cable, remove it from the negative terminal of the battery. Take off the engine drivebelt and let out the coolant, take off the upper radiator hose and the engine cooling fan. Get out the huge bolt joining the large harmonic balancer to the crankshaft while using a chain wrench round the pulley so that the crankshaft will not turn, and ensure that there is a piece of rubber in between the wrench and the harmonic balancer. With a proper puller remove the harmonic balancer, ensure that outer edge of the puller does not stick on the pulley and the screw of the puller does not touch the threads on the crankshaft nose. If the seal is to be removed and the cover is still fixed on the engine block, this is removed using a seal removal tool or a large screw driver being keen not to harm the area where the seal fits. To install the seal, the bore must be cleaned since it can have old seal material and corrosion, then fit the new seal such that the lip is inside and applying a little oil to the outside of the seal can help in the fitting process. Tighten the seal into the bore with a seal driver or a large socket and hammer until the seal is in a perfect position on the cover flange. Those that have appearances such as grooves on its surface, need the harmonic balancer replacing. Coat the seal lips with engine oil and replace the harmonic balancer keying the Woodruff into the hub and installing the special tool to press it onto splined crank. Put on the harmonic balancer bolt and torque it to the recommended figure. The rest of the installation process is as the removal process in a reverse order until you refill the cooling system.

Jeep Harmonic Balancer eliminates crankshaft vibration and protects engines to ensure that every trail run is a smooth one. In 1945, Jeep began civilian life with a go-anywhere reputation that many family SUVs do not have. Contemporary Jeep interiors combine hose-out wash-and-wear interiors with touch screens, voice recognition and over-the-air updates, allowing a Jeep owner to switch between mud, snow and sand without halting, ending traction drama. Parking lot wave rituals, community trail rides and unlimited swaps provide every Jeep owner with an immediate club. Open roofs and removable doors make the day-to-day commute an invitation to wind-whipped holidays when pavement can end at no point, and even the square posture seems as though it might be time to cross the river. The Harmonic Balancer is mounted to the crankshaft snout using a steel hub, inertia ring and a rubber damper, which absorbs torsional spikes at different points throughout the rev range to ensure bearings live when cylinders are not firing in sequence. Since the Harmonic Balancer holds 360-degree timing indications, tuners use a single quick strobe flash to set ignition. A Harmonic Balancer that is performance rated quashes high-RPM punishment, and thus there is no snaky crank damage on supercharged or towed engines. Install a new Harmonic Balancer prior to extended journeys and the powertrain will run at a lower temperature, produce less noise and be prepared to handle sand or snow.
