There is one bolt in center of pulley/harmonic balancer. Sounds like the harmonic balancer has started going bad..if bolt in center of pulley is loose...which is fairly uncommon tighten which you just tighten Iike any other bolt. If it is tight then you will need the replacement. Replacement is a good bit more involved. Radiator has to be removed, special tool, harmonic balancer pulley remover is required..it will remove pulley. Then you line up pulley with keyway..tap on with rubber hammer until pulley is on far enough for bolt to be started..tighten the bolt and it pulls the pulley all the way into place.
Look at the pulleys with the belt off. Are they aligned? If so then one of the pulleys is bad. This would cause a belt to come off tract. If the balancer is out, check the bolt, tighten it back to where the balancer is back in line with the rest.
"The crankshaft timing pointer must be perfectly aligned with the white mark on the flywheel or flex-plate; the camshaft pulley must be aligned so that the word UP is at the top of the pulley and the marks on the edge of the pulley are aligned with the surfaces of the head. Install the timing belt over the pulleys and tensioners. Loosen the bolt used to lock the timing belt tensioner. Loosen, then tighten the timing belt adjusting nut. Turn the crankshaft counterclockwise until the cam pulley has moved 3 teeth; this creates tension on the timing belt. Loosen, then tighten the adjusting nut and tighten it to 33 ft. lbs. (45 Nm). Tighten the bolt used to lock the timing belt tensioner. Realign the timing belt marks, then install the balancer belt drive sprocket on the crankshaft. Align the front balancer pulley; the face of the front timing balancer pulley has a mark, which must be aligned with the notch on the oil pump body. This pulley is the one at 10 o'clock to the crank pulley when viewed from the pulley end. Align the rear timing balancer pulley (2 o'clock from the crank pulley) using a 6 x 100mm bolt or rod. Mark the bolt or rod at a point 2.9 in. (74mm) from the end. Remove the bolt from the maintenance hole on the side of the block; insert the bolt or rod into the hole. Align the 2.9 in. (74mm) mark with the face of the hole. This pin will hold the shaft in place during installation. Install the balancer belt. Once the belts are in place, be sure that all the engine alignment marks are still correct. If not, remove the belts, realign the engine and reinstall the belts. Once the belts are properly installed, slowly loosen the adjusting nut, allowing the tensioner to move against the belt. Remove the pin from the maintenance hole and reinstall the bolt and washer. Turn the crankshaft 1 full turn, then tighten the adjuster nut to 33 ft. lbs. (45 Nm). Remove the bolt used to lock the timing belt tensioner."
the harmonic balancer is slightly pressed onto the crank shaft. It does require the bolt to hold it into its correct position. If you drive it with the bolt broken the pulley will eventually work its way loose from the crank shaft. This will cause damage to the crankshaft and will cause the accessory belts to come off as well.
Before you change anything,,check and see if everything is in line..Also feel all the pulleys and make sure everything turns ok...If the powersteering pump has been replaced,,sometimes the pulley was not pressed on far enough..If it seem to be the harmonic balancer make sure its not damage and the bolt in the middle is tight...If you remove it..You remove middle bolt,,then you have to use a puller to remove the harmonic balancer itself..unusuall for the harmonic balancer to be bad unless it was hit by something
Hi, it sounds like your harmonic balancer has separated from the crankshaft pulley. There is a rubber cylinder between the pulley and core that bolts to the crankshaft. If you can see the crankshaft turning inside the pulley, replace the balancer. If the crankshaft bolt is turning, your key may have sheared off--that would be very unusual. In either case, you will have to remove the balancer. You will likely need a balancer puller to get it off. Remove the belts and find a way to lock the crankshaft in order to loosen the bolt. If you have a manual transmission, put it in the high gear and set the brake to lock the engine. If you have an automatic, you have have to pull the starter and jam a screwdriver in the flexplate teeth. Once you have the bolt loose, use a puller to remove the balancer. At this point, it may come apart, depending on the type of puller you use. Please let me know if you have questions, and thanks for using FixYa.
no. there should not be any wobble to your harmonic balancer pulley! any wobble to the bottom pulley,means it's out of balance. either a belts too tight,or a harmonic balancer bolts loose. the other belts contribute to the wobble once it begins. check the tourque on the harmonic balancer bolt. it should be about 180 footlbs thank you for choosing fixya.com.
by biggest wheel under the belt are you talking about the lowest wheel on the motor at the bottom of the motor then it is the harmonic balancer the rubber dampener material between the outer and inner metal balancer is coming apart.you should get this replaced as soon as possible.if it separates completely it can cause alot of damage to other components and cost more money to repair the damage
